An outline of the European Quaternary localities with freshwater gastropods: data on geography and updated stratigraphy

Elisavet Georgopoulou, Thomas A. Neubauer, Andreas Kroh, Mathias Harzhauser, and Oleg Mandic

Plain Language Abstract

Fossil and subfossil freshwater gastropods of the European Quaternary have been studied extensively by numerous authors during the nineteenth and twentieth centuries. Despite the wealth of information, these papers usually focus on regional aspects. Geographic names, however, may have changed due to politics and the stratigraphy is outdated in many cases. Since then, numerous papers improved the taxonomic understanding of certain groups of freshwater gastropods and revised the often confused nomenclatural history. Nevertheless, no efforts were made to collect and summarize the data on a pan-European scale in order to compare them. This study focuses specifically on recording Pleistocene and Holocene localities of Europe and some adjacent Asian countries bearing freshwater gastropods, combined with updated stratigraphic information when available. This resulted in a dataset of 1473 localities, which may serve as a base for future analyses of Eurasian post-Pliocene freshwater systems and their biota.

Resumen en Español

Un resumen de las localidades del Cuaternario europeo con gasterópodos de agua dulce: datos sobre la geografía y la estratigrafía actualizada

Los fósiles y los subfósiles de gasterópodos de agua dulce del Cuaternario europeo han sido ampliamente estudiados por numerosos autores en los siglos XIX y XX. A pesar de la gran cantidad de información acumulada, por lo general estos documentos se centran en los aspectos regionales. Los nombres geográficos, sin embargo, pueden haber cambiado debido a razones políticas y a que la estratigrafía es anticuada en muchos casos. Desde entonces, numerosos trabajos han mejorado la comprensión taxonómica de ciertos grupos de gasterópodos de agua dulce y han revisado la historia nomenclatural que a menudo ha sido confusa. Sin embargo, no se hicieron esfuerzos para recopilar y resumir los datos a escala paneuropea con el fin de compararlos. Este estudio se centra específicamente en el registro de localidades del Pleistoceno y Holoceno de Europa y algunos países asiáticos adyacentes que proporcionan gasterópodos de agua dulce, adjuntando la información estratigráfica actualizada cuando está disponible. Esto dio como resultado un conjunto de datos de 1473 localidades, que puede servir como base para futuros análisis de los sistemas de agua dulce euroasiáticos post-pliocenos y su biota.

Palabras clave: gasterópodos de agua dulce; base de datos; puntos de geo-referencia; Pleistoceno; Holoceno

Résumé en Français

Une brève synthèse des localités à gastropodes d'eau douce du Quaternaire d'Europe : données concernant la géographie et les mises à jour de la stratigraphie

Les gastropodes d'eau douce fossiles et subfossiles du Quaternaire d'Europe ont été étudiés en détail par de nombreux auteurs pendant les XIXème et XXème siècles. Malgré l'abondance d'informations, ces articles se concentrent généralement sur des aspects régionaux. Les noms géographiques peuvent cependant avoir changé pour des raisons géopolitiques et la stratigraphie est obsolète dans de nombreux cas. Depuis lors, de nombreux articles ont amélioré la compréhension de la taxonomie de certains groupes de gastropodes d'eau douce et ont révisé leur histoire nomenclaturale, souvent embrouillée. Néanmoins, aucun effort n'a été fait pour collecter et effectuer la synthèse des données afin de les comparer à l'échelle pan-européenne. La présente étude se concentre précisément sur l'inventaire des localités à gastropodes d'eau douce du Pléistocène et de l'Holocène d'Europe et de certains pays adjacents d'Asie, combiné si possible avec une mise à jour des informations stratigraphiques. Cela a abouti à un jeu de données de 1473 localités, qui peut servir de base pour de futures analyses des systèmes d'eau douce post-pliocènes et de leurs biota.

Elisavet Georgopoulou is a PhD student at the Natural History Museum Vienna, Austria. She holds a master degree in Management of Terrestrial and Marine Resources. Since 2013, she studies the biogeography of Pleistocene to Recent freshwater gastropods of Europe. A main focus is to reveal the underlying mechanisms that shaped the present distribution pattern.

Thomas A. Neubauer is a postdoctoral researcher at the Geological-Paleontological Department of the Natural History Museum Vienna, Austria. His current research focus is the reconstruction of species distribution patterns of freshwater gastropods during the Late Cenozoic, as part of the FreshGEN database project (www.marinespecies.org/freshgen). Above that, his research interests include the taxonomy and nomenclature of Cenozoic freshwater gastropods, as well as morphometric analyses and their applications in evolutionary studies.

Andreas Kroh is a researcher and curator at the Natural History Museum in Vienna, Austria. His main research interests are echinoderms, with focus on the phylogeny, nomenclature and systematics of echinoids. Being a paleontologist with a strong interest in bridging the gap between life and earth sciences, he is actively involved in various efforts to ease access to biodiversity and taxonomic data on echinoids. He is involved in two database projects working towards this goal: the World Echinoidea Database (marinespecies.org/echinoidea) and the Echinoid Directory (www.nhm.ac.uk/research-curation/research/projects/echinoid-directory).
