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] Based on carbon isotope ratios, it is thought to have been an herbivore that fed on grasses.^[2]

Eutatus was named by Gervais (1867). The type species is E. seguini. It was assigned to Dasypodidae by Carroll (1988).^[3]

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]
