Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (Eastern Serbia). Both the morphological and metric characteristics of the teeth are consistent with the attribution to S. hundsheimensis. Unfortunately, the rhinoceros material originated from an uncertain geological context, so there is no firm basis for dating. However, a potential association with a caballoid horse tooth could hint at an age of 600 ka or less for the assemblage, which would indicate a relatively late date for the Hundsheim rhinoceros from Bogovina Cave.

s figure1The rhinocerotid fossil record of Serbia is generally poor and low in taxonomic diversity. A small number of specimens are known from the Miocene of Serbia, including Dicerorhinus aff. sansaniensis Lartet, 1851 (recte Lartetotherium aff. sansaniensis) (Pavlović, 1963), and an unidentified rhinoceros from the Middle Miocene (Mammal Neogene (MN) zone 6) of Prebreza (Toplica, Southern Serbia; Ćirić, 1960; Stefanović, 2002-03; Stefanović and Mijović, 2004). Only one species, the woolly rhinoceros (Coelodonta antiquitatis Blumenbach, 1799), has been documented in the Pleistocene of Serbia so far (Marković, 1998; Nedeljković, 2006). This paper reports on rhinoceros dental remains originating from Bogovina Cave [Bogovinska pećina], situated at the south-eastern foothills of Kučaj Mt. near the town of Boljevac in Eastern Serbia (43°53'49" N, 21°55'31" E; Figure 1). The cave is set in Upper Jurassic to Lower Cretaceous limestones of the Kučај zone (Dimitrijević, 1997) in the central part of the Carpatho-Balkanides. This approximately 1,200 m thick succession of predominantly shallow-water limestones dips steeply (~45°) towards the east (Veselinović et al., 1964). The older Paleozoic clastics, which underlie these karstified limestones, act as hydrogeological barriers, which played a significant role in the formation of Bogovina Cave. Upper Cretaceous to Paleogene siliciclastic, carbonate, and volcaniclastic formations of the so-called Timok Magmatic Complex (Banješević, 2010) cover the western foothills of Kučaj Mt. in the vicinity of the cave. The youngest sedimentary formations are found on the western rim of the Bogovina Basin, a tectonic depression filled with up to 380 m thick Upper Oligocene to Upper Miocene sediments with coal deposits (Cvetičanin and Novković, 1975; Petrović, 1977). With 6 km of explored channels, Bogovina Cave is one of the largest in Serbia (Milanović, 2015), and it is categorized as a spelaeological Natural Monument (Maran, 2010). The fossil material presented in this paper was collected in 1998 at the entrance to the cave where it was probably transported by a temporary cave stream, which is known to be active during high water periods (Pušić and Stevanović, 1994; Dokmanovic et al., 2003; Milanović, 2015). Although the primary geological context of the fossils could not be determined, the fossil material from Bogovina Cave is nevertheless important due to the scarcity of rhinoceros fossils from Serbia.


The fossil material from the locality of Bogovina Cave (Serbia) is stored in the collections of the National Museum Kraljevo (abbreviated NMKVRS) and the Homeland Museum Paraćin (HMP). Rhinoceros remains studied in this paper include: NMKVRS.P13, left P3 or P4; HMP-139b, right P3 or P4; HMP-139a, right p2; HMP-407, right p3; HMP-130, right deciduous tooth (DP4); HMP-131, right M1 or M2; HMP-X, right M1 or M2; HMP-135, left M1 or M2; HMP-136, right M1 or M2; HMP-132 and HMP-134, right upper molar fragments; HMP-129, right m1 or m2. This paper also reports fragments belonging to other mammalian taxa, including: NMKVRS.P11, equid left lower molar (probably m2); NMKVRS.P14 and NMKVRS.P15, bovid right p4 and left M1/M2, respectively.

s figure2The present paper considers morphological characteristics reported by several authors, including Guérin (1980), Fortelius et al. (1993), Lacombat (2006a, 2007), Ballatore and Breda (2013), Pandolfi and Marra (2015), Handa and Pandolfi (2016), and Pandolfi and Erten (2017); the dental terminology is presented in Figure 2. Measurements (in mm) were taken with a digital caliper to 0.01 mm and rounded to the nearest 0.1 mm. The reported measurements for rhinoceros teeth follow Fortelius et al. (1993): length - L (i.e., vestibular length) and width - W (i.e., mesial width for upper teeth, and distal width for lower teeth). The dimensions of Bogovina rhinoceros teeth were compared to the size ranges for S. etruscus, S. hundsheimensis, S. hemitoechus, and S. kirchbergensis, which were obtained based on the data reported by Fortelius et al. (1993), Guérin (1980), Handa and Pandolfi (2016), Pandolfi and Erten (2017), and Pandolfi and Marra (2015). The methodologies concerning bovid and equid teeth follow Gentry (1999) and Eisenmann et al. (1988), respectively. The dental anatomical notation follows the system proposed by Smith and Dodson (2003) for mammalian dentition, where premolars and molars in upper jaws are abbreviated as Pn and Mn (n = tooth number) and as pn, and mn in lower jaws, while deciduous teeth are indicated by D (e.g., DP4 for deciduous upper fourth premolar).

s figure3Upper dentition: The specimen NMKVRS.P13 (Figure 3A-E) is a left P3 or P4. Despite pronounced wear, this middle-large sized tooth is rather well-preserved, consisting of a complete crown (showing grey enamel and dark brown dentine) and partially preserved roots. The enamel surface is characterised by the presence of several dark vertical and subvertical lines (these lines may frequently be present but are not ubiquitous among Pleistocene rhinoceroses). The crown displays some rounding and polishing, indicating water transport as a taphonomic agent. The surface bears patches of black manganese coating and yellowish iron-oxide staining. In occlusal view, the crown is vestibulo-lingually wide and mesio-distally short, showing a rectangular outline. The occlusal surface is semi-smooth and polished showing the interior valley, the medifossetta, as well as the postfossetta. Mesially, the ectoloph curves quite drastically towards the interior of the tooth. No constriction of the protocone can be observed. An oblique lingual cingulum is present.

The fossil designated HMP-139b (Figure 3F-H) is a right P3 or P4, consisting of a damaged dark brown crown with very pronounced rounding and polishing presumably by water transport. Large parts of the mesial, distal, and vestibular enamel are missing. The preserved occlusal surface shows marked wear, the presence of an interior valley, a single crochet, and the postfossetta. A partially preserved cingulum is present on the lingual and distal sides. The protocone seems to display a very slight constriction, although the pronounced wear makes this difficult to assess.

s figure4HMP-131 (Figure 4A-E) is a rather well-preserved and complete crown of a large right molar (M1 or M2), with little wear, showing grey-yellow enamel, with extensive black manganese coating. The crown does not display much taphonomically-induced rounding or polishing. In occlusal view, the tooth is trapezoidal showing a well-marked ectoloph profile with a strong paracone fold, an open medisinus, a single crochet, and the postfossetta. Very shallow expressions of the antecrochet and crista can be observed; if the specimen showed more advanced wear, these features would have not been observed. The base of the protoloph appears rather bulbous (especially in lingual view); the protocone shows only a very slight constriction. In both the mesial and distal views the molar appears remarkably brachydont. The outlet of the interior valley displays a classic V-shape in lingual view. In vestibular view, the crown is slightly rough and shows some vertical and subvertical greyish lines. These lines may also be present in other portions of the crown, but they are not visible due to the manganese coating. Cingula are present on the bases of both the protocone and the hypocone, mesial and distal sides; the horizontal lingual cingulum continues as a prominent oblique mesial cingulum.

A right M1 or M2, specimen HMP-X (Figure 4F-J) presents a rather complete but worn crown, with very little preserved of the roots; grey enamel is heavily yellow-stained (iron oxides), showing regions with manganese coating. The specimen displays only minimal taphonomic smoothing, confined mostly to the damaged roots. The occlusal view shows a trapezoidal-shaped crown typical for upper molars. Despite being obscured by the localised enamel damage, the presence of a paracone fold on the ectoloph profile is evident. A single crochet is present, and there is an open medisinus and a distinct postfossetta. The occlusal morphology does not include the presence of an antecrochet or crista. The protocone is markedly constricted. The cingulum can be observed on lingual, mesial, and distal (around the base of the metastyle) sides.

The specimen HMP-135 (Figure 4K-O) is a left M1 or M2 consisting of a well-preserved and complete crown without roots, showing pronounced wear and grey-coloured, iron-oxide stained enamel. The crown shows rounded and polished surfaces (indicating water transport). A trapezoidal shape can be observed in occlusal view. The ectoloph profile displays a distinct, strong paracone fold. There is a relatively large single crochet, an open medisinus and the postfossetta. There is no antecrochet or crista. The base of the protoloph is rather bulbous, which is more evident in the lingual view; there is a strong constriction of the protocone. The outlet of the lingual valley shows an enlarged V-shape in lingual view. The enamel surface shows the presence of a large number of vertical and subvertical greyish-brown-yellow lines. A small portion of a mesial cingulum can be seen under the protocone constriction, and also on the distal side (smoothed via taphonomic processes). The tooth appears rather brachydont.

s figure5The specimen HMP-136 (Figure 5A-B) is a right M1 or M2, and it consists of a damaged crown, with vestibular part (ectoloph) and roots missing; the tooth has light brown colouration, different from other specimens reported in this paper. However, like some other specimens (HMP-131 and X), the mesial parts of the crown under the cingulum display black manganese staining. Despite damage, the trapezoidal crown outline is obvious. The wear is not pronounced, so many details of the occlusal morphology can be assessed. There is a rather strong crista and a large crochet; there is also a small second crista located between the crochet and the crista. The medisinus is open. Only a hint of an antecrochet can be observed. The postfossetta is marked. The protocone is only very lightly constricted and bulbously inflated. A horizontal cingulum is present on the lingual, distal, and mesial sides; the mesial cingulum presents a very prominent and sharp, continuous and oblique protuberance.

The fossil designated HMP-132 (Figure 5C-D) represents only a vestibular right upper molar crown fragment with grey-coloured, smooth and polished enamel, showing several vertical and subvertical brown to yellow lines. The ectoloph profile bears a strong paracone fold. A part of the distal cingulum is preserved at the base of the metastyle.

The specimen HMP-134 (Figure 5E-F) is a mesial half of the vestibular crown fragment of a larger right upper molar. The smooth and polished grey-coloured enamel displays many vertical and subvertical brown to yellow lines. A marked paracone fold is present.

The specimen HMP-130 (Figure 5G-H) is a right upper deciduous tooth, probably a DP4. It consists of a very worn and damaged crown, with grey-bluish enamel with iron-oxide stains. The most damaged regions of the crown are the metacone and the hypocone; the roots are mostly missing, and only the lingual ones are preserved to some length. The crown shows a trapezoidal shape in occlusal view, with the distal side shorter than the medial one; the ectoloph profile is rather well marked (despite the damage to its mesial and distal portions), showing a strong paracone fold. The occlusal surface is smooth and polished (shiny), showing the lingual valley and the postfossetta, an open medisinus, and a single, quite massive crochet. The protocone, characterised by a pronounced constriction, appears remarkably bulbous. Unfortunately, the hypocone has been broken off. The enamel surface presents several vertical and subvertical brown lines. The cingulum can be seen on the preserved mesial side.

s figure6Lower dentition: The fossil designated HMP-129 (Figure 6A-E) is a right m1 or m2, and it represents a perfectly preserved yellow-grey-coloured crown with mild wear, without roots. In occlusal view the crown shows a distinct paralophid and a well-defined mesial valley (i.e., trigonid basin); the mesial valley is narrower than the distal one, and both of them show a V-shape outline in lingual view. The opening of the vestibular syncline is right-angled. Oblique and continuous mesial and distal cingula are present (with interproximal wear), and they continue partially on the vestibular side.

A right p3 or p4 designated HMP-407 (Figure 6F-J) preserves a complete worn crown and partial roots. The enamel is mostly yellow to brown, due to iron-oxide staining. This specimen does not show taphonomically induced rounding or polishing. It displays a relatively small mesial valley and a larger distal one, both with V-shaped outlines in the lingual view, and a right-angled vestibular syncline. Mesial and distal cingula (oblique and continuous) are evidently present, though obscured by interproximal wear; a faint, horizontal and discontinuous cingulum is present on the vestibular side of the crown as well.

A right p2 known as HMP-139a (Figure 6K-O) represents a small-sized, yellow-grey crown in an excellent state of preservation, with only a mild degree of occlusal wear in its mesial portion; roots are missing. The crown displays a much reduced paralophid and metalophid, a well-developed hypolophid, a well-defined, lingually V-shaped, distal valley (i.e., talonid basin), a wide and right-angled opening of the vestibular syncline, and gracile mesial and distal cingula (the latter is reduced due to interproximal wear).

Metric Data

Dimensions for the well-preserved specimens are provided in Table 1. The comparative data (length and width ranges) are provided in Table 2. When regarded as P3, the specimen NMKVRS.P13 is within the reported ranges for Stephanorhinus etruscus, S. hundsheimensis, S. hemitoechus, and narrower and (only marginally) shorter than S. kirchbergensis P3. When regarded as P3, however, NMKVRS.P13 is smaller (shorter and narrower) than S. kirchbergensis P4, marginally shorter than S. hemitoechus P4 and marginally narrower than S. hundsheimensis P4. The upper molar HMP-X is shorter than S. kirchbergensis M1, while within the ranges for M1s of other taxa; HMP-X is within the ranges for most of the M2 comparative taxa, albeit smaller than S. kirchbergensis M2 and below the width range reported for S. hemitoechus M2. The HMP-131 molar falls within the ranges for all the comparative taxa, both when viewed as M1 and M2, with a notable exception of being somewhat longer than S. etruscus M1. The HMP-135 upper molar fits the M1 and M2 data for three species (S. etruscus, S. hundsheimensis, S. hemitoechus), while being narrower than S. kirchbergensis M1, and smaller (in both dimensions) from S. kirchbergensis M2. The HMP-130 deciduous upper tooth is narrow relative to the (permanent) molars of all the comparative groups.

The HMP-139a lower second premolar is within the ranges of all taxa, except being marginally longer than Stephanorhinus hemitoechus p2. The specimen HMP-407 is within the ranges for most taxa both when viewed as p3 and p4; it only differs from S. kirchbergensis by being marginally narrower when viewed as M1, and by being narrower and marginally shorter when viewed as M2. Finally, the lower first or second molar HMP-129 is within the reported ranges for most groups, both when viewed as m1 and m2; however, this molar is narrower than S. kirchbergensis m1, and smaller (shorter and narrower) than S. kirchbergensis m2.

The Accompanying Mammalian Fauna

s figure7In addition to the rhinoceros material, dental remains of other Pleistocene large mammals were also collected from the site, including horse (Equus sp.) and an indeterminate bovid. These additional specimens display shiny, brown and black surfaces, which could indicate that the fossils originated from the same stratigraphic context as many of the rhinoceros teeth (e.g., HMP-130, 139b). However, different stratigraphic provenance cannot be excluded.

The equid (Equidae) material consists of an isolated left lower molar (m1 or m2) NMKVRS.P12 (Figure 7A). The genus Equus may be separated into two different lineages: the stenonid (zebroid) and the caballoid (true) horses. The most obvious dental differences between the two groups can be seen in the lower cheek teeth, namely, in the morphology of the metaconid-metastylid loops (the double knot) and in the shape of the entoflexids (i.e., linguaflexid sensu Skinner et al., 1972) (Forstén, 1992). Stenonid lower premolars and molars are characterised by the V-shaped entoflexid, and concave protoconids and hypoconids; conversely, caballoids show U-shaped entoflexid with straight protoconids and hypoconids, and a rounded metaconid (Arceredillo, 2008). As seen in Figure 7A, the specimen from Bogovina Cave clearly shows U-shaped entoflexid, thus indicating a caballoid horse. Furthermore, the size of molar (L = 33.8 mm, W = 14.7 mm; measured at the occlusal surface, excluding cement) is comparable to the large-sized group of caballoid horses of Forstén and Dimitrijević (2004), well-known from the caves and rock shelters of the Central Balkans. Indeterminate bovid (Bovidae) dental specimens were also discovered: a right permanent lower fourth premolar (p4) NMKVRS.P14 (Figure 7B; L = 25.3 mm, W = 16.8 mm) and a left upper molar (M1 or M2) NMKVRS.P15 (Figure 7C; L = 31.5 mm, W = 20.5 mm). We did not attempt to classify these two isolated specimens at genus and species levels, due to the well-known fact that large bovine teeth show great variability of proportions and structures (Sher, 1997).


s figure8The genus Stephanorhinus Kretzoï, 1942, comprises several extinct rhinoceros species that lived in the Palaearctic region during the Neogene to Quaternary. All members of the genus were dolichocephalic, two-horned rhinoceroses, with pronounced molarization of premolars and with no functional incisors (Fortelius et al., 1993). The Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902, represents one of the four species of the genus Stephanorhinus that existed in the European Pleistocene (see Figure 8), along with the Etruscan rhinoceros, S. etruscus Falconer, 1868 from the Early Villafranchian to Early Galerian (i.e., latest Pliocene to Early-Middle Pleistocene transition; Pandolfi et al., 2017a), the narrow-nosed rhinoceros, S. hemitoechus Falconer, 1859 from the Middle Galerian and Aurelian (i.e., Middle to Late Pleistocene; Guérin, 1980; Stuart and Lister, 2007, 2012; Pandolfi et al., 2013; Pandolfi et al., 2017b), and the Merck’s rhinoceros, S. kirchbergensis Jäger, 1839 from the Middle Galerian and Aurelian (i.e., Middle to Late Pleistocene; Pandolfi and Marra, 2015). According to Guérin (1980), S. hundsheimensis (syn. Dicerorhinus etruscus brachycephalus) and S. hemitoechus both evolved from the species S. etruscus, but others (Fortelius et al., 1993; Lacombat, 2007) link S. hundsheimensis with the species S. jeanvireti from the European Late Ruscinian-Early Villafranchian (i.e., Late Pliocene; Lacombat, 2007; Ros-Montoya et al., 2017). Another hypothesis (Mazza, 1988; Van der Made, 2000) sees S. hundsheimensis as an Asian migrant. The evolutionary origin of the Hundsheim rhinoceros remains unresolved, as does the more general issue of the phylogenetic relationships within the genus Stephanorhinus. Moreover, the genus Stephanorhinus is probably paraphyletic as currently defined, which is indicated both by the morphological (Pandolfi et al., 2015, 2016) and molecular (Cappellini et al., 2019) data. The analysis of dental enamel proteome of an isolated lower molar classified as Stephanorhinus ex gr. etruscus-hundsheimensis from the 1.77 Myr old site of Dmanisi (South Caucasus, Georgia) conducted by Cappellini et al. (2019) demonstrated that this individual represents a sister group to the clade formed by Coelodonta antiquitatis and S. kirchbergensis, implying that the genus Stephanorhinus includes at least two distinct evolutionary lines - thus urging for a systematic revision of the genus.

s figure9According to Kahlke and Kaiser (2011), Stephanorhinus hundsheimensis was a long-legged rhino with cursorial limb proportions and a head posture which allowed it to feed both as a grazer and browser on the vegetation of intermediate height. A reconstruction of S. hundsheimensis with its calf in its hypothetical palaeoenvironment (after Gianfranco Mensi, 2015) is proposed here in Figure 9. Based on the pollen content of sediment adhering to skeletal elements of large fauna from the approximately 1.8 to 1.1 Ma old lacustrine basin succession of Leffe (Italian Alps), S. etruscus-hundsheimensis was associated with different palaeoenvironmental conditions, ranging from a warm-temperate climate with dense mixed forest to conifer forest to cold-temperate climate with open xerophytic communities and steppe with birch trees (Betula sp.) and sparse woodland patches (Ravazzi et al., 2009). Recently, Szabó et al. (2017) had evaluated the Leffe palaeoenvironment using stable carbon and oxygen isotope compositions of rhinoceros tooth enamel, and their results indicated an open woodland-xeric grassland environment. This is in accordance with the mesowear study by Kahlke and Kaiser (2011), which revealed S. hundsheimensis as the most ecologically tolerant rhinoceros of the Palaearctic Plio-Pleistocene, with an extreme dietary variability (ranging from a grazing regime to one of predominantly browsing). Though successful over a long period time in the western Palaearctic, S. hundsheimensis finally became extinct around 0.6-0.5 Ma (but see Guérin et al., 1992), possibly due to the bilateral competition with the strict browser S. kirchbergensis and the specialised grazer S. hemitoechus (Kahlke and Kaiser, 2011). However, it must be noted that there is no direct evidence for coevality of S. hemitoechus and S. hundsheimensis (see Pandolfi et al., 2013), so the presumed competition between the two species likely did not contribute to the demise of S. hundsheimensis. Often misidentified with other Pleistocene rhinoceros taxa (e.g., S. etruscus, S. kirchbergensis), S. hundsheimensis is also known under several other synonyms: Rhinoceros hundsheimensis Toula, 1902; Rhinoceros etruscus var. heidelbergensis Freudenberg, 1914; Dicerorhinus hundsheimensis Toula, 1902; Dicerorhinus handzellensis Wang, 1928; Dicerorhinus hemitoechus intermedius Cigala-Fulgosi, 1976; Dicerorhinus etruscus brachycephalus Guérin, 1980. Having widely been discussed by several authors (e.g., Guérin, 1980; Fortelius et al., 1993; Lacombat, 2006a, 2006b, 2007; Pandolfi and Erten, 2017), the geographical origin, history, general characters, and distinguishing anatomical and odontological features of S. hundsheimensis are not treated in the present paper.

Due to the substantial intraspecific differences and, conversely, interspecific likenesses, it is sometimes difficult to discriminate between different species of the Stephanorhinus genus. However, dental material is sometimes particularly useful in this regard, showing diagnostic traits for different species (e.g., Guérin, 1980; Fortelius et al., 1993; Lacombat, 2005, 2006a; Billia, 2007, 2008, 2011; Van der Made, 2010; Pandolfi and Marra, 2015; Pandolfi and Erten, 2017; Pandolfi et al., 2017b). Moreover, teeth (as enamel-coated structures) have high preservation potential, making them more frequent and better preserved relative to the other skeletal elements.

The teeth from Bogovina Cave are clearly brachydont, as expected for Stephanorhinus hundsheimensis (Guérin, 1980; Fortelius et al., 1993; Lacombat, 2007). In terms of size, most of the specimens fit the metric data reported for S. hundsheimensis. As expected for a deciduous specimen, HMP-130 is small (narrow) relative to Stephanorhinus permanent upper molars. The crochet in S. hundsheimensis upper premolars is variable (absent, single, double, triple, or more), but it is always present (single, rarely double) in upper molars (Lacombat, 2006a; Ballatore and Breda, 2013). Single crochet can be observed in HMP-136b, while NMKVRS.P13 lacks the trait; as far as the molars are concerned, a distinct single crochet is present in the upper permanent molars from Bogovina Cave (HMP-X, 135, 136), as well as in the deciduous tooth HMP-130. Though generally frequent in the upper teeth of the Hundsheim rhinoceros (Lacombat, 2007), the crista is variable in P3, P4, M1, M2, and M3 (single, double, multiple, or absent), being consistently present only in P2 (Ballatore and Breda, 2013). The crista is completely absent in both upper premolars and two upper molars (HMP-X and HMP-135) from Bogovina Cave; however, other molars show either a very shallow (HMP-131) or a strong (HMP-136) single crista. As in other Stephanorhinus species, the antechrochet is usually absent in the upper molars of S. hundsheimensis (with the exception of M3), but a single antecrochet can also be present (Lacombat, 2006a). The majority of upper molar specimens from Bogovina Cave show no development of antecrochet whatsoever, with the exceptions of HMP-131 and HMP-136, which show only shallow expressions of the trait. In the upper premolars of S. hundsheimensis the antecrochet is mainly absent (Lacombat, 2006a), as is in both upper premolars from Bogovina Cave. According to Ballatore and Breda (2013) the paracone fold is generally strong in upper molars and weak (but present) in upper premolars of S. hundsheimensis. Moreover, the paracone fold is more developed in S. hundsheimensis than in S. etruscus (Lacombat, 2007). Invariably, a marked paracone fold can be observed in all upper molars from Bogovina Cave, which preserve the vestibular portion of the crown. Although hard to assess in the premolars, due to the wear (NMKVRS.P13) or damage (HMP-139b), a weak expression of the trait seems to be present in both cases. Highly variable (and thus non-diagnostic) for the Stephanorhinus upper molars, protocone constriction is absent (or rarely present, but very weak) in the upper premolars of S. hundsheimensis (Lacombat, 2006a; Ballatore and Breda, 2013). As expected, the molars from Bogovina Cave display variable expressions of protocone constriction (weak in HMP-136, and strong in HMP-X and HMP-135); the deciduous specimen HMP-130 also shows strong protocone constriction. Similar to S. hundsheimensis premolars, protocone constriction is absent to (possibly) very weak in NMKVRS.P13 and HMP-136b, respectively. The medisinus is always open in the upper dentition from Bogovina Cave, and one premolar (NMKVRS.P13) shows a medifossetta (i.e., feature resulting from the fusion between crochet and crista; Antoine, 2002). The angle between crochet and ectoloph (metacone) could only be assessed in three molars, and it is flat in two (HMP-131, 135) and obtuse in one (HMP-X). Deciduous HMP-130 displays a flat angle between the crochet and the ectoloph. In the M1/2 sample from Isernia La Pineta, this angle can be both flat and obtuse (Ballatore and Breda, 2013). The angle between crochet and metaloph is mostly obtuse in the upper molars (HMP-135, 136, X) and deciduous upper tooth HMP-130, but the angle is right in one molar (HMP-131); the upper premolar HMP-136b also shows an obtuse crochet/metaloph angle. This fits well with the Isernia La Pineta sample, in which the angle between crochet and metaloph in M1/M2 is generally obtuse or sometimes right-angled, in P3 it is generally right-angled, and in P4 it is generally obtuse, though sometimes right-angled (Ballatore and Breda, 2013). Regarding cingula, the upper teeth from Bogovina Cave are in agreement with the distribution reported by Lacombat (2006a) for Stephanorhinus hundsheimensis. As expected (Lacombat, 2006a), no cingula are observed on vestibular sides of the teeth. The lingual cingulum is present in both upper premolars, which is characteristic for S. hundsheimensis according to Lacombat (2006a); it is also present in three molars (HMP-131, X, 136), but absent in two (HMP-135, 130). Furthermore, both the mesial and distal cingula are found in four molars (HMP-131, X, 135, 136); the mesial alone can be seen in the deciduous HMP-130, and the molar fragment HMP-132 shows a part of the distal cingulum.

The morphology of the lower dentition from Bogovina Cave is for the most part in agreement with the characterisation provided by Lacombat (2006a, 2007). According to Lacombat (2007), the mandibular premolars of Stephanorhinus hundsheimensis display V-shaped valleys (although the distal valleys can be broad V-shaped), while mandibular molars display V-shaped to broad V-shaped mesial valleys and broad V-shaped to U-shaped distal valleys. The HMP-407 lower premolar shows a V-shaped mesial and broad V-shaped distal valley (although this trait is hard to assess due to the high degree of wear). The lower second premolar HMP-139a displays a V-shaped distal valley. The HMP-129 m1/m2 shows V-shaped mesial and distal valleys. The openings of vestibular synclines in all three specimens are wide, about right-angled. Continuous mesial and distal cingula are present in HMP-407 and HMP-129, as expected for the p3/p4 and m1/m2 of S. hundsheimensis (Lacombat, 2006a; Ballatore and Breda, 2013). The lower p2 from Bogovina also shows both mesial and distal cingula; although Lacombat (2006a) regarded the mesial cingulum to be absent from the lower p2 in all the Pleistocene species of the genus Stephanorhinus, Ballatore and Breda (2013) found it to be present in the p2 sample of S. hundsheimensis from Isernia La Pineta. Additionally, the lower teeth from Bogovina Cave invariably show the presence of a discontinuous vestibular cingulum, which is again reminiscent of the Isernia La Pineta sample.

Overall, the analysis suggests that the rhinoceros dentition - belonging to two or more distinct individuals - from Bogovina Cave can be ascribed to the species Stephanorhinus hundsheimensis Toula, 1902, and we found no compelling reason to classify any of the specimens differently. Features of the upper premolars (no antecrochet; weak paracone fold; absent or very weak protocone constriction; lingual cingulum present), the upper molars (single crochet; variable crista; marked paracone fold; absent to shallowly expressed antecrochet; mesial and lingulal cingula; no medifossetta; weak to strong protocone constriction), the deciduous premolar (no crista; no antecrochet; no medifossetta; protocone constriction present), and the lower premolars and molars (V-shaped mesial and distal valleys; present mesial and distal cingula) are all in accordance with our taxonomic attribution. Therefore, the material from Bogovina Cave represents, to our knowledge, the first find of the Hundsheim rhinoceros in Serbia, and (together with the woolly rhinoceros) the second Pleistocene rhinoceros species discovered in Serbia. Geographically, the closest record of S. cf. hundsheimensis comes from Layers 5 and 6 of Trlica near Pljevlja in northern Montenegro (Dimitrijević, 1990, 1996; Codrea and Dimitrijević, 1997). Based on the finds of small mammals, Layers 5 and 6 were correlated with the Mimomys savini-pusillus Zone of the Early Pleistocene by Bogićević and Nenadić (2008), while Vislobokova and Agadjanyan (2016) dated these layers to post-Villafranchian times (i.e., the early phase of the Middle Pleistocene, MIS 19). In addition, Vislobokova and Agadjanian (2015) reported a few more isolated rhinoceros teeth from the lower levels (Layers 10 and 11) at Trlica, and identified them as S. etrusctus; according to Pandolfi et al. (2017a), however, these specimens morphologically resemble S. hundsheimensis. Vislobokova and Agadjanyan (2016) correlated Layers 10 and 11 with the second half of the Early Pleistocene (i.e., Late Villafranchian, MNQ 18 zone). The Southeastern European record also includes the fossils from the Galerian site of Subpiatră in Romania (Codrea and Czier, 1991), and from the latest Villafranchian sites of Platanochori-1 and (possibly) Apollonia in Greece (Konidaris et al., 2015). S. hundsheimensis (or S. cf. hundsheimensis) is known from numerous other sites throughout Europe and Western Asia. The species is attested in Britain (an overview is available in Breda et al., 2010) and France (various sites, e.g., Guérin, 1980; Lacombat, 2006a, 2006b, 2007). In Spain, the Hundsheim rhinoceros is reported from the Late Villafranchian sites of Fuente Nueva-3 and Barranco Léon 5 (Lacombat, 2010), Venta Micena (Santafé-Llopis et al., 1987; Madurell-Malapeira et al., 2014), and possibly from El Molinar (Van der Made and Montoya, 2007). According to some authors (Cerdeño, 1993; Van der Made, 2010; Pandolfi et al., 2017a) the specimens from Venta Micena, in fact, represent S. etruscus. The Hundsheim rhinoceros is also present in the Italian fossil record, at Galerian sites such as Isernia-La Pineta (Ballatore and Breda, 2013), Cava Redicicoli (Marra et al., 2014), Tour de Grimaldi (Lacombat and Moullé, 2005), San Colombano al Lambro (Caccia, 1928; Cantaluppi, 1969; Persico et al., 2015), and others. Three exceptionally preserved S. hundsheimensis skulls come from the Castell’Arquato area (Piacenza; Monesi et al., 2016; Bona and Sala, 2016). The earliest possible record comes from the latest Villafranchian of Pietrafitta (Perugia, central Italy), ascribed to Stephanorhinus cf. hundsheimensis by Mazza et al. (1993), based mainly on the postcranial morphology; however, the Pietrafitta rhinoceros was later reassigned to S. etruscus by some other authors (Van der Made, 2010; Pandolfi and Petronio, 2011; Pandolfi et al., 2015; Pandolfi and Erten, 2017; Pandolfi et al., 2017a). In Germany, S. hundsheimensis is recorded at several early Middle Pleistocene sites such as Süssenborn and Voigtstedt (Kahlke, 1965, 1969; Kahlke and Kaiser, 2011), and Mauer and Mosbach 2 (Fortelius et al., 1993; Schreiber, 2005; Koenigswald et al., 2007). The holotype of the species comes from the early Middle Pleistocene site of Hundsheim in Lower Austria (Toula, 1902), while in neighbouring Slovakia, S. cf. hundsheimensis is recorded at the early Middle Pleistocene of Levický Vápnik (Zervanová, 2014). In Turkey, S. hundsheimensis is recorded in the late Early Pleistocene of Denizli Basin in Anatolia (Pandolfi and Erten, 2017). Pavlova (1925) also reported the species from Tiraspol’ (at present the Pridnestrovian Moldavian Republic) as Rhinoceros etruscus var. heidelbergensis Freudenberg, 1914; however, the remains were later reassigned to Dicerorhinus etruscus (Falconer) (= Stephanorhinus etruscus [Falconer]) (Belyaeva and David, 1975). In the South Caucasus region, S. cf. hundsheimensis was reported from the latest Villafranchian site of Kurtan in Armenia (Mkrtchyan et al., 2011), and S. hundsheimensis (=Dicerorhinus etruscus brachycephalus sensu Guérin, 1980) was reported from the Acheulean layers of Kudaro-1 Cave in Georgia (Baryshnikov and Guérin, 1986). The Mousterian site of Erivan I (Armenia) is particularly important because it possibly documents a late (MNQ 26 zone) survival of the species in Caucasus (Baryshnikov et al., 1989; Guérin et al., 1992). However, the material is scarce, consisting of postcranial elements only, so the interesting scenario of the Caucasus acting as refugium cannot be confirmed.

The Hundsheim rhinoceros from Bogovina Cave can only be broadly dated to the late Early and early Middle Pleistocene, based on the known stratigraphic range of the species in Europe. Since the teeth show differences in colour and degrees of smoothing/polishing, they probably originated from different strata and were exposed to differential degrees of water-induced transport. As the geological context is lacking, it is very hard to hypothesise a more precise chronology of the material. Nevertheless, the find of a caballoid horse molar could be taken as potentially indicative in this regard. The earliest caballoid horses in Europe occur in the early Middle Pleistocene (Galerian), as indicated by the 600 ka old mixed stenonid and caballoid equid assemblage from Süssenborn in Germany (Musil, 1969; Forstén, 1986). If rhinoceros dentition from Bogovina Cave (or at least some specimens) originated from the same stratigraphic horizon as the caballoid horse molar, this would suggest an age of 600 ka or less (Middle to Late Galerian). However, according to Forstén and Dimitrijević (2004) most caballoid horse fossils from the Central Balkans probably come from the Late Pleistocene. Despite the fact that caballoid horses can survive in a wide range of habitats, the presence of a caballoid molar at Bogovina Cave may also indicate a humid, closed, and cooler environment (Van Asperen et al., 2012). By contrast, the association of stenoid horses with Stephanorhinus cf. hundsheimensis at Trlica (Codrea and Dimitrijević, 1997) is seen as an indicator of drier, warmer, and more open landscapes (Van Asperen et al., 2012). This apparent palaeoenvironmental variability is in accordance with studies (Ravazzi et al., 2009; Kahlke and Kaiser, 2011), which pointed to the extremely wide ecological domain of the Hundsheim rhinoceros.
