Synonymous with what?  The only older sauropod genus from Early Cretaceous
Europe is Pelorosaurus (assuming oxoniensis is made the neotype of
Cetiosaurus by the ICZN), and it's not comparable AND from the Hastings
Beds, not the Upper Weald Clay.  I see no reason to assume Oplosaurus is a
synonym of Pelorosaurus.
