}}Eremotherium is an extinct genus of ground sloth of the family Megatheriidae, endemic to North America and South America during the Pleistocene epoch. It lived from 4.9 mya —11,000 years ago existing (as a genus) for approximately {{Mya|4.9-0.011|million years}}.[1]E. rusconi reached a length up to 6 m (20 ft) and a weight of more than 3 tonnes.[2] TaxonomyEremotherium was named by Austrian paleontologist Franz Spillmann (1948) and was assigned to Megatheriinae by Gaudin (1995); and to Megatheriidae by Franz Spillmann (1948), Carroll (1988) and Cisneros (2005). Fossil distributionFossils have been uncovered from Volusia County, Florida, Chatham County, Georgia; Berkeley County, South Carolina; Espirito Santo; and Pedra Preta, Brazil; Tarapoto, Peru (giant form); Rio Canas, Ecuador.[3] SpeciesE. eomigransE. eomigrans was named by De Iulis and Cartelle (1999). E. eomigrans was assumed to have been restricted to Florida, as most fossil specimens have been recovered from that area. However, in 1993, another specimen was recovered in North Carolina.[4] It lived from 4.9 mya—300,000 years ago ({{Mya|4.9-0.30|million years}}).
E. laurillardiE. laurillardi, sometimes called the Panamerican ground sloth, was named by Lund (1842). It was previously considered a nomen dubium by Hoffstetter (1952), Gazin (1957) and Paula Couto (1979); it was recombined as Eremotherium laurillardi by Hoffstetter (1954), Cartelle and Bohorquez (1982), Cartelle and De Iuliis (1995) and Hulbert and Pratt (1998).[5][6] Fossil distribution was from the southern U.S. to Brazil. It lived from 780,000—11,000 years ago ({{Mya|0.78-0.011|million years}}). Fossil distribution
