Sinemydidae is an extinct family of turtles from the Jurassic and Cretaceous of East Asia.[1] Their exact position is engimatic, they have alternatively been considered stem-group cryptodires, but also "crownward stem-turtles" alongside Macrobaenidae, Paracryptodira, Xinjiangchelyidae, Thalassochelydia and Sandownidae outside of crown Testudines.

Genera

[edit]

Material from the Paleocene of California previously attributed to c.f. Sinemyididae is now attributed to macrobaenids.[3]
