''Glyptotherium'' is an extinct genus of glyptodontid, a group of extinct mammals related to the armadillo living from 4.1—1.5 Ma (AEO). The genus is considered an example of North American megafauna, of which most have become extinct. ''Glyptotherium'' may have been wiped out by climate change or human interference.() Like its living relative, the armadillo, ''Glyptotherium'' had a shell which covered its entire body, similar to a turtle. However, unlike a turtle's shell, the ''Glyptotherium'' shell was made up of hundreds of small six-sided scales. Some species grew up to six feet long and its armor weighed up to a ton. Remains of ''Glyptotherium'' species have been found in tropical and subtropical regions of Venezuela, Central America, Mexico, and the southern United States from Florida and South Carolina to Arizona. There is no direct evidence of humans preying on the North American glyptodont. ''Glyptotherium'' was named by Osborn in 1903, assigned to Glyptodontinae by Downing and White in 1995 and to Glyptodontidae by Osborn (1903), Brown (1912), Carroll (1988), Cisneros (2005) and Mead et al. (2007). ==Gallery== Image:Glyptotheriumm.jpg|Restoration Image:Glyptotherium texanum.JPG|''G. texanum'' skull 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glyptotherium」の詳細全文を読む スポンサード リンク
