Phosphatherium escuillei Gheerbrant, Sudre et Cappetta 1996 is a basal proboscidean that lived in Africa during the early Eocene, by 56-55 Ma. [2][3] It is one of the earliest known proboscidean, together with Eritherium azzouzorum from the Selandian (about 60 Ma).[4][5] It was found in phosphorites beds from the base of the Ypresian stage of the Ouled Abdoun Basin, which is best known for its exceptionally rich marine vertebrate fauna.[6][7]
