Nothrotheriops is a genus of Pleistocene ground sloth found in North America, from what is now central Mexico to the southern United States. [1] This genus of bear-sized xenarthran was related to the much larger, and far more famous Megatherium, although it has recently been placed in a different family, Nothrotheriidae. [2]
The last ground sloths in North America belonging to Nothrotheriidae, the Shasta ground sloth (Nothrotheriops shastensis), died so recently that their dried subfossilized dung has remained undisturbed in some caves – such as the Rampart Cave, located on the Arizona side of the Lake Mead National Recreation Area – as if it were just recently ...
Nothropus is an extinct genus of ground sloth of the family Nothrotheriidae, endemic to South America during the Pleistocene epoch. It lived from 0.781 mya —12,000 years ago existing for approximately 0.769 million years .
Trackways preserved in New Mexico (probably dating from 10 to 15.6 thousand years ago) that appear to show a group of humans chasing or harassing three Nothrotheriops or Paramylodon ground sloths may record the scene of a hunt. The tracks are interpreted as showing seven instances of a sloth turning and rearing up on its hind legs to confront ...
Unfortunately, the bulk of sloth species that once roamed the earth -- some of which grew to be the size of elephants -- cannot say the same. Long ago, there Sloths were once as large as elephants

[8] Excavators also found the dung, backbone, claws and reddish-brown hair of the now-extinct ground sloth (these and other bones from the cave are held by the ...

Among the sloths, Paramylodon, Megalonyx, and Nothrotheriops are three of the four genera recorded in North America, with Eremotherium being known only from the eastern part of the United States. However, Paramylodon represents by far the most abundant ground sloth at La Brea with over 70 individuals, and 30 skulls alone are notable among the ...
