       Teraterpeton was an archosauromorph that much is certain.‭ ‬Beyond this however Teraterpeton was so unlike any other archosauromorph seen at that time that the genus had to have its own family group named,‭ ‬the Teraterpetidae.‭ ‬The‭ ‬jaws of Teraterpeton are notably elongated and thin,‭ ‬kind of like what you might see in a pterosaur or an icthyosaur,‭ ‬though Teraterpeton does not seem to be related to either.‭ ‬The anterior‭ (‬front‭) ‬half of the jaws were toothless.‭ ‬Half way back and extended to below the eye socket‭ (‬another unusual feature for an archosauromorph‭) ‬small sharp teeth grew.‭ ‬The teeth in the upper and lower jaws interlocked with one another,‭ ‬with the cusps of upper teeth fitting into the pits of the lower teeth,‭ ‬and cusps of the lower teeth fitting into the pits of the upper teeth.‭ ‬At the time of writing there is no clear indication as to why Teraterpeton should have become so specialised,‭ ‬though it certainly would have filled some kind of specialist niche within the ecosystem.
