The 'Monster of Aramberri'
The discovery of a huge and substantially complete pliosaur in Mexico hit the press on the 28th December 2002.
It is reported by the media as being Liopleurodon ferox, though this was never mentioned by Dino or Marie-Celine. Although Liopleurodon has been reported from the Kimmeridge Clay most of the specimens are series of vertebrae which cannot be identified unambiguously as Liopleurodon based on our current knowledge of its post-cranial anatomy (which is close to non-existent at the moment), or elements such as a lower jaw which, according to Leslie Noč, are definitely not Lipleurodon. Following WWD, it seems that L.ferox has taken the crown as the biggest and fiercest predator ever (move over T.rex) as as such the archetypical big pliosaur. More about Liopleurodon
It seems that the "small size" is even more inconsistent than the large 25 meter estimate.
