Macrobaenidae
Macrobaenidae is an extinct family of turtles, known from the Early Cretaceous to Paleogene of Laurasia. Their relationships to other turtles and whether they form a monophlyletic group are controversial. They are typically interpreted as stem or crown group cryptodires, but some more recent analyses have found them to lie outside crown group Testudines. Macrobaenids can be distinguished from other testudinatans by the presence of a carotid fenestra, cruciform plastron with strap-like epiplastra, and a lack of extragulars.

Anatolemys
''Anatolemys'' is an extinct turtle genus in the family Macrobaenidae. Two species are known, both of which lived in the Late Cretaceous. Fossils were discovered in the Yalovach Formation of Tajikistan, the Kulbikin Member and Khodzhakul Formation, Khodzhakul and Bissekty Formations of Uzbekistan and the Bostobe Formation of Kazakhstan. With in carapace length, ''Anatolemys maximus'' was one of the three largest macrobaenids along with Early Cretaceous ''Yakemys, Yakemys multiporcata'' and Paleocene ''Judithemys, Judithemys backmani''.
