Mega Beasts: T-Rex of the Deep (HD Quality) [Part 1/5]

[wererapterps3]

pffft this place is awsome one day in these waters and you'd want to go to hells aquarium for some rnr

[dragonrage122]

am i the only one that thinks dallasaur (or however you spell it) is adorable? of course i think toads are adorable too...

[Chumpupyourbacon]

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

[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.

[wokinghamhessions]

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

[AceofDlamonds]

"I have studied the bite marks left by Liopleurodon on the bones and by matching skull size to tooth marks would conclude that the normal size range was about 5 to 7 meters. Very rough calculations (from plastic models) suggest that the normal weight range was from about a quarter to three quarters of a ton, and up to around 2.5 tons for the biggest animals."

[Narleyproductions]

did u c mega beast terror bird? it completely goes against bbc, in the way that the bird was supreme....help decide whos right

[balamut505]

isnt this predator X

[PrehistoricBeasts]

@balamut505

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...

[vent6547]

@PrehistoricBeasts just telling u tht i took ur advice and typed in what is the proper name for predator x and founf out it is liopleurodon

[EvilCleric]

@shakespearewhiskers5 It's still unidentified. With it's 49 foot length, more than few think it may be a new kronosaurid.

[JewwTroll]

Black booty bitches is soo delicious

[MrRayquazaking]

Wait a minute......Am I watching a mega beast episode that's actually right about a prehistoric predator?.....No I must be dreaming * rewatch episode* Holy shit they finally got it right for once! This calls for a fucking celebration!

Btw thanks for uploading this this gave me a little faith in them for once.

[drzliltito]

holy shit! if i was swimming and one of those came up to me i would of shit in its mouth xDD

[foxhoundnomah]

tx for the upload:)

[PrehistoricBeasts]

@foxhoundnomah

No problem, thanks for watching.

[redcarnotaurus]

I am a lio fan but mosasaurs(tylosaurus, hainosaurus and mosasaurus itself) are more dangerous and would have won 50% or even 60% times if there were to be a battle

[MrMaxlockhart]

whyyyy do people insist they know how aggresive an extinct animal was?

[chobitsgnarlslover]

ya the leopluridon was bigger than mozasaur n way more aggressive...

[PrehistoricBeasts]

@chobitsgnarlslover

I don't want to explain again... just check Liopleurodon on Wiki.

[tyrantking000]

@chobitsgnarlslover walking with dinosaurs got it wrong

[chobitsgnarlslover]

@tyrantking000 how...leo was 45 feet to 50 mozasaur was 45

[tyrantking000]

@chobitsgnarlslover look it up, it was only 20 feet

[AceofDlamonds]

@chobitsgnarlslover

epic fail. Liopleurodon on BBC is not representative of the real thing. The real thing was like 33 feet long. Check.

[wokinghamhessions]

@AceofDlamonds Technicaly Lipleurodon is 25m plus. Plaeotologist did find a lipluerodon only 18m but this was a juvenile. Also a marine repltile has been found with teeth marks that came from a lipleurodon that was at least 25m long. Of corse at an average lipleurodon could of been smaller but as in todays animals and humans you get larger version. ie and average sized saltywater croc is around 5m long but some saltwater crocs have been found ant 7m

[AceofDlamonds]

@wokinghamhessions

nope, I don't know where you got that bad information.....

there is NO Liopleurodon specimen under good review found to be more than 9 meters. Look it up: (Geological Magazine).

the largest L. ferox SKULL to be found was only 4.9 feet.......so by extrapolating based on Kronosaurus and other pliosaurs. THE ADULT Liopleurodon was actually not even 33 feet, but 21 feet!!!

Another pliosaur, assigned, P. macromerus, may have reached 15 meters based on a nearly 3 meter skull.

[wokinghamhessions]

@AceofDlamonds Are you like blind or something! Yes they have found a L. ferox at 18m long in france 1873, not 9m > and why the HELL would u trust Geological Magazine? And an adult lioplreurodon was 25m. and dint you read what i told you that a pleisosaur has been found with teeth marks that came from a lipleurodon that was at least 25m long. Look even if a lipleurodon didnt grow up 25 (which it almost defiently did!) a FOSSIL was found at 18METERS long in 1873 france. Also that was a juvenile

[AceofDlamonds]

@wokinghamhessions

My god, I don't think you understand vertebrate paleontology do you? For one, things since the 19th century are heavily heavily criticised since then.....and new findings change a lot of old views. No confirmed proof of Liopleurodon being that enormous exists. And what 18M "juvenile fossil"? That's clearly outdated and no mention of Liopleurodon being that massive exists in modern paleontology.

What about the ADULT fossil that was 7.1 m I mentioned. That's recent.

[AceofDlamonds]

@wokinghamhessions

In a nutshell, the Liopleurodon myth was refuted a long time ago.

There is certainly no hard evidence of an enormous pliosaur of those proportions...........in fact, the three largest pliosaur fossils in modern paleontology are each around 15 m adults, with the largest skull at 10 feet long........Liopleurodon's skull, by comparison, was only 4.9 feet long.

[wokinghamhessions]

@AceofDlamonds Again didnt u even read what i said! There is plenty of eveidence. A hole skeleton was found which ws 18m, what dont you get about that!!!!!!!!!!!! How is it a myth and dont use the same infomation over agian. Also that dosnt mean all L. Ferox were 25m +. I know im right, theres to much infomation not to beleive it. And why are you so sturbon about it being smaller. surley its better to be big anyway as it makes L. Ferox more intressting.

[AceofDlamonds]

@wokinghamhessions

Show me the link. Why do paleontologists not accept a 25m reptile AT ALL then? Do you realize how long the hell 25 meters (82 feet) is? the skull would need to be an incredible 16 feet long. "NO TAXANOMIC JUSTIFICATION for this assignment could be provided" for a 15 m "young pliosaur" in 2002. Experts suggest that this pliosaur could have grown up to 18 metres (59 ft) long.

So it wasn't even found to be Liopleurodon at ALL. Which makes sense, since L. ferox is EIGHT METERS.

[wokinghamhessions]

@AceofDlamonds Well 18m was what i frist sugessted and you seem to be giving in. Of course i know what 25m long is, im not 2! Alsothe 18m specimen wasnt even fully grown pliosaurs dint stop growing until they died so there absolutly NO reason why L. Ferox could have got bigger. and so what, a blue whale can grow to 33m long. Even leedsecithys grew up to 27m long.And do you absolutly think i believe EVERY lioplreurodon could of got that big. An average would of been mabye 10m if that!!!!"!!

[AceofDlamonds]

@wokinghamhessions

OMG. Stop for a moment. WHERE DID YOU FIND THE 18 M claim? It would be all over Vertebrate Paleontology and would be declared hands down the largest reptile to swim the seas. But it's not......and we know WHY. WHY?? Because there is no estimate that takes this beast past 7.5 m.....I bet you money this "18 M" CLAIM is not based on any good skull extrapolation.

Liopleurodon was 20 feet as an adult.......let's move on already, this has been confirmed for a long time.

[AceofDlamonds]

@wokinghamhessions

I don't think you understand.............a 25 m pliosaur would, but conventional estimates...........require a 5 m head...........now how ridiculous of a size does that make? Liopleurodon ferox, with the largest specimens.......had a 4.9 foot skull.....you are claiming that there is a more than 16 foot skull out there somewhere! No no no no no...............there is NO pliosaur skull recorded by the Journal of Vertebrate Paleontology of a skull that huge....ever.

[wokinghamhessions]

@AceofDlamonds Hahahahaha. I know that a pliosaurs head is a fith of its overal size indicating IF lioplreurodon ever grew to be 25m long then it would have a 5m head And why do you use feet and meteres its seems ridiculous. And how the hell would we know how big piosaurs can get. Thjey grew in water they can grow massive the blue whale is 33m long thats bigger than a lioplreurdion so why couldnt a pliosaur get almost as big. Also i think ure getting a bit stressed.

[wokinghamhessions]

@AceofDlamonds Also if you think that imthink that every single L. Ferox woukld grow up to 25m then ure stupid. There have been unconfirmed reports of a lower jaw found on the Dorset coast measuring as much as 4 meters, which could therefore measure 16 - 20 meters in length, and weigh as much as 20 tons. Oh yeh stop blabbing on about the "Journal of Vertebrate Paleontology" Pliosaurs also never stopped growing so if a pliosaur lived up to say 75 years imagine how big it would get

[AceofDlamonds]

@wokinghamhessions

I believe NO Liopleurodon ferox can grow to 25m. PERIOD. Why are you being such a fanboy about it. The 80 foot L. ferox of BBC legend was just for SHOW! Do you know what the original estimate was?...34 feet.......and even that was too big cause the fossils just didn't imply a length that long.

Show me the link about the jaw...........NEVER did they say it was Liopleurodon....Liopleurodon are small okay. Case closed.

If you don't have evidence of them living 75, don't say it.

[wokinghamhessions]

@AceofDlamonds Fanboy LOLOLOLOL. Im not even refering to the BBC's liopleurodon. I know its not entirely accurate, it was partly for show but it was also based on scientific study.. AND HOW THE HELL DO U KNOW HOW LONG IT LIVED????? And believ me they have found many liopluerodon skeletons around 10m Belive me thats not small.Defeintly stressed. oh where are YOUR sources!!!!!!!!!!!!!!!!!!!!!

[AceofDlamonds]

@wokinghamhessions

Because! the only specimens were have ever found were in the ADULT range of 16-22 feet. The largest jaw ever found from any specimen of the Liopleurodon genus was 4.9 ft. THERE IS NO EVIDENCE OF ANY SPECIES OF LIOPLEURODON REACHING MORE THAN 8 meters.......is that totally clear my man???

IF you don't know how long it lived stop trying to PUSH the idea of a 70 year old reptile......in your view, anything is possible....but never jump to any possibilities without evidence.

[wokinghamhessions]

@AceofDlamonds Puh there IS evidence.................."jus­t provide a link that apparently no paleontologist has observed yet"Because fossils are rare (meaning that it is unlikely we would happen to find the largest example of a particular ancient species), and because pliosaurs, like dinosaurs, did not stop growing with age,] it is certainly likely that very old individuals of L. ferox grew to a size somewhat exceeding that of the largest known specimen, perhaps to 18 meters

[AceofDlamonds]

@wokinghamhessions

What the hell? you're the one who claimed that Liopleurodon ferox could grow up to 25 m and now you're pushing 10 m without citing any source.

The scientific community has the ADULT specimens.....which average TWENTY FEET or so.....seriously...I don't want a flame war and I'm sure you don't either.....just provide a link that apparently no paleontologist has observed yet.........and justify yourself. If it was 18 m or more it probably won't be Liopleurodon.

[wokinghamhessions]

@AceofDlamonds Your are directly avoiding my questions? What make you so certian they can't live that long? sauropods could lie up to 200year and they are not much bigger than a liopleurodon. AND WHER ARE YOUR SOURCES???????????????????????­??????????????????????????????

[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

[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 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

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 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.-

[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.

[AceofDlamonds]

@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

Sessions, the problem is that you want to believe animals would reach these great sizes......but we have no hard evidence of this......Now if you could give me a link to the "4 m" jaws, I'd love to read about it....but I think I may have read about it before......sounds familiar......definitely wasn't Liopleurodon........

[wokinghamhessions]

@AceofDlamonds It also seems howerver that u dont believ any pliosaur could rach thoose lengths. Plus why not believe what life without a little believ. If we never hope to get somewhere we never will. Also i never specified that the jaw was from a Liopleurodon. But it does show if anoputher pliosaur can grow upto those lenghts then why not a liopluerodon? Techicaly ure ignoring what ive said. What about pliosaurs never stopp growing! HUH

[TrueAnimeGoddess]

leuiplureodon is the biggest sea carnivore ever o.o

[Spud13ify]

@TrueAnimeGoddess Not even close. You must have seen "Walking With Dinosaurs" but they greatly exaggerated the size. It was only 30-35 ft. long. I like your name though.

[TrueAnimeGoddess]

@Spud13ify no. they found a 22 foot long skull, just the skull...and they had to place skull to size. read about it.

[Spud13ify]

@TrueAnimeGoddess Ok. Considering scientists figure that a pliosaurs skull is 0ne fifth of it's body length that would make it 110 ft. long and not really possible. Don't go by 1 outdated site. The largest pliosaur found is predator x which had a 9ft. skull and was 45 ft. long. The largest marine reptile overall found is shonisaurus which was a ichthyosaur and was 75 ft.

[TrueAnimeGoddess]

Respond to this video...  oops i meant 12 foot. x3

[sockeyeman]

megalodon wouldwin



[djjosh34445]

@sockeyeman A pod of Orcas could kill anything in the ocean.

[TheGreaterGood80]

Mosasaurs were good at what they did, but not perfect. They were cold blooded and this didn't suit them very well compared to warm bodied sharks which are still alive to this day.

[19a14j5e22a14]

@TheGreaterGood80 : Sharks are Cold Blooded too....Lol hahahah , That's the reason, you don't have them near Antarctic and Arctic Lol :)

[Sunningdalesurvivor]

@19a14j5e22a14 You do get the greenland shark around the arctic circle and they can get 14 feet in length and are top predators of the arctic waters. But there are no sharks around Antartica.

[creatures0blood]

this is like hells aquirium

[MsDjessa]

@creatures0blood It was called that on Nigel Marven´s sea monster´s.

[BLowes45]

Mosasaurs were the no#1 badass aquatic animal of all time. They evolved into the perfect killing machine. If they hadn't gone extinct I don't think that any predatory whale, dolphin or shark would have out-competed them. And yes that includes Megladon. Bigger of course doesn't always mean better. I'd say the mosasaur would be just too quick and agile for the meg to handle.

[Wowsx2bu]

@BLowes45 The megalodon would see it coming from 3 miles away, and has a bite force of 22 tons. The Mosasaurus would be nothing but a bother to something that's larger and actually just as fast. Since the shark's skeleton is made of cartilage the shark would be more maneuverable than the bony Mosasaurus. Try to remember the Brygmophyseter traveled in pods, so the Mosasaurus would end up fighting four or five pissed off sperm whales at the same time.

[MrTobyCure]

@Wowsx2bu We don't have Megaladon's jaws, so we only suspect and guess its bite force. I know it was probably a force to be reckoned with, but Mosasaur was much more successful than the Megalodon because it covered the globe.

[Spud13ify]

@Wowsx2bu Mosasaurs were truly awesome. To dominate the world's seas for as long as they did and even at the end evolve into living in brackish water. After eliminating sharks, they must have starting competing with crocodiles. Amazing

[Wowsx2bu]

@Spud13ify That's true, they are impressive. However, they didn't eliminate all sharks, just the Ginsu shark.

[Spud13ify]

@Wowsx2bu Of course I realize that, but to do that to a shark equal to a great white is saying a lot

[fuckturks2223]

@Wowsx2bu we don´t know the bite force of megalodon

[windowsVD]

@fuckturks2223

True but we have plausible estimate of easily over 24,000 lb.
