Erm...'eBay' (Wikipedia?) says this about Liopleurodon:
"L. ferox, with a 1.5 metres (4.9 ft) long skull, would realistically be approximately 7.5 metres (25 ft) long. An exceptionally well-preserved skeleton of L. ferox is on display in the Institut und Museum für Geologie und Paläontologie der Universität Tübingen in Germany. This specimen is around 4.5 metres (15 ft) long. Fossil remains of another specimen identified as L. ferox have been excavated from an Oxford Clay formation near Peterborough. This specimen has been estimated to be 6.39 metres (21.0 ft) in length with a skull length of about 1.26 metres (4.1 ft) and is regarded as an adult individual. An adult L. ferox would have averaged 5–7 metres (16–23 ft) long."
Other large specimens that have been tentatively associated with Liopleurodon have either not been described yet (eg. 'Predator X') or have since been allocated to genera other than Liopleurodon - in the case of the 'Oxford mandible', Pliosaurus.

Your link doesn't say 15 or even 18 meters, what it does say is: New research on pliosaur anatomy has cast doubt on Tarlo's hypothesis for estimating the size of pliosaurs and revealed that pliosaur skulls were typically about one-fifth of the total body length. L. ferox, with a 1.5 metres (4.9 ft) long skull, would realistically be approximately 7.5 metres (25 ft) long. An exceptionally well-preserved skeleton of L. ferox is on display in the Institut und Museum für Geologie und Paläontologie der Universität Tübingen in Germany. This specimen is around 4.5 metres (15 ft) long.[10] Fossil remains of another specimen identified as L. ferox have been excavated from an Oxford Clay formation near Peterborough. This specimen has been estimated to be 6.39 metres (21.0 ft) in length with a skull length of about 1.26 metres (4.1 ft) and is regarded as an adult individual.[11] An adult L. ferox would have averaged 5–7 metres (16–23 ft) long.[9] Notice the last sentence averaged 5-7 meters. Didn't you read my link? www.plesiosaur.com/plesiosaurs/liopleurodon.php I'm afraid I'm going to have to agree with Horridus on this.

From what I remember, Liopleurodon (of any species) is more like circa 7-9 metres maximum; The largest Liopleurodon skull indicates an animal about 5-7 meters long. www.plesiosaur.com/plesiosaurs/liopleurodon.phpThat we have no reason to believe ever existed. A 50ft tall human would be freakishly large too. But like a 12 m Liopleurodon, such creatures are pure fiction. Neither of those are Liopleurodon, nor have they ever been suggested to be so by paleontologists. This is a case of fanboys thinking genus Liopleurodon=suborder Pliosauria. Kronosaurus was 9-10m long. That's leaving aside the bigger, inaccurate mount. Kronosaurus was nearly twice the size of Liopleurodon. Given undescribed fragments of other species, and given Kronosaurus, Liopleurodon was a pipsqueake.

I didn't say that they were - quite the opposite actually! Unless, er, you were just adding to what I said. I didn't mean to imply that 'Predator X' is a Liopleurodon species at all (at the moment it hasn't even been assigned to anything!). Must admit I plucked the figure of 7-9 metres out of where the sun don't shine. Having checked it a bit, 5-7 metres is more like it. Fair point about hypothetical pliosaurs - I was just indulging the fan Also: Stoneage in 'agreeing with me' shock!

In fact preditor x was thought to be a liopleurodon species, the same with pliosaurus.

No no no im just saying that at first they thought the 12m long pliosaurus was a liopleurodon, but the teeth were different, that explains the liopleurodon being 12m!

If Pliosaurus and Liopleurodon were though to be the same genera, then they would all be Pliosaurus (I'm pretty sure that name came first). And since PredatorX (was it found in the 90s, when every brand had an 'X' to demonstrate it's extemehood ;D?) has not been formally described or named--it can't be counted among the verifiable statistics. Once there is published data, use it, but if not, there has been no professional vetting of the information given. And a National Geographic special doesn't count.

Look what up? "Predator X" (I hate typing that, I really do) is yet to be described. It has never been allocated to the genus Liopleurodon (or any other genus for that matter). Which is what sbell said...

I find your avatar text interesting, lio99 - by top predator do you mean most efficient and best at surviving? Because the lineages of all three (liopleurodon, megalodon, and "mosasaurus") were all alive at the same time, and which one died out first...? I know, not really relating to the subject at hand; but looking at the thread title and then the text in his avatar made me have to say something!

Cordylus - why did you give Mosasaurus scare quotes? en.wikipedia.org/wiki/MosasaurusPlesiosaurs and mosasaurs died out at the same time, and yes, sharks are still with us.
