The common name is "Pliosaurus Funkei" For future reference.
Using Liopleurodon,(which i wouldn't do, That's just me though)as a guide,we can extrapolate exactly how large this thing was. That, and the Svalbard specimen (PMO 214.136 has a skull estimated at 2.0–2.5 m (6.6–8.2 ft), hinting at a possible TBL of 14 or 15 meters. making P. funkei one of the largest pliosaurs described so far.
