Anthracobunid

They superficially resemble the Moeritheriidae in both size and cheek tooth morphology, but lack their characteristic tusks. They were relatively small, ranging in size from 1 to 2 m in length. They are known only from fragmentary remains (mainly teeth) from Eocene deposits of the northwestern part of the Indian subcontinent. Recently excavated fossils with well-preserved jaws and teeth demonstrate that these animals were either perissodactyls or else part of a more primitive sister group to the perissodactyls. The anthracobunids were probably amphibious and lived in marshy environments. Analyses of stable isotopes and long bone geometry suggest most anthracobunids fed on terrestrial vegetation, but lived near water. The same cladistic analyses that prompted their new placement also imply that the semiaquatic marine desmostylians, another putative non-African afrotherian group, were closely related to the anthracobunids.
