Eremotherium (from Greek for "steppe" or "desert" "beast": ἔρημος "steppe or desert" and θηρίον "beast") is an extinct genus of giant ground sloth in the family Megatheriidae. Eremotherium lived in southern North America, Central America, and northern South America from the Pliocene , around 5.3 million years ago, to the early to ...
Megalonyx (Greek, "great-claw") is an extinct genus of ground sloths of the family Megalonychidae, native to North America.It evolved during the Pliocene Epoch and became extinct at the end of the Late Pleistocene, living from ~5 million to ~13,000 years ago. [3]
In many species of Megatherium, the lower jaw is relatively deep, which served to accommodate the very long hypselodont (evergrowing) teeth, [20] which are considerably proportionally longer than those of other ground sloths. Like other ground sloths, the number of teeth in the jaw is reduced to 5 and 4 teeth in each half of the upper and lower ...
Here's a cool fact from The Sloth Conservation Foundation: without sloths there wouldn't be any avocados. "The extinct giant ground sloths were some of the only mammals that had digestive systems ...
Ground sloths are a diverse group of extinct sloths in the mammalian superorder Xenarthra. They varied widely in size with the largest, belonging to genera Lestodon, Eremotherium and Megatherium, being around the size of elephants. Ground sloths represent a paraphyletic group, as living tree sloths are thought to have evolved from ground sloth ...
Closeup of hand, showing claws Closeup of skull. Megatheriidae is a family of extinct ground sloths that lived from approximately 23 mya—11,000 years ago. [3]Megatheriids appeared during the Late Oligocene (Deseadan in the SALMA classification), some 29 million years ago, in South America.
Life restoration of the related ground sloth Megalonyx. The postcrania of Eucholoeops are represented by limb elements. The humerus is large, with a proximal portion (that close to the body) that is subcylindrical and widen into a flattened distal portion (that far from the body): this condition is seen in all non-mylodontid sloths.
Xibalbaonyx is an extinct genus of megalonychid ground sloth known from the Late Pleistocene of Mexico. Three species are known: X. oviceps and X. exiniferis from the Yucatan Peninsula and X. microcaninus from Jalisco. The genus is named after Xibalba, the underworld in Maya mythology.
