Yaverlandia

Yaverlandia (meaning "of Yaverland Point/Yaverland Battery") is a genus of maniraptoran dinosaur.

[1][2][3] it was described as the earliest known member of the pachycephalosaurid family, but research by Darren Naish shows it to have actually been a theropod, seemingly a maniraptoran.

[5] MIWG 1530, the holotype skull, was discovered in 1930, in England and were commented upon by Watson (1930).

[8] When Steel (1969) followed Hulke (1879)[9] in listing Vectisaurus as an iguanodontid, Peter Malcolm Galton (1971) named the fossil as Yaverlandia, which he described as a pachycephalosaurid since the skull of Yaverlandia was different than that of Vectisaurus (Mantellisaurus).

Yaverlandia was found in the Vectis Formation and it would have coexisted with the nodosaur Polacanthus,[14] the neornithischian Hypsilophodon,[14] the iguanodontid Mantellisaurus,[14] an indeterminate euornithopod,[14] the spinosaur Baryonyx,[15] the dromaeosaurid Vectiraptor,[14] the plesiosaur Vectocleidus pastorum[16] and the crocodylomorph Hylaeochampsa vectiana.
