A small, unusual theropod (Dinosauria) femur from the Wealden Group (LowerCretaceous) of the Isle of Wight, England

A complete femur of a small theropod dinosaur from the Wessex Formation (We alden Group, Lower Cretaceous) of the Isle of Wight, England, is described for the first time. In differing from other Wealden Group theropod femora, it augments Wealden Group theropod diversity. The morphology of the anterio r trochanter suggests that it is not of a tetanuran. However, it could repr esent a derived form that has modified typical tetanuran morphology, like t he North American oviraptorosaur Microvenator, which it resembles. Extensiv e pitting on the proximal end implies that it was a pathological or juvenil e individual.
