Abstract

The Amphicyoninae of the early Miocene from the locality of Tuchořice, the Czech Republic, are represented by three species. Two of them are classified within the tribe Amphicyonini: Paludocyon bohemicus (Schlosser, 1899) as the type species of Paludocyon n. gen., and a large-sized amphicyonid determined as Megamphicyon carnutense (Antunes et Ginsburg, 1977). Dehmicyon n. gen. aff. schlosseri is determined by two small teeth. This new genus has been proposed for the species Amphicyon schlosseri Dehm, 1950 from Wintershof-West and is tentatively included in the tribe Pseudarctini nov. together with the genera Ictiocyon and Pseudarctos. This association of Amphicyoninae provides valuable information on the taxonomy and systematics of this subfamily during the early Miocene, at which time important environmental changes were taking place in Europe, which undoubtedly affected the evolution of Amphicyonidae.

捷克共和国Tuchořice中新世早期两栖动物科(两栖动物科，食肉目，哺乳纲)

捷克共和国Tuchořice地区中新世早期的两栖动物科有3个种。其中两种属于两栖类:Paludocyon bohemicus (Schlosser, 1899)作为Paludocyon n. gen.的模式种，另一种大型两栖类被确定为Megamphicyon carnutense (Antunes et Ginsburg, 1977)。Dehmicyon n. gen. affer . schlosseri是由两颗小牙齿决定的。这个新属被认为是来自Wintershof-West的Amphicyon schlosseri Dehm, 1950，并暂定与Ictiocyon属和pseudoarctos属一起归入pseudoarctini 11 .族。这一组合为该亚科在中新世早期的分类学和系统学研究提供了有价值的信息，这一时期欧洲发生了重要的环境变化，这无疑影响了两栖科的进化。

期刊介绍： Fossil Imprint (formerly Acta Musei Nationalis Pragae, Series B – Historia Naturalis) is an international, open access journal, publishing original papers and reviews of any length from all areas of paleontology and related disciplines, such as palaeoanthropology, biostratigraphy, palynology, and archaeobotany/zoology. All taxonomic groups are treated, including plants, invertebrates, vertebrates, microfossils, and ichnofossils, with a special emphasis on terrestrial and post-Palaeozoic marine biota. We encourage the publication of international meetings as well as special thematic issues. The aim of the journal is to spread the scientific knowledge with no restrictions, and to allow access to it to any interested person. Each article includes information about the date of receiving, accepting and issue.
