Paleobiology

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