Tehuelchesaurus (/teɪhwɛltʃeɪsɔːrəs/) is a genus of dinosaur. It is named in honor of the Tehuelche people, native to the Argentinian province of Chubut, where it was first found.[1]

Description

It was a moderately large (possibly 15 metres (49 ft) long) cetiosaur-like

dorsal, sacral and caudal vertebrae, parts of the forelimbs and hindlimbs, parts of the shoulder girdle and pelvis, some rib fragments, and skin impressions.[1]

Tehuelchesaurus is most similar to

centra but without internal chambers) and opisthocoelous centra, unlike in Barapasaurus and Patagosaurus. The length of the entire neck and tail are not known, but based on other proportions (humerus 1.14 metres (3.7 ft) long; femur 1.53 metres (5.0 ft) long; scapula 1.75 metres (5.7 ft) long; ischium 1.01 metres (3.3 ft) long; ilium 1.12 metres (3.7 ft); pubis 94.3 centimetres (37.1 in) long), Tehuelchesaurus was probably about 15 metres (49 ft) long. It was named by Rich, Vickers-Rich, Gimenez, Cuneo, Puerta & Vacca in 1999.[1] The type species is Tehuelchesaurus benitezii (/beɪnitɛziaɪ/), named after Aldo Benitez, who discovered the holotype.[1]
