Nankangia
Named after Nankang County (now Nankang District), Ganzhou City, Jiangxi Province, China, where the specimen was found
Nankangia is an extinct genus of caenagnathoid oviraptorosaurian dinosaur known from the Upper Cretaceous Nanxiong Formation of Nankang County, Ganzhou City of Jiangxi Province, southeastern China. It contains a single species, Nankangia jiangxiensis. N. jiangxiensis coexisted with at least four other caenagnathoids, including but not limited to Corythoraptor, Banji, Ganzhousaurus and Jiangxisaurus. The relatively short dentary and non-downturned mandibular symphysis of Nankangia suggest that it may have been more herbivorous than carnivorous. Its diet consisted of leaves and seeds.
Diagnosis
- Mandibular symphysis rostral end not downturned, ventral margin of dentary nearly straight
- Neural spines of cranial caudal vertebrae wider transversely than anteroposteriorly, forming large posterior fossa with rugose central area
- Femoral neck extending dorsomedially at angle of approximately 90 degrees to shaft
- Femur and tibia approximately equal in length (ratio 0.95)
- Two infradiapophysial fossae on ventral surface near base of transverse process of dorsal vertebrae
- Pneumatic fossae on sacral vertebrae slit-like
- Large infraprezygapophysial fossa on anterior surface and infradiapophysial fossa on ventral surface of base of transverse process of cranial caudals
- Femur longer than ilium, shared with Yulong and Khaan
- Height to length ratio of ilium 0.36
