The Struthionidae and Pelagornithidae (Aves: Struthioniformes, Odontopterygiformes) from the late Pliocene of Ahl al Oughlam, Morocco
Cécile Mourer-Chauviré1, Denis Geraads2

The Pliocene locality of Ahl al Oughlam is situated at the southeastern limit of the city of Casablanca, in Morocco, on an ancient seashore of the Atlantic Ocean. It has yielded a very rich vertebrate fauna (macro- and micromammals, birds, reptiles, amphibians and fishes) including both terrestrial and marine forms. On the basis of biostratigraphy, the fauna has been dated at about 2.5 Ma, which corresponds to the latest Pliocene. The avifauna is very diverse and includes birds belonging to twelve different orders. In this paper we describe only the Struthionidae and the Pelagornithidae. Ostriches are represented by a large-sized form, referred to the extinct species Struthio asiaticus Milne-Edwards, and its eggshells, of struthioid type, are comparable to those of the recent species Struthio camelus, but thicker. The Pelagornithidae, giant marine birds with bony pseudoteeth, are represented by an extinct species of the genus Pelagornis. As far as we know, this species was probably the latest representative of the order Odontopterygiformes.
