Based on fossil trackways and the anatomy of its inner ear, which is considerably different from living sloths and more similar to those of armadillos, species of Megatherium, while probably not capable of moving at considerable speed due to limitations of their skeletal anatomy (with one study estimating a max speed of approximately 2.2 metres ...
Little Salt Spring is a feature of the karst topography of Florida, specifically an example of a sinkhole.It is classified as a third magnitude spring. [4] The numerous deep vents at the bottom of the sinkhole feed oxygen-depleted groundwater into it, producing an anoxic environment below a depth of about 5 m (16.4 ft). [4]
[1] [2] [3] Most paleoburrows are likely made by giant armadillos and large ground sloths, depending on their size. [4] Thousands of examples have been identified across South America, mostly in the Brazilian states of Santa Catarina and Rio Grande do Sul. [4] The first paleoburrow was discovered in Rondonia by Amilcar Adamy in 2010. [5]
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 ...
Location Jefferson and Taylor counties, Florida, United States The Page–Ladson archaeological and paleontological site ( 8JE591 ) is a deep sinkhole in the bed of the karstic Aucilla River (between Jefferson and Taylor counties in the Big Bend region of Florida ) that has stratified deposits of late Pleistocene and early Holocene animal bones ...
Scientists have uncovered evidence of ancient humans engaged in a deadly face-off with a giant sloth, showing for the first time how our ancestors might have tackled such a formidable prey.
Eremotherium laurillardi skeleton at the Smithsonian National Museum of Natural History. Eremotherium was slightly larger than the closely related Megatherium in size, reaching an overall length of 6 metres (20 ft) and a height of 2 metres (6.6 ft) while on all fours, possibly up to 4 metres (13 ft) when it reared up on its hind legs.

Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla.It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America.
