Dinosaur Isle, Isle of Wight

The discovery of a remarkable vertebra from the south-west coast of the Isle of Wight allows comparison with a highly specialized taxon of theropod dinosaurs: the Spinosauroidea. We have examined the holotype skeleton of Baryonyx walkeri (Charig and Milner, 1986) and conclude that the new find is closely related to Baryonyx from the United Kingdom and to Suchomimus tenerensis (Sereno et al.1998) from North Africa. We present evidence for a reconfiguration of part of the spinal column of Baryonyx. We also suggest that Suchomimus should be regarded as Baryonyx tenerensis, based partly on the information derived from this important new fossil from the Isle of Wight.
