       The name Pareisactus means‭ ‘‬intruder‭’‬,‭ ‬and this came about from the observation that out of several hundred hadrosaur bones,‭ ‬a single fossil of a scapula‭ (‬shoulder blade‭) ‬belonging to a rhabdodont dinosaur was found.‭ ‬This scapula was subsequently used to name the genus Pareisactus.‭ ‬Like hadrosaurs,‭ ‬rhabdodonts like Pareisactus were plant eating dinosaurs.‭ ‬However,‭ ‬most rhabdodonts are known from the early Cretaceous,‭ ‬but the presence of a rhabdodont bone in a late Cretaceous deposit shows that some rhabdodonts managed to co-exist with hadrosaurs.
