Doedicurus is an extinct armored plant-eating armadillo. Its heavy bony armor and spiked tail club helped protect it from sabre-toothed predators and other hunters. It was part of the South American Pleistocene megafauna 1.8 million to 11,000 thousand years ago.
History
Doedicurus was first described by Richard Owen in 1847 based on part of a tail. Owen originally gave it the name Glyptodon clavicaudatus, the species name meaning ‘club-tailed’. However, nearly three decades later in 1874, Burmeister reclassified the species and gave it a new genus, Doedicurus. This name means ‘pestle tail’ and refers to the similarity of the shape of the tail to the grinding tool of a pestle and mortar.
Doedicurus was the largest of a diverse array of large glyptodonts - extinct relatives of modern armadillos. Remains of Doedicurus have been found in Argentina, Brazil, and Uruguay. It lived relatively recently during the Pleistocene, beginning around 1.8 million years ago, and went extinct just 11 thousand years ago. This means that the first human settlers to South America probably encountered Doedicurus and maybe even hunted it for meat.
