Metaxytherium is an extinct genus of dugong that lived from the Miocene to the Pleistocene. Its remains have been found in Africa, Asia, Europe, North America, and South America.

Paleobiology

Metaxytherium lived in coastal waters and inland waterways, and there is evidence that they were preyed on by sharks.^[2]

Species

There are eight species of Metaxytherium recognized as valid: M. albifontanum, M. arctodites, M. crataegense, M. floridanum, M. krahuletzi, M. medium, M. serresii, and M. subapenninum.

The genus Thalattosiren Sickenberg 1928 was once thought to be distinct from Metaxytherium, but is now considered a junior synonym of M. medium.^[3]
