plagiosaur

plural plagiosaurs

1. Any of the superfamily †Plagiosauroidea of stereospondyl temnospondyls that lived during the Triassic period.

   Certain short-faced Triassic forms tend to have reduced counts; the brachyopid Batrachosuchus having but 17 maxillary teeth and the plagiosaur Gerrothorax having somewhat over 26.

   One species that deserves special mention is Latiscopus disjunctus (Wilson, 1948) described from the Upper Triassic of Texas. It is the only amphibian of its age that is not a metoposaur, a plagiosaur, a capitosauroid or a brachyopoid.

   In contrast, the amphibian biofacies of Berdyankian time is dominated by mastodonsaurids and plagiosaurs, with much lesser numbers of prolacertiforms, archo-saurs and small cynodonts.
