What is "yaverlandia"

Yaverlandia is a genus of theropod dinosaur. Known from a partial fossil skull found in Lower Cretaceous strata of the Wessex Formation on the Isle of Wight, it was described as the earliest known member of the pachycephalosaurid family, but recent research by Darren Naish shows it to have actually been a theropod, seemingly a maniraptoran. Yaverlandia was named from where it was found, Yaverland Point.
