Шаблон:Short description Шаблон:Automatic taxobox

Brachyopoidea is a superfamily of temnospondyls that lived during the Mesozoic. It contains the families Brachyopidae and Chigutisauridae. The earliest records of brachyopids are from the Lower Triassic in Australia. [1] The latest-surviving member of the superfamily is the chigutisaurid Koolasuchus from the Early Cretaceous of Australia.

Description

Restoration of the chigutisaurid Siderops kehli

Some large brachiopoids, such as Siderops and Koolasuchus, grew to lengths of around Шаблон:Convert. However, an unnamed Late Triassic or Early Jurassic brachiopoid from Lesotho in southern Africa is estimated to have been far larger. At an estimated Шаблон:Convert, the brachiopoid from Lesotho is one of the largest amphibians sensu latoШаблон:Ref label ever known.[2] This estimate is based on a single jaw fragment found in 1970 by a French expedition near Alwynskop in Quthing.[3]

Because of its size, the fragment was initially considered to be from a mastodonsaur.[4] However, Several features of the specimen indicate that it is from a brachyopoid. There is a large tusk protruding from the ectopterygoid, a bone of the palate, and the dental morphology is similar to that of other brachyopoids. When viewed from the side, the upper margin of the jaw appears concave.[2] The specimen was redescribed as a brachyopoid in 2005.
