Planocrania

Planocrania is an extinct genus of crocodylians.[1] Planocrania was once included in the family Pristichampsidae along with the genus Pristichampsus. Both genera were previously assigned to the subfamily Pristichampsinae within the family Crocodylidae before they were placed in their own family, the Pristichampsidae.[2] Two species are currently known to belong to the genus. The type species, P. datangensis, was named in 1976 from material found from Nanxiong in Guangdong Province, China.[3] A second species, P. hengdongensis, is known from Hengdong County in Hunan Province and was described in 1984.[4]
