Description
Liopleurodon feroxNamed by: Henri Emile Sauvage, 1873
Diet: Carnivore (Prey included ammonites, fish such as the 50-foot Leedsichthys, sharks such as Hybodus, thallatosuchian marine crocodilians such as Metriorhynchus, plesiosaurs such as Cryptocleidus, and ichthyosaurs such as Ophthalmosaurus)
Type: Pliosaur (short-necked plesiosaur)
Size: 23 feet (7 meters) long and 3 quarters of a ton [the original series made it oversized, up to over 80 feet (25 meters) and over a hundred tons]
Region: Northern Europe (England UK, France, Germany, and Russia)
Age: Mid-Late Jurassic (165 to 150.1 million BC; Callovian to Early Tithonian)
Episode: Cruel Sea
Info: The size of an Orca whale and with teeth twice as long as those of Tyrannosaurus's, Liopleurodon was one of the most awesome marine reptiles during the Jurassic period and was the alpha predator in the vast ancient Tethys Sea in what is now Northern Europe. The arrangement of the nostrils shows that it had a directional sense of smell and like modern sharks, it could sense blood in the water of fresh kills.
On 11/11/2016, I updated it and gave it a fin on its tail as its now believed that plesiosaurs and pliosaurs have

I remember back then, I thought this was one weird looking shark. I know that sounds stupid, but many kids thought this was a dinosaur so who is to blame? Anyways, I always associated sharks as being aquatic animals and dinosaurs as land animals. Nonetheless, I was wrong.

There were no liopleurodon in Russia.Species Liopleurodon rossicus is now Pliosaurus rossicus.

I think that Liopleurodon would've likely weighed at least 1 ton, maybe 2 tons tops. That aside, this is an excellent fact sheet.

The Sea Monsters fact file states that this creature would've been an omnivore. It also states that the size of the original would've dwarfed a living sperm whale.

Okay. I just have something to tell you when you'll do Leaellynasaura. Just think, you know and I know that a white feathered Leaellynasaura would stick out like a sore thumb in the summer forest. So I think you should two, one in summer coat (it's WWD colors) and winter coat. You know do like some snow creatures do like the Arctic Fox , Snowshoe Hare, and Ptarmagin. What do you think?

I think that'll that will be a good idea! Thanks for that advice! I'll remember that!

Your welcome. Can you tell WDGHK I did not mean to offend him. He or she has blocked from making comments. So I can't apologize. If you don't mind.

Ahhhh, I see you made the same changes to the Liopleurodon as you did with the Plesiosaurus.

A 7m Pliosaur would weigh on the order of 3 tons, not 3 quarters of a ton.
To put things into perspective, a 7m Great white shark would weigh 3.4t.
Even without volumetric estimates it’s sort of apparent that a pliosaur would not be just a quarter the mass of a shark of similar length, but it’s not necessary to rely on eyeballing or guesses here, the most reliable mass estimates to go by actually support my point (Based on a 3D-model, McHenry 2009 estimated 10.7m Kronosaurus at 11.4t, based on that we’re getting about 3.2t for a 7m Liopleurodon) whereas I’ve got no clue whatsoever as to who made up the "3/4 of a ton" hypothesis.
WWD obviously oversized it by a vast degree, but this weight figure that’s floating around the internet is pretty ridiculous itself.
McHenry, Colin R. (2009): 'Devourer of Gods'. The palaeoecology of the Cretaceous pliosaur Kronosaurus queenslandicus. Newcastle.

I must also add that McHenry estimated Liopleurodon itself, the specimen used was estimated at ~5.7 meters, ~1736 liters in volume, with a ~1.12-meter skull. Scaling this to ~7 meters gives also ~3.2 tonnes (I get ~3215 liters/kilograms to be more exact).
I agree, the ~750-kilogram mass estimate for Liopleurodon is just nonsense, like those ~3-tonne estimates for ~10+ meter long hadrosaurs. It simply does not work. TBH, it sounds like the kind of thing made up just to spite WWD, the kind of thing that fits something of acepredator 's calibre.

I remember someone in Elementary School called this thing a T-Rex Shark

Are you redoing these for the buildup for Plesiopleurodon?

Well done!! But i think Liopleurodon was a bit bigger.

I recall it being over a ton.

the biggest one was around 4.5 tonnes.

Looks fantastic,
This was my favourite episode in the series (even if the BBC did make the Liopleurodon far bigger than it would have been in life).

But 6 meters İs too small. Maybe 8 to 10 meters seem fit ?

I didn't know Liopluerodon could fly... or blow bubbles in flight . lol
But in all seriousness, your dinosaur art is awesome.
