Palaeoamasia is an extinct genus of embrithopod mammal. The type species, Palaeoamasia kansui (Ozansoy 1966) is represented in Eocene deposits of Central Anatolia. There are two other genera in the family: Hypsamasia and Crivadiatherium.
Palaeoamasia was previously described as the oldest and most primitive of the arsinoitheriids; its teeth are lower crowned than those of Arsinoitherium but still bilophodont[2] and its skull lacked horns. Embrithopod fossils have all been found in lignites that formed in swamps and lakes, corroborating the interpretation that all related genera were semiaquatic. Crivadiatherium, a closely related genus, has been found in Romania.[3]
Ozansoy 1966 described the genus, and Ozansoy 1969, Şen & Heintz 1979, and Kaya 1995 have studied it.
