Halitherium taulannense, nouveau sirénien (Sirenia, Mammalia) de l'Éocène supérieur provenant du domaine Nord-Téthysien (Alpes-de-Haute-Provence, France)

Abstract

Halitherium taulannense nov. sp., a new Upper Eocene dugongid, is described on the basis of a well-preserved cranium and mandible that belong to different specimens. It represents the earliest species of an Oligocene and essentially European genus. It comes from the ‘Alpes-de-Haute-Provence’, in southeastern France. It provides much information about the cranial morphology of an Eocene dugongid and diversification of the first sirenians during Eocene time.
