''Epachthosaurus'' (meaning "heavy lizard") was a genus of dinosaur from the Late Cretaceous. It was a titanosaurid sauropod. Its fossils have been found in Central and Northern Patagonia in South America. ==Discovery and naming== The type species, ''E. sciuttoi'', was described by Powell in 1990.〔 The holotype specimen is MACN-CH 1317, which consists of an incomplete caudal vertebrae.〔〔Another specimen, the paratype MACN-CH 18689, contains a natural cast of six articulated caudal vertebrae, the partial sacrum, and a fragmentary pubic peduncle from the right ilium.〔 A new specimen was found recently. The specimen is UNPSJB-PV 920. During field research conducted as a part of the project ‘‘Los vertebrados de la Formación Bajo Barreal, Provincia de Chubut, Patagonia, Argentina,’’ people from the Laboratorio de Paleontologia de Vertebrados of the Universidad Nacional de la Patagonia recovered a well preserved, articulated skeleton of a medium-sized sauropod. This specimen includes a complete, articulated skeleton only missing the skull, neck, four or five cranial dorsal vertebrae, and several distal caudals. The specimen, one of the most complete titanosaurian skeletons known, was referred to the genus ''Epachthosaurus''.〔 A nearly complete skeleton was described in 2004.〔 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「Epachthosaurus」の詳細全文を読む スポンサード リンク
