The Largest Carnivore In Prehistory ( Shastasaurus )

[Hepatomancer]

it's big, but who cares? it fed on soft-bodied crustaceans and cephalopods. Hardly a badass. P.s holy fuck Drakusedge you are a moron.

[josephfitzy270]

And Nothosaurs.

[requiem957]

wtf title says shastasaurus and heres a video about shonisaurus.

[rprshadow]

@requiem957

Reading descriptions, who the fuck does that?

[Sibeveih1]

Biggest is

Megaladon tylosoaur and liopluordon

[RuMpFoRLiFe]

This is so wrong, my d%&k was and is the biggest carnivorous creature. Hahahaha jks, I learnt something new today.

[HeadBangerArtist]

SO IT IS TRUE I COULD NOT BELIEVE IT THE FIRST TIME

[MURB999]

MEGALODON VS SHASTASAURUS

[drakusedge]

liopiopiodon can grow up to 200 - 250 feet in length so ur logic is flawed

[rprshadow]

@drakusedge

Of course it "can", why just yesterday i saw a 300 footer in my fuckin toilet.

You mean "could" not "Can", your grammar is worse than your retarded statement. If you're trying to troll you could at least be creative and try to upset somebody. Not run out into the internet essencially calling yourself a moron.

[scarlocc]

megalodon could grow to 100feet if eyewitness reports are true.

[rprshadow]

@scarlocc

Lol, eyewitness reports.

[XxXThatOneEmoKidXxXx]

@rprshadow Nice Video.

[Vigalante18]

There's always a bigger fish

-Qui Gon Jinn

[puppypupdog2]

its MEGALODON OR LIOPIORDON



[thunderblackbird072]

@puppypupdog2 megalodon is a giant prehistoric shark, liopleurodon is a giant marine prehistoric reptile, are two different animals

[TheGobbler54]

Predator x

[AlabamaSoldier]

Not a bad video.

If you mute it.

[runsaber1]

that must of been michelle 0bama after she fell into a vat of toxic waste and mutated

[MysticMama926]

WRONG

Basilosauros was, because they were 80 feet. OOHHH.

[rprshadow]

@MysticMama926

Direct from basilosauros profile on wiki with reference research to confirm

"Basilosaurus averaged about 18 meters (60 ft) in length, and is believed to have been the largest animal to have lived in its time"

[MysticMama926]

@rprshadow

ANIMALWARZ LIED.

well, I feel stupid...

[MysticMama926]

@MysticMama926

okay, this time i really got it. was it Leedsichthys, right? weren't they 90 freaking feet?

[MultiAsger]

@MysticMama926 lol you are all wrong lieuplorodon grew to around 90 feet and predator x grew to 95

[EvilCleric]

@MultiAsger Huh, then how come the discoverers of Predator X said it was 49 feet long. Oh wait, you're wanking up the creature's length just like BBC.

[josephfitzy270]

@MultiAsger

Duh, Again, Stop Listening To So Much Liars.

[josephfitzy270]

@MysticMama926

I'm Sick Of Hearing Comments Like That Because Of Listening To So Much Mistakes.

[rsuriyop]

Shastasaurus? LOL... was it named after the root beer brand, Shasta?

[zytigon]

For information about similar creatures like the Ichthyosaur & fossils try the superb book ' The ancestor's tale' by Richard Dawkins. For more on evolution try Daniel Dennett, ' Darwin's Dangerous Idea '

[weskerwewe]

megalodon all the way imagine a great white but up to like 70 feet long fucking would beast anything else

[dolphinorcagirl]

In Walking with Dinosaurs it said that Liopleurodon gre to 40 Feet(still like 4 ft to big i know) But it never said 80 ft

Unless by BBC you meant sumin else

Nice Vid though

[LegendaryDollci]

sushi

[AceofDlamonds]

Shonisaurus....estimated at 45 feeet......

Shastasaurus....estimated up to 69 or more feet......both ate meat but were not super monsters

Megalodon....a true macropredator unlike the other two......and also more massive....up to 67 feet maximum and 100+ short tons

Sperm Whale.....average 55 feet and 55 or so tons

Levyitan (Leviathan).....estimated at 17 meters....enormous teeth larger than Sperm Whale's.

Basilosaurus.....who cares, it was skinny as hell

thumbs up so everyone can see. ;)

[EvilCleric]

@AceofDlamonds Except they've seen and recorded bull sperm whales at 67 feet before.

[AceofDlamonds]

@EvilCleric

True......

[TheTupperwareBandit]

But will it blend?

[zOmBiExiLlEr5X5]

yeah but half of them are paintings

[kgeneser]

thats a big fish

[UkMLGplayeR]

Predator X everyone!!!!

[dolphinorcagirl]

@UkMLGplayeR is a fail

[timdeowner]

its aculy a big fat dolphin

[josephfitzy270]

@timdeowner

Shastasaurus Is Actully A Prehistoric Marine Reptile Like Mosasaurs, Itchyosaurs And Plesiosaurs

[GordonFreeMANness]

So... the biggest predator ever is the prehistoric tuna?

[josephfitzy270]

@GordonFreeMANness

No. It Is A Marine Reptile

[62clone]

i know why dinosour wipe out if they still alive now well be eaten that kinda fun isnt it

[MrHu58]

t-rex would pwn it up bad this is an sea creature look at spino for example its an land and sea

[andy765gtr]

to be pedantic, its the biggest in 'prehistory'. to be historical requires literally a written record by humans.

[rprshadow]

@andy765gtr

I adore comments like this, I'm renaming the video accordingly.

[askadetra]

is this song by sound system 007 or something?

[josephfitzy270]

@askadetra

Yeah, Sort Of Like That. WAIT! It Is.

[askadetra]

@josephfitzy270 what? i can't find my comment to see why you responded to me.

[iiKiidCuDii]

its no match for my cracken

[yourgablater]

theres bigger

[sakurashinra]

Youtube has many science

[aznredragon629]

megaladon went up to 50 at least didnt it? maybe im wrong :/

[redcarnotaurus]

I still believe in lio since I think differently to you, but thank you for not spreading the bullshit rumor that b.b.c made lio big for ratings because its and educational show.

[rprshadow]

@redcarnotaurus

Rather it was for ratings or not BBC still promoted misinformation for the sake of prestige. Any information of creatures like these is subject to change and new discovery so you can't blame them for being wrong, but they spent ALOT of money and made alot of bold claims on unconfirmed "facts".

[redcarnotaurus]

@rprshadow I agree.I think it definitely was b.b.c`s opinion and alot is changing around us. It`s alot touger since predator x and pliosaurus were discovered

[galwaypeters2]

@rprshadow true they did catch flak for the lioluredon breaching to kill the small theropod, but liopluredon did fill a niche simmilar to modern marine predators (they used a killer whale as the example) and decided to give it simmilar behavior

your right that these things do change, i mean in 93 when jurassic park came out only a few knew that velociraptor had feathers

[rprshadow]

@galwaypeters2

Further more velociraptors are not as large as those depicted in Jurassic park, the animal depicted is called the Utahraptor.

[Allopexx]

@rprshadow Utahraptor is 8 m long. The animal depicted in Jurassic park was the Deinonychus.

[Allopexx]

@rprshadow Utahraptor is 8 m long. The animal depicted in Jurassic park was the Deinonychus.

[rprshadow]

@Allopexx

Is that so? I haven't looked it up in some time but i have published texts which point out the animal depicted was the Utahraptor, if it in fact has been changed to another animal yet again that further illustrates my previous point.

[Allopexx]

@rprshadow Yeah. Deinonychus is 2m high and 3 m long(depending on where you get your information). The same dimensions as that of the velociraptor in Jurassic park. Utahraptor was only discovered during the making of Jurassic park and believed to be 7 to 8m in length: twice the size of Deinonychus. I notice Wikipedia has a very small depiction of Deinonychus, but other sites say it is even bigger and my book I have here "Collins Dinosaurs, The ultimate guide to prehistoric life" talks about the

[Allopexx]

@rprshadow continued: animal in jurassic park as most likely being the deinonychus.

[EvilCleric]

@Allopexx Indeed, that's what Jack Horner suggested they refer to them as such but basically the movie's crew thought 'velociraptor' sounded cooler, the fact the creature itself is turkey-sized be damned. Thankfully science saved them when the Utahraptor was discovered and they latched onto that immediately.

[darththeo]

In this video, biggest only refers to longest ... ignores mass all together. And so much bad biology.

[rprshadow]

@darththeo

Considering animals like this are EXTREMELY vague in their details and can change from month to month in their approximated size and proportions i can only assume you're fucking retarded.

Case in chief; When i made the video the animal was known as the Shonisaurus, since such time the specimen i was referring to has been re-identified as the "Shastasaurus" expecting detailed assumptions of proportions when research of it is in such short supply is nothing short of ignorant.

[darththeo]

@rprshadow The only retard is you. First, you missed my point, you buffoon. Nice to see you easily leap to conclusions consistently though. Second, longest =/= largest by default, you need to factor in other traits too. Using your logic, the python is bigger than the African Elephant because it is longer. Third, you stated by bad biology when you stated what you think it ate. Clearly, you have a hard on for this thing.

[rprshadow]

@darththeo

What you fail to realize is theres NO WAY to accurately estimate the weight of any prehistoric sea creature based on fossil record alone without making a bold assumption of its bodily make up. Fat, muscle, blubber, there are a variety of materials that can accumulate on a sea creature reasulting in a DRASTICALLY different literal weight. Land creatures can be speculated based on the bones capacity to hold weight which applies differently in water than land, case in point, whales.

[darththeo]

@rprshadow You are now underestimating things, severely. No estimation is accurate, even with land animals, you fool. However, there is data, and information to go off of. Also, you are making an assumption this creature was a PREDATOR, its beak is TOOTHLESS. That is a huge assumption too, that you are taking to be factual. It is like saying the Whale Shark is a predator because it is related to predator sharks. This could be something that just drifts around eating plankton.

[danyeo]

Oh Jesus, a prehistoric animal arguement. LOL. A modern day Sperm Whale can grow 70 feet long and probably weighed more than these prehistoric predators.

[johnchittock]

you could kill a beastie like this with 50's - 60's weaponry. bit of sonar and a nuke then happy days river runs red... and al that from a little hairless monkey :D

[johnchittock]

MANKIND the greatest predators nature ever spawned! with a brain you dont need brawn you have technology...

[Spnozilla]

Liar! Liopluradon is the largest carnivor ever to exist on this planet and so bigger then Megaladon. Also what BBC said about how long it is not over estimated reptiles are not like mammels their fot they keep growing through out thir lives so an old enough Liopluradon CAN! reach 80ft probabaly bigger then that to!

[rprshadow]

@Spnozilla

Actually no, You're thinkin of indeterminate growth, Which exists in fish. Most reptiles DO have determinate growth like mammals. Case and point, of all species on earth today Indeterminate growth exists only among fish species. Not reptiles, which all have consistant points at which they stop growing. Even sea turtles.

[Spnozilla]

@rprshadow So waht?

[rprshadow]

@Spnozilla

So Leopleurodon was a reptile. Stupid.

[Spnozilla]

@rprshadow So was Shastasaurus idot.

[Spnozilla]

@rprshadow so was Shastasaurus stupid.

[erickamos666]

@rprshadow ooooooooo u owned him!!!!

[blakedienst]

@rprshadow your a derp megalodons grew bigger then 75 and had a average of 70 it would still kill what your speaking of.

[MetalScull]

@blakedienst

Man, what are you talking about? Megaladon grew max 50 feet, maybe few feet longer, so it's surely not 75 or 100 feet. I wonder there you heard that idea about his 75-100feet long

[darththeo]

@rprshadow Crocodiles have indeterminate growth and there are evidence that it existed in a lot. Just because growth slows =/= determinate growth.

[blakedienst]

@Spnozilla sorry your wrong the megalodon was the biggest carnivore it had a maximum of over 100 feet in growth, it has over 3 tons in square inch of its bite and it would tottaly kick the little bitchs ass.

[Spnozilla]

@blakedienst wow wait a minute their! I could belive this Shastasaurus thing but I have read and watched enough Megaladon stuff to know that it grew to a maximum 40ft and possibly 50ft but a 100ft s way to big and almost totally impossible for that shark okay Liopluradon can beat a Megaladon okay just deal with it and face facts.

[blakedienst]

@Spnozilla liperoderon didnt have as great of speed and bite strength as the megalodon. the megalodons but strenght was 2.6 tons per square inch the megalodon had NO predators and im sure its killed many of these liperoduns all the stuff that was a good meal for the megalodon AKA the wahles moved to the artic and the megalodon's starved. sory your wrong and the megalodon could grow to 100 feet im sure it happend a few times.

[Spnozilla]

@blakedienst Prove  it!

[Spnozilla]

@blakedienst Dude Liopluradon and Megaladon didn't live at the same time man. Also When fully grown Liopluradon had no predators to. And prove that it grew to a 100ft.

[blakedienst]

@Spnozilla th average lenght for megalodon's was 75 feet i saw it on the discovery channel you calling them liars?

[Spnozilla]

@blakedienst I also herd from both the history channel and the discovery channel that Liopluradon was the biggest predator ever discovered and I didn't call them liars!

[Spnozilla]

@blakedienst Liopluradon was bigger then Megaladon okay and I rest my case.

[blakedienst]

@Spnozilla i realized my mistake i was thinking of some other gay animal XD but the megalodon would destroy this thing cause it has more speed its bigger in width wich means its organs are larger so its got a better chance of surviving and it has a bigge buite force

[Spnozilla]

@blakedienst you may or may not be right about bite force but even if Liopluradon wasn't 80 ft long it is at least the same size right?

[danyeo]

@blakedienst You're sure? HAHA, because you think so? HAHA. Megaladon was nowhere near 100 feet, they have the jaws of these things and have accurate estimations, most of which are 50 feet.

[blakedienst]

@danyeo they are still capable of killing this creature although they lived in diffrent periods we wont ever know.

[AntonySplash]

I like how you were dumb enough to only edit the video title, but not the video description.

Flagged

[rprshadow]

@AntonySplash

why would i bother to do that?

[swainchild]

Liopleurodon is 80 feet long and shoni is 50 feet long.

[haterzhatingit]

sharangasourus was about 250-300ft and weighed about 125-150 tons

[haterzhatingit]

thas tiny

[AnAngryMosher]

Chuck Norris would roundhouse kick this bitch back to the Silurian

[Clusterstorm18]

i tought the egalodon is the biggest

[damenhunt88]

Shastasaurus was a suction feeder so its head should look nothing like the ones in this video

[Skrymik]

Thumbs up if this music gives you a throbbing headache.

[TheRRockMan]

The feeding technique of these titans (Shoni- and Shasta-saurus) has been studied and has been found to be exactly equivalent to that of sperm whales. So it wasn't actually an apex predator. It ate relatively small prey, sucking it in by creating a very powerful inflow in its mouth. It wasn't actually capable of pursuing fast prey and eat any type of animal. It was exactly like a sperm whale today. I can provide links to the studies, if wanted, or you can google for them :)

[UFOJeroen]

still think liopleurodon grew to 25meters the true king of the sea

[Gah9870]

actualy megalodon can get bigger cause they can be from 60 to 120 feet :3

[Racaeel1]

@Gah9870 Megalodon was only 50-60 feet. The largest species were around 70 feet.

[Gah9870]

@Racaeel1 youre right...i think it was 50 to 120 meters or something but anyway...

[NightmareUT]

@Gah9870 Megalodon never grew that big, it was 50-60 feet in length

[Gah9870]

@NightmareUT god i totaly low on info D: its cause i saw a vidd that said it was 60-120...

[NightmareUT]

@Gah9870 Haha it's fine bro that's what learning is for x] but if you think of it. If the blue is the largest organism to live on our planet and its 100 feet long it couldn't really be that big

[Prodecessor981]

i could own that thing with a fork. sushi anyone ^^

[younfellony]

Oh man, imagine your swiming in the ocean checking all the fish and stuff, ! !suddenly you turn around and see a Shastasaurus swiming past you !

(holy Shit)

[blackflames12221]

Shonisaurus= swordfish :O

[Brian19451]

Megalodon?

[Asmallfry]

Liopleurodon was actually 25 meters in length. The reason that it says 6 meters in wkipedia was because of misinformation spread by the internet

[wedingo]

i think the sperm whale is the largest carnivore that ever lived

[JMXXL]

@AwesomeHoneyBager216 so he was the largest carnivore :D

[MsWimsy1]

Crap. I did my speech on prehistoric sea monsters and said that the Liopluerodon was the largest carnivore. I hope that my teacher doesn't find out that I was wrong or I'm screwed.

[redcarnotaurus]

@MsWimsy1 We don`t know which was biggest. just relying on one thing don`t make you right

[DrunkenChicken101]

@MsWimsy1 what you dont know cant hurt you...unless its a murderer who you dont know is behind you

[ttv0]

biggest not most deadly. megaladon.grew close to its size and was bigger stomach

wize

[ttv0]

biggest not most deadly. megaladon.

[Myusernamerulez]

Recent estimates showed that Shonisaurus probably only reached lengths of 49ft. The animal depicted in this video is Shastasaurus, which reached lengths of 69ft.

[rprshadow]

@Myusernamerulez

Thank you for the very rare- "Valid" comment.

[RajaHarimau98]

@Myusernamerulez Rather, Shonisaurus sikannensis (sp?) was moved to Shastasaurus.

[machinegunwhenever]

why cant there just be ONE picture of all these prehistoric animals, instead of 50 showing diffrenent images!!

[JMXXL]

Basilosaurus was up to 80 feet

[supermariolego878]

@JMXXL So? Dude it only weighed seven tons and did not have a very thick body. Therefore, even a MEGALODON would have easily bitten right through it.

[AceofDlamonds]

@JMXXL

no lmao........don't listen to this 80 foot nonsense.

[xlDemonCruxZ]

All you people arguing over which is biggest and what not is nonsense. Megalodon, PredatorX, Shonisaurus, etc were all big predators none the less. THEORIES are practically the only thing we can base things off of. No matter the technology we have now. We still will never know EXACTLY how things were. Until we see the birth to death (or close) of each of these animals will the questions be answered. Now this is just my opinion, you can argue back at me, but.... I rest my case.

[rprshadow]

Pro-tip, if you want a lot of views and comments on a video for years to come. Make a video about an interesting prehistoric animal with all the information and claims that are valid at the time. Then wait for the arguments, which will come in even bigger waves as old information becomes outdated and revised.

[Caponehusky1995]

@rprshadow how doea anyone know for sure liopleurodons max weight/size, hmm??? i think liopleurodon was the biggest carnivore man has found.

[ttoussaint]

@rprshadow

It is getting very hard to trust in scientists / historians information since it seems to change very often. How can we be sure that the information they have right now is true?

[IlovelouisDTV]

holy shit i bet it can even use hyper beam

[FredTaylor28Fan]

Shonisaurus grew at an average of 50 feet, not 70. The largest shonisaurus found was only 69 feet long (found in a remote river bank in Canada). The bones were never released, so there is doubt that the 69 foot dinosaur even existed. They also compared this dinosaur to a dolphin or a big fish.

[MagnusHarvest]

argh, stop using feet:c meters are much better

[FredTaylor28Fan]

@MagnusHarvest feet are more accurate.

[MagnusHarvest]

@FredTaylor28Fan no way.. feet are based on some guys foot in shit days.. meters are based on our number system

[FredTaylor28Fan]

@MagnusHarvest haha... "some guys foot in shit days". thats funny! But what I mean is that if youre talking about a basketball hoop, you would say that its 10 feet... which is more accurate than 3.3 meters.

[Jakethesnake1281]

Shonisaures, chuck norrises close relative

[Xboxzilla]

2:10-2:15 First of all, the young thing is wrong, and the mouth was so thin in those animals that fish and cephalopods were the only things they probably could swallow in one bite.

[overthere86]

Sikanniensis has been reduced of 23 m to 21 m and its skull is around 3 m long.

Also, it was very lightly built, despite its large size and the modern sperm whale would have been bulkier. However, isolated vertebras from S.sikanniensis indicate it could have been even larger than 21 m.

But it is not the largest carnivore ever.

[XxCARNIVOROUSxX]

Shonisaurus averaged 50 ft while the so called 2nd species they found in British Columbia was actually a Shastasaurus. So in conclusion Megalodon was the biggest, best, strongest and all that other stuff.

[SuperMario64N64]

it looks like a spinosaurus

[R3js]

Megalodon is the biggest apex predator ever, after that predator x. What science say.

[tosgem]

you are a ignoranus, megaladon would kill this, it has been found in fossil dropping of megaladon so it obviously eat this animal

[thedbzfanguy8989]

@reba8392 well he is the third biggest after predator x than in top is megalodon actually it wasant apex predator because there other pretadors which in packs but it still ate what it wannet

[reba38491]

I still think Lioplureodon is the largest carnivore to ever exists.

[R3js]

@reba38491

Lio could grow to 33ft.. big ones 43ft.. while predator x 45ft, big ones 55ft.. megalodon 60ft, big ones, upto 100ft... So i have to disagree..

[FredTaylor28Fan]

@R3js Big Megalodons grew up to 75 feet, not 100.

[R3js]

@FredTaylor28Fan Nobody can tell, yet they've discovered theeth and other parts that belonged to an even bigger Megalodon than the one they ensured to be 88feet.. And if read that science actually think that Megalodon was 30times bigger than Great White, ... Average GW = 10-20feet. Would mean that Megalodon average 300-600feet... its a mystery

[FredTaylor28Fan]

@R3js ahh, i see

[thedbzfanguy8989]

No I disagree it is megalodon who is the most ferocious and biggest because of their bite force and speed plus scientist believe it could have grown up to 100 ft

[OnlyRandomful]

If u ask me then lioperodon is biggest creature ever lived on earth

[JELLYBELLY589]

@OnlyRandomful no its not he biggest search it up

[RickRaptor105]

@OnlyRandomful The biggest pliosaur specimens known are 15 meter long. Shonisaurus sikannensis is 23 meters long (though with such thin jaws it probably wouldn´t be a big game hunter like Liopleurodon)

[bitjezeverpeisek]

from where is the pic at 0:50 ? ist really great

[bitjezeverpeisek]

wasnt liopleurodon bigger?

[noah234511]

Well in reality a Meg was 58 average to 72ft maximum and was the apex predater of the sea and although these creatures probably avoided eachother when they fought I would say Meg for bite power agility sences and sheer size

[xXMaDcAsTXx]

What is it eating at 1:00?

[PTphoenixUK]

@xXMaDcAsTXx Nothing, those are two mososaurs, that lived 100 million years after shonisaurs.

[JELLYBELLY589]

@xXMaDcAsTXx a tylosaur

[jvwelder28]

awesome might still be down there who knows we still have 90 % of ocean left to explore

[DaveSustaine]

Apparently it's likely to have fed on smaller reptiles, things like the liopleurodon, although maybe not that specific one because of it's excessive biting power.
