FIGURE 2. Fossil remains of Eomellivora fricki (Pia, 1939) from Wien XII-Altmannsdorf and Gaiselberg. 1-4, Holotype NHMW 2016/0065/0001 from Wien XII-Altmannsdorf,left maxilla fragment, 1, lateral view, 2, occlusal view, 3, rostral view, 4, caudal view; 5-6, right maxilla fragment, 5, lateral view, 6, occlusal view; 7, fragment of the left zygomatic arch; 8, fragment of the left temporo-mandibular joint; 9-10, fragment with the right mastoid process (mp), the ventral part of the nuchal crest (nc), the external auditory meatus (eam), and part of the glenoid cavity (gc), 9, lateral view, 10, dorsal view; 11-14, NHMW 1977/1948/0130 right hemimandible from Gaiselberg. 11, lateral view, 12, medial view, 13, occlusal view, 14, ventral view.

FIGURE 3. Phylogenetic relationship of Eomellivora fricki within Eomellivora, and of some extinct Neogene mustelids and living carnivorans. Canis lupus is the outgroup. Searches were performed by means of the Branch and Bound and a Bootstrap analysis through 1000 replicates. A single tree is obtained (length 172 steps, consistency index (CI)=0.4593, retention index (RI)=0.5811). The numbers below nodes are Bremer indices, and the numbers above nodes are Bootstrap support percentages (only shown ≥ 50). Letters (A-K) indicated selected nodes. The synapomorphies for each node are reported in Table 4.
