Synopsis of european neogene freshwater gastropod localities: Updated stratigraphy and geography

Abstract

The last overview of Cenozoic localities with records of freshwater gastropods was provided more than 80 years ago. Since then, a wealth of new information has been published: new localities have been discovered and fundamental changes occurred in regional stratigraphy. In addition, many localities are still attributed to erroneous or outdated stratigraphical concepts even in recent papers. Geopolitical evolution of Europe has, furthermore, led to name changes and confusion regarding the exact origin of samples in collections. Here we provide a fully georeferenced dataset for almost all published Miocene and Pliocene freshwater gastropod localities (2,930), including updated stratigraphic data where possible. This basic update will serve as an essential fundament for any future work related to the freshwater deposits and respective faunas in general.
