The lower jaw of Sunosuchus thailandicus, a mesosuchian crocodilian from the Jurassic of Thailand
£1.00
A nearly complete lower jaw is described of the longirostrine mesosuchian crocodilian Sunosuchus thailandicus BufTetaut and Ingavat (1980), from the Phu Kradung Formation (early Jurassic) of north-eastern Thailand, and the affinities of the genus are discussed. The jaw is large and robust, with a long symphysis, and each dentary contains about thirty teeth. Despite the unusually elongated mandibular symphysis the genus is referred to the Goniopholididae rather than to the Pholidosauridae, on the basis of the skull characters present in the Chinese species S. miaoi Young (1948). Sunosuchus, however, is in some respects morphologically intermediate between the Goniopholididae and the Pholidosauridae.
