Despite the familiar "suchus" (Greek for "crocodile") in its name, Aristosuchus was a full-fledged dinosaur, although one that remains poorly understood. This smallish, western European theropod seems to have been closely related to both the North American Compsognathus and the South American Mirischia; it was initially classified as a species of Poekilopleuron by the famous paleontologist Richard Owen, way back in 1876, until Harry Seeley assigned it to its own genus a few years later.
