Rhamphocephalus prestwichi
Seeley, 1880 (type)

Rhamphocephalus ("beak head") is an extinct genus of diapsid from the Middle Jurassic (Bathonian) Stonesfield Slate of Oxfordshire, England.

The type species, R. prestwichi, is known from a skull roof fragment.

Misassigned species[edit]

Pterodactylus bucklandii von Meyer, 1832[1] and Rhamphorhynchus depressirostris Huxley, 1859[2] have been usually assigned to this genus, but a 2012 abstract suggests that the Rhamphocephalus type species is apparently non-pterosaurian, whereas "P." bucklandii and "R." depressirostris are genuinely pterosaurian, and therefore in need of new generic names.[3]
