Bones of ''Pelorosaurus'' have been found in [[England]] and [[Portugal]]. It was a [[Brachiosaur]], with front legs that were longer than its hind legs. The name has been challenged, and has been the subject of long-lasting dispute. Some palaeontologists prefer the name '''''Cetiosaurus brevis'''''.<ref>Mantell G.A. 1850.
