| Species[1] | |
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 (~ 7,500 BP)[2] and existing for approximately 17.49 million years.[1]
Taxonomy
[edit]Eutatus was named by Gervais (1867). The type species is E. seguini. It was assigned to Dasypodidae by Carroll (1988).[3]
Fossil distribution
[edit]The fossil remains are confined to Argentina and have been found in the Santacrucian Santa Cruz Formation,[4] Ensenadan Miramar Formation,[5] and the Lujanian Luján Formation.[6]
Palaeobiology
[edit]The overall masticatory apparatus morphology of Eutatus suggests that it was adapted for browsing.[7] Based on carbon isotope ratios, however, it is thought to have been an herbivore that fed on grasses.[2]
