Eutatus

Eutatus is an extinct genus of large armadillos of the family Chlamyphoridae. It was endemic to South America from the Early Miocene to Late Pleistocene, living from 17.5 Ma-11,000 years ago, with possible survival into the early Holocene and existing for approximately.

Taxonomy

Eutatus was named by Gervais. The type species is E. seguini. It was assigned to Dasypodidae by Carroll.

Fossil distribution

The fossil remains are confined to Argentina and have been found in the Santacrucian Santa [Cruz Formation, Argentina|Santa Cruz Formation], Ensenadan Miramar Formation, and the Lujanian Luján Formation.

Palaeobiology

The overall masticatory apparatus morphology of Eutatus suggests that it was adapted for browsing. Based on carbon isotope ratios, however, it is thought to have been an herbivore that fed on grasses.
