摘要

本文描述了巴黎盆地晚古新世Montchenot地区的蜥蜴区系。这些材料可划分为五个主要分支:蛇尾科，蛇尾科(?Lacertidae)，两栖科，蛇尾科(?鳗鲡科和蝇蛆科)。蒙奇诺的组合以小型蜥蜴标本为主，似乎高度分类。捕食可能会产生这种有偏见的组合。蒙奇诺的蜥蜴动物群组成与巴黎盆地两个同时期的地点(MP6) cernay - l -兰斯-兰斯和Rivecourt相当相似。然而，这些动物群在多样性和组成上与同一地区(巴黎盆地和比利时盆地)始新世早期发现的蜥蜴动物群形成鲜明对比。这些差异突出了古新世/始新世过渡对欧洲蜥蜴动物群的影响。

The lizard (Reptilia, Squamata) assemblage from the Paleocene of Montchenot (Paris Basin, MP6)

ABSTRACT Here we describe the lizard fauna from the locality of Montchenot (Paris Basin, late Paleocene, MP6). This material can be allocated to five major clades: Scincoidea, Lacertoidea (?Lacertidae), Amphisbaenia, Anguimorpha (?Anguidae and Shinisauridae). The assemblage from Monchenot is dominated by small lizard specimens and appears as highly sorted. Predation could produce such biased assemblages. The composition of the lizard fauna from Monchenot is rather similar to those of Cernay-lès-Reims and Rivecourt, two coeval localities (MP6) in the Paris Basin. However, these faunas sharply contrast (in diversity and composition) with the lizard fauna found in the early Eocene of the same area (Paris Basin and Belgian Basin). These differences highlight the impact of the Paleocene/Eocene transition on the lizard fauna of Europe.
