       In‭ ‬1876‭ ‬Richard‭ ‬Owen‭ ‬named a new species of Poekilopleuron called P.‭ ‬pusillus.‭ ‬In‭ ‬1879‭ ‬this species was adjusted to P.‭ ‬minor by Edward Drinker Cope.‭ ‬Then in‭ ‬1887‭ ‬Harry Govier Seeley renamed this species as a new distinct genus,‭ ‬Aristosuchus.‭ ‬However,‭ ‬despite the name‭ ‘‬suchus‭’ ‬which is Ancient Greek for crocodile,‭ ‬this creature was actually a dinosaur.‭ ‬Although the incomplete remains make it difficult to reconstruct this dinosaur,‭ ‬it seems to have been a small compsognathid similar to Compsognathus.
