Abstract

Themilk dentition of the three known small-sized European species ofHyaenodon (Hyaenodon rossignoli – Eocene,Hyaenodon filholi and H. exiguus – both Oligocene) is described in detail, especially DP3, DP4 and the dp3 and dp4. Interspecific differences in the morphology of these teeth are noted.Themorphology ofHyaenodon filholi is similar to that of Asian andNorth American species and thus suggests this species is an Asian immigrant. According to this study, Hyaenodon exiguus is more distantly related to North American and Asian species than H. filholi. The presence and evolution of a European lineage in the Oligocene is evidenced for the first time.

欧洲渐新世小型hyaendon (hyaendontidae，哺乳动物)的乳齿形态——欧洲hyaendon谱系的证据

详细描述了欧洲已知的三种小型Hyaenodon rossignoli(始新世)、Hyaenodon filholi和H. exiguus(渐新世)的乳齿，特别是DP3、DP4和DP3、DP4。注意到这些牙齿形态的种间差异。其形态与亚洲和北美的hyaeendon filholi物种相似，因此表明该物种是亚洲移民。根据本研究，与北美和亚洲的Hyaenodon exiguus的亲缘关系比H. filholi要远。在渐新世首次证实了欧洲谱系的存在和演化。

期刊介绍： Palaeontographica Section A publishes peer reviewed results of studies on palaeozoology, paleoecology and biostratigraphy. Its large paper format provides sufficient space for large tables, illustrations, photographs and Palaeontographica’s renowned plates. Published contributions span all areas of palaeozoology, i.e., systematic, phylogenetic and ecological aspects. Careful peer review ensures the high quality of the papers, covering localities all over the world. Many landmark papers in palaeozoology and biostratigraphy were published in Section A of Palaeontographica. This includes numerous lavishly illustrated monographs of certain groups of fossils and stratigraphic ranges. These monographs, are typical for Paleontographica papers, characterised by numerous highest quality plates and are printed on special high quality paper for excellent reproduction of picture plates.
