Like its contemporary, Tongtianlong, Huanansaurus ganzhouensis was also found during construction, in this case of a railway station, in the Nanxiong Formation. This turkey-sized oviraptorid was one of many in the Nanxiong, and was likely specially adapted to fill a niche the other oviraptorids didn’t, based on niche differentiation and their variable beak types. As it’s hard to narrow down these animals’ diets beyond herbivore/possible omnivore due to their beaks and lack of teeth, we may never know the exact niche each of them filled. Visually, though, Huanansaurus was set apart by its odd, rectangular skull and unique jaw morphology. It appears to be most closely related to the slightly older Mongolian Citipati, rather than any other Chinese oviraptorid, shedding insight on a possible emigration of Mongilian oviraptorids into China.
