Ganzhousaurus is an extinct genus of oviraptorine oviraptorid dinosaur known from the Late Cretaceous Nanxiong Formation of Nankang County, Ganzhou City of Jiangxi Province, southern China. It was found in a Maastrichtian deposit and contains a single species, Ganzhousaurus nankangensis. It is distinguished by a combination of primitive and derived features.[1]
Phylogeny
Phylogenetic analysis places Ganzhousaurus within Oviraptoridae. Within Oviraptoridae its phylogenetic position is more unstable, with one phylogenetic analysis recovering it as a member of the Oviraptorinae and another recovering it as a more derived member of the group, closely related to "ingeniines"[1][2] However, it also bears some similarities to the basal caenagnathid Gigantoraptor.[1]
Paleobiology
Ganzhousaurus shared its habitat with at least four other oviraptorid species, Jinzhousaurus ganzhouensis, Nankangia jinzhouensis, Banji long, and an as-yet unnamed species. This diversity may have been made possible by niche partitioning, with Ganzhousaurus being primarily herbivorous.[3]
