Pristerognathus was a medium sized predator that lived in South Africa during the Capitanian stage of the Permian. Another species of Pristerognathus, P. minor, was later re-described as a new genus, Pristerognathoides. However since this time there has been occasional speculation that Pristerognathoides should be made a synonym to Pristerognathus.
