Predator X is a specie of Pliosaur.

[shakespearewhiskers5]

@PrehistoricBeasts is predator x liopleurodon

[PrehistoricBeasts]

@shakespearewhiskers5

No, they're different species.

[shakespearewhiskers5]

@PrehistoricBeasts tnx for telling me but then who is predator x

[PrehistoricBeasts]

@shakespearewhiskers5

There is a site called Google...

[Chumpupyourbacon]

I am glad that these creatures are dead . Or else i doubt i ever want to go swimming in a beach.

@wokinghamhessions

I cannot find your "4 meter" specimen anywhere......and of the reliable sites I've come across, such as Plesiosaur(dot)com, the Dorset "4 meter" skull has not been confirmed at all..........

If true, it WOULD equal a possible 16-20 m animal......although it wouldn't be Liopleurodon.

[AceofDlamonds]

@wokinghamhessions

And I'm telling you for the fourth time that your measurements are wrong.

The mandible itself was 2.87 meters........okay? The actual SKULL was estimated to be "in excess of 3 meters", meaning a little more than 3 meters.....x that by 5 based on Kronosaurus, and we get 15 meters....that's still very big.

The L. macromerus (assigned in 1959) was obviously flawed, and Smith and Walton fixed it back to Pliosaurus macromerus in 2004.

The animal found in Dorset had a 2.4 m skull.

[wokinghamhessions]

@AceofDlamonds I totally understand and for the 5th time are you even listening to my comments!!! And the skull WAS 4m not 2.8. Yes animals are always classified wrong but it doesnt mean they all are. And there was a skull at 3.6 meters in length, was at one time classified as Liopleurodon macromerus. (When the mandible was described, it was originally assigned to Stretosaurus (as Stretosaurus macromerus). The genus Stretosaurus later became a junior synonym of Liopleurodon.-

@wokinghamhessions

I don't think you understand what I am saying man. The classification of 1959....was refuted easily and changed back to P. macromerus. Do you want a list of all the obsolete taxon I can think off the top of my head? When researchers find a mistake, they fix it. Hell, we have people classifying animals wrong TODAY......let alone 50 yrs ago.

And check your facts, the jaw was 2.8 m...the skull estimated to be more than 3 m (9.8 ft) x 5 = 15 m or 49 feet, give or take a foot.

[wokinghamhessions]

@AceofDlamonds And when i seached "liopleurodon" i came up with NOTHING on sciencedirect so send me a link

[wokinghamhessions]

@AceofDlamonds OH MY GOD are you even listinig to my comments? obviosly not! And it was 4m not 3! And whats 4 x 5............. yes 20m. And how cares how long ago a fossil was found! Some of the best discoveries where 100s of years ago.

[AceofDlamonds]

@wokinghamhessions

Continued........in addition, it is worth noting that the study of the 2.9 m jaw dubiously assigned to Liopleurodon you are referring to is over 50 years old.......so we should be aware how wrong that was. The more recent 2004 study from Smith et al reclassified it on the basis of further research on known specimens in the 21st century.

You can find the abstract on ScienceDirect.

[AceofDlamonds]

@wokinghamhessions

By any chance, are you referring to the 2004 study on that specimen? Smith and Walton re-classified it as PLIOSAURUS macromerus, and they got it right.

The BBC exaggerated the size significantly......there was no precedent for such a huge size. The BBC also got the size of Leedsichthys wrong. The broadcast revealed the pressure of releasing such a dazzling show in a time when there wasn't enough peer review on the findings yet.

BTW, 3 meter skull = about 15 m individual.

[wokinghamhessions]

@AceofDlamonds A mandible on display in the Oxford University Museum of Natural History, estimated to be over 3 meters and to have come from a skull perhaps 3.6 meters in length, was at one time classified as Liopleurodon macromerus. (When the mandible was described, it was originally assigned to Stretosaurus (as Stretosaurus macromerus). The genus Stretosaurus later became a junior synonym of Liopleurodon.and also this is where the BBC gottheir liopluerodn from
