Italosiren

Italosiren is an extinct genus of early dugong from the Early Miocene (Aquitanian) Libano Formation in northern Italy.
Classification.
It was originally classified as a species of "Halitherium", "H. bellunense", but was eventually recognized as closer to the dugong than to "Halitherium schinzii", necessitating erection of the new generic name "Italosiren".
