E. libyca and an extant manatee by Charles R. Knight, 1907
Size of Eosiren (purple) compared to other Eocene sirenians and a human.

Eosiren is an extinct genus of sea cow that lived during the Late Eocene (later Priabonian) to Early Oligocene (Rupelian).[1] Several fossils have been found in Egypt. It seems like the species E. abeli were contemporaneous with Protosiren and Eotheroides.[1] like them, Eosiren closely resembled modern sirenians. It differs from them by having somewhat larger innominates and possess thigh bones.[1]

Eosiren was first described by vertebrage paleontologist Charles William Andrews in 1902, who distinguished it from the genus Halitherium due to differences in the teeth and mandible.[2] Later that year, Science published a summary of his findings in a collection on advances in zoopaleontology.[3]
