New Asiatic materials on turtles of the family Adocidae with a review of the Adocid record in Asia

Abstract

This paper presents a review of all known records of turtles of the family Adocidae in Asia, including data from 88 localities. New records of adocids (cf. “Adocus” orientalis, “Adocus” sp. indet. 1 & 2, Adocus sp. indet. 1–4, Shachemys ancestralis, Shachemys sp. indet. 1–5, Adocidae indet.) are described from 14 Cretaceous and Paleogene localities of China, Kazakhstan, Mongolia, Tajikistan and Uzbekistan. Among them the records of Adocidae (“Adocus”) in the Oligocene of Kazakhstan and China are reported for the first time. Reassessment of the published records allows us to change taxonomic status of previous findings from 16 localities. The previously mentioned materials of “Adocus” orientalis from the Upper Eocene of Mongolia are described in detail for the first time. Shineusemys plana and Adocoides amtgai are considered here as species of the genus Adocus, and Mlynarskiella mariani – as Shachemydinae indet.
