High diversity of the Ganzhou Oviraptorid Fauna increased by a new “cassowary-like” crested species

Abstract A new oviraptorid dinosaur from the Late Cretaceous of Ganzhou, bringing oviraptrotid diversity of this region to seven taxa, is described. It is characterized by a distinct cassowary-like crest on the skull, no pleurocoels on the centra from the second through fourth cervical vertebrae, a...
