Paleocene proboscideans

Phosphatherium escuilliei, named by Gheerbrant, Sudre and Cappetta in 1996, is a basal proboscidean that lived in Africa during the Early Eocene, about 56-55 Ma. It is one of the earliest known proboscideans, together with Eritherium azzouzorum from the Selandian (about 60 Ma). 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.

Eritherium is an extinct genus of early Proboscidea found in the Ouled Abdoun basin (early Thanetian age), Morocco. It lived about 60 million years ago. It was first named by Emmanuel Gheerbrant in 2009 and the type species is Eritherium azzouzorum. Eritherium is the oldest, smallest and most primitive known elephant relative.
