       Protosuchus is a member of a‭ ‬group of reptiles whose descendants would eventually go on to become the modern crocodiles that we know today.‭ ‬Teeth of one jaw can be clearly seen to fit into special notches of the opposite jaw,‭ ‬and the posterior portion of the mouth was wider than the front which allowed for a more versatile and powerful set of jaw closing muscles.‭ ‬However,‭ ‬Protosuchus seems to have been a terrestrial animal suited for hunting on land rather than in the water.‭ ‬The eyes were placed on the sides of the skull rather than the top‭ (‬modern crocodiles peer at their prey while only exposing the eyes and nostrils above the water‭) ‬and the legs were longer than later more modern forms to allow for more efficient locomotion on land.‭ ‬As a predator,‭ ‬Protosuchus probably competed with early dinosaurs such as Coelophysis.
       A bit of trivia‭ ‬about Protosuchus,‭ ‬when first described by the famous American palaeontologist Barnum Brown the holotype specimen had been named Archaeosuchus.‭ ‬However it was soon learned that this name had already been given to a genus of synapsid by the South African palaeontologist Robert Broom,‭ ‬hence the reason for the name change.
