Sinemydidae is an extinct family of turtles from Cretaceous to Paleocene deposits in Asia and North America.[1][2] 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.
