Adapis is an extinct adapiform primate from the Eocene of Europe.[2][3][4][5][6][7][8][9][10] While this genus has traditionally contained five species (A. magnus, A. bruni, A. collinsonae, A. parisiensis, and A. sudrei), recent research has recognized at least six morphotypes that may represent distinct species.[6]Adapis holds the title of the first Eocene primate ever discovered. In 1821, Georges Cuvier, who is considered to be the founding father of paleontology, discovered Adapis in fissure fillings outside of Paris, France.[3] Given its timing and appearance in the fossil record, Cuvier did not recognize the primate affinities of Adapis and first described it as a small extinct pachyderm; only later in the 19th century was Adapis identified as a primate.[6][8]
