On the Finding of Neosuchians (Neosuchia, Crocodyliformes) in the Middle Jurassic (Bathonian) Deposits of the Moscow Region

Resumo

Remains of neosuchian crocodyliforms (isolated teeth, fragment mandibular bone) from the Middle Jurassic (Bathonian) Peski locality in the Moscow Region are described for the first time. The neosuchian from Peski is characterized by well-pronounced ornamentation on the dermal skull bones, and also bicarinate teeth oval in cross section without serration and with triangular conical crowns and fine striation of the enamel. The similarity of Bathonian vertebrate faunas of the Moscow Region, Great Britain, Western Siberia, and Kyrgyzstan is evidence of homogeneity of the vertebrate fauna throughout Laurasia.
