Welcome to another SV-POW! world first: the first ever outing (to my knowledge) of a photo of BMNH R5333, an articulated set of two-and-a-bit titanosaur caudal vertebrae. These vertebrae come from the famous Wessex Formation of the Isle of Wight: they are from the Lower Cretaceous, and specifically from the Barremian.
