In Depth

       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.
