       Originally named as of Palaeosaurus sternbergii by‭ ‬Leopold Joseph Fitzinger in‭ ‬1840,‭ ‬the fossils was used to establish the Sphenosaurus genus by Christian Erich Hermann von Meyer in‭ ‬1847‭ ‬upon the grounds that the genus name Palaeosaurus had already been used to name another animal.‭ ‬Sphenosaurus was a procolophonid reptile‭ (‬those similar to the type genus‭ ‬Procolophon‭)‬,‭ ‬a type noted for‭ ‬having a squat body and often large horns on the head.‭ ‬Early members of the group seem to have been insectivorous,‭ ‬whereas later members show a shift in dentition form indicating a herbivorous diet.
