Doedicurus clavicaudatus, pestle tail, was a prehistoric glyptodont with a mace-like clubbed tail. Doedicurus lived during the Pleistocene until the end of the last glacial period, some 11,000 years ago. It lived in North and South America and was the largest known glyptodont. Glyptodonts were heavily armored cingulate xenarthrans related to modern armadillos that evolved during the Miocene in South America. The extinction of the glyptodonts coincided with the arrival of early humans in the Americas and evidence suggests that these humans made use of the animal's armored shells.
