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
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
