The Shasta ground sloth is believed to have played an important role in the dispersal of Yucca brevifolia, or Joshua tree, seeds. Giant ground sloths ( Megalonyx jeffersonii ) stood about 10 feet tall. Nothrotheriops behaved like all typical ground sloths of North and South America, feeding on various plants like the desert globemallow, cacti, and yucca. Preserved dung belonging to the sloth has been found to contain Joshua tree leaves and seeds, confirming that they fed on the trees. Stratified deposit of subfossil N. The giant ground sloth was an herbivore and preferred living in forests along rivers or lakes. Around 8 million years ago, they migrated into North America, according to the San Diego Natural History Museum. Giant ground sloths preferred forests along rivers or lakes, but they also lived during the Pleistocene period, also known as the Great Ice Age. It was hunted by various local predators, like Smilodon, from which the sloths may have defended themselves by standing upright on hindlegs and tail and swiping with their long foreclaws, like its distant relative Megatherium, as conjectured in the BBC series Walking with Beasts.

The six modern species of sloths are all arboreal, so they are called tree sloths. Fossils of the best-known species, the Shasta ground sloth ( N. The same claws could also been used as tools to reach past the plant spines and grab softer flowers and fruits. Megalonyx jeffersonii was the largest of the ground sloths in family Megalonychidae, reaching the size of an ox when fully grown, said Ken Wilkins, an associate dean for sciences and professor of biology at Baylor University. The Ancient Ozarks Natural History Museum says this mounted skeleton is the most complete and best preserved specimen ever found in Missouri. Giant ground sloths evolved in South America around 35 million years ago. Numerous dung boluses belonging to Nothrotheriops have also been found throughout the southwestern United States and have provided an insight into the diet of these extinct animals. Later, Jefferson was credited with discovering the extinct sloth, which was named Megalonyx jeffersonii. Giant ground sloths were large, lumbering beasts that lived in the Americas during the Ice Age. shastensis ), have been found throughout western North America, especially in the American Southwest.
