Redescription of the soft-shell turtle Rafetus bohemicus (Testudines, Trionychidae) from the Early Miocene of Czechia Chroust, Milan Mazuch, Martin Ivanov, Martin Alba, David M.. Hernández Luján, Àngel Trionyx Rafetus Bohemia Most Basin Břešt'any Burdigalian Trionychinae Czech Republic The taxonomy of the soft-shell turtle Rafetus bohemicus (Liebus, 1930), family Trionychidae, subfamily Trionychinae, is revised based on new and previously mentioned material (including the type material) from the Early Miocene (Burdigalian, MN 3) sites of the Most Basin, Czechia. Given that the diagnosis was so far based only on plastral elements, here we focused on the cranial material and combined our study with previously published data on postcranial elements. 3D models of the skulls derived from CT scans allow us to provide the first complete skull description of R. bohemicus, including several new cranial diagnostic characters of the species. Our results not only enable the distinction of the trionychid genera Trionyx and Rafetus, both recorded from Central Europe during the Early Miocene, but further allow us to provide an emended diagnosis for R. bohemicus. We confirm the conclusions of a previous study according to which Trionyx pontanus, T. preschenensis, T. aspidiformis, and T. elongatus are nomina dubia. R. bohemicus from Břešt'any (MN 3) represents the oldest record of this genus in Europe as well as the oldest occurrence of the genus. 2023 Article https://ddd.uab.cat/record/281935 urn:10.7717/peerj.15658 urn:oai:ddd.uab.cat:281935 urn:oai:pubmedcentral.nih.gov:10387236 urn:pmid:37525660 urn:pmc-uid:10387236 urn:pmcid:PMC10387236 urn:articleid:21678359v11e15658 eng Ministerio de Ciencia e Innovación PID2020-117289GBI00 Agència de Gestió d'Ajuts Universitaris i de Recerca 2019/BP-00154 PeerJ ; Vol. 11 (July 2023), art. e15658 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
