鋸頜獸屬

鋸頜獸屬（學名：Pristerognathus）是獸孔目獸頭亞目的一屬，生存於二疊紀中期（開匹坦階）的南非F. Abdala, B. Rubidge, and J. van der Heever, "The oldest therocephalians (Therapsida, Eutheriodonta) and the early diversification of Therapsida," Palaeontology, 51, 1011-1024 (2008)，化石被發現於波弗特群（Beaufort Group）地層的鋸頜獸組合帶。

鋸頜獸是種中型合弓類，頭顱骨長25公分，身長被估計可達1.5公尺Stainford Kemp, Thomas(2005) The origin and evolution of mammals p.55。鋸頜獸的頭顱骨狹長，具有相當大的門牙，顯示牠們是肉食性動物，可能會以小型獸孔目、米勒古蜥科為食M. J. Benton, When Life Nearly Died, p. 218, London: Thames and Hudson Co. (2008).。

鋸頜獸目前已有三個種P. baini、P. polyodon、P. platyrhinus。
