China. The type species, Wannanosaurus yansiensis, was described by Hou Lian-Hai in 1977.[2]

Because it has a flat skull roof with large openings, it has been considered primitive among pachycephalosaurs.[2][3] Sometimes it has been classified as a member of the now-deprecated family Homalocephalidae,[4][5] now thought to be an unnatural assembly of pachycephalosaurians without domed skulls.[3] Although its remains are from a very small individual, with a femur length of ~8 centimeters (3.1 in) and an estimated overall length of about 60 cm (2 ft),
