Halitherium

Halitherium, an interesting genus of extinct

Sirenia (q.v.), less specialised than their living allies, the dugongs and manatees. Remains have been found in Miocene and early Pliocene rocks in Suez, Malta, Italy, France, Darmstadt. Germany, Belgium, and the Red Crag of Suffolk Halitherium had tusk-like incisors in the upper jaw, as in the dugongs, but its molars resembled those of the manatees. Unlike both existing genera, it had short, broad nasal bones and a rudimentary thighbone and socket.
