'''''Thinobadistes''''' is an extinct [[genus]] of [[ground sloth]] of the [[family (biology)|family]] [[Mylodontidae]], endemic to [[North America]] during the [[Miocene]]-[[Pleistocene]] epochs. It lived from 13.6—5.3 [[Annum|mya]], existing for approximately {{Mya|13.6-5.3|million years}}.<ref>[http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=43648&is_real_user=1 PaleoBiology Database: ''Thinobadistes'', basic info]</ref> |

''Thinobadistes'' and ''[[Pliometanastes]]'' were the first of the giant sloths to appear in N. America. Both ''Pliometanastes'' and ''Thinobadistes'' were in N. America before the [[Isthmus of Panama|Panamanian Land Bridge]] formed around 2.5 million years ago. It is then reasonable to presume that the ancestors of ''Thinobadistes'' [[island-hopping|island-hopped]] across the [[Central American Seaway]] from [[South America]], where sloths in general first evolved.<ref>[http://scienceblogs.com/tetrapodzoology/2007/01/ten_things_you_didnt_know_abou.php Tetrapod Zoology], Scienceblogs, Ten things you didn't know about sloths, by Darien Naish, [[University of Portsmouth]] January 23, 2007.</ref> |
