Thinobadistes is an extinct

mya, existing for approximately 5.4 million years.[1]

Thinobadistes and

island-hopped across the Central American Seaway from South America, where sloths in general first evolved.[2]

Description

Two specimens of Thinobadistes have been estimated to weigh 948 kg and 1066 kg each.[3]

History and taxonomy

The first reported discovery of Thinobadistes fossils came in 1887 when in Pleistocene deposits in

Texas Panhandle and Withlacoochee River.[6][5] Some of the younger and larger fossils were put into a new species, Thinobadistes wetzeli, which was also based on an astragalus found in Hemphillian deposits of the Withlacoochee River, Florida.[5]

Fossil distribution

Fossils of Thinobadistes segnis have only been found at 2 sites, both

Texas Panhandle.[5] Fossils from an unknown species were found in the youngest Thinobadistes-bearing deposits at Coffee Ranch in the Texas Panhandle.[5][7]
