Prorastomus sirenoides (meaning "broad jaws at the front."[1]) is an extinct species of primitive sirenian that lived during the Eocene Epoch 40 million years ago in Jamaica.

Description[edit]

While modern sirenians are fully aquatic, the 1.5 metres (5 ft) Prorastomus was predominantly terrestrial, judging from the structure of its skull. Judging from its crown-shaped molars and the shape of its snout, it fed on soft plants.[2]
