Also known as Nan-hsiung, Nanxiong; Planocrania datangensis type

Where: Guangdong, China (25.2° N, 114.4° E: paleocoordinates 26.3° N, 110.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Nongshan Formation, Tiffanian (61.7 - 56.8 Ma)

• ?Paleocene (according to the mammalian remains found from the same horizon). See also Zhang (1984: Subdivision and faunal characteristics of the Cretaceous-Tertiary Luofozhai Group in the Pingling cross-section of the Nanxiong Basin), who provides evidence for it being late Paleocene

•

•Middle Paleocene according to Missiaen (2011)

•

•Wang et al. 2016: Paleomagnetic results from both the Chijiang and Nanxiong basins suggest that the Shanghuan is roughly correlative to the Puercan and Torrejonian NALMA, while the Nongshanian correlative to the early to middle Tiffanian (Ti1– 4a). The Shanghuan and the Nongshanian can be probably correlated to the Early Paleocene Danian and the Middle Paleocene Selandian of the Global Geologic Time Scale.
