The Jurassic's Forgotten Apex Predator

- By now, you should know the Allosaurus, thanks to Jurassic World and Walking With Dinosaurs, but you probably haven’t heard of the Torvosaurus. It rivaled the Allosaurus in size and ferocity and here's the kicker, it lived in the same place at the exact same time. It was truly a monstrous carnivore that terrorized prehistoric North America and Europe; unfortunately however, this heavyweight has not gotten as much attention as the Late Jurassic ‘King’, but definitely deserves it, though it has recently received a little bit of love, being featured in Dinosaur Revolution, showing that it could contend with fan favorites like Allosaurus, Ceratosaurus , and maybe even…Saurophaganax.

I wish we saw more of Torvosaurus because not many people know that the Allosaurus seemed to have a bit of competition in its environment.
yeah ceratosaurus

I am curious how Allosaurus became most popular by a huge margin

One aspect that might explain the abundance of Allosaurus and absence of Torvosaurus, might be preservation bias. It seems Torvosaurus preferred an environment which is not very favorable for fossilization. Also, fossils are found in certain areas and layers, but we do not know if and how different biomes interesected throughout these layers. If might be again that the fossil rich layers represent dominant assemblages that was prone to fossilization. Thus the rare occurence of a Torvosaurus popping up in a layer could represent a specimen that had crossed into a different biome either by itself or external forces (e.g. a flood event or river depositition). I think we don't really have good enough data to infer absolute relationships between predators in a broad ecosystem of intersecting biomes as they should be rarer than plant eaters given the pyramid nature of food webs. This is only exacerbated by the preservation bias (or lack thereof) of certain species in certain biomes. If we look at a modern day analogy, the predators of the serengeti, it's not hard to imagine niche partitioning, but also that niches could be linkes to biomes and restrict movement and preservation of certain species. I'm pretty sure that we would find healthy communities of theropods in each biome, each with their own "top dog" although a large theropod is not a universal predator despite totally outclassic modern animals with size, bulk and ferocity. Food webs were most likely as complex back then as it is today. We just don't find enough of these theropods because nature wasn't kind enough to preserve neither their habutat nor their remains; the prehistoric world is not preserved in perfect all-encompassing layers with perfect overlaps between biomes, species and the interconnected food webs criss-crossing the various complex relationships between predators and their environment.
thank for making such a great detailed comment 😊
how did torvosaurus know where the most fossils would be?
This was some good analysis 👍
One of the reasons for its obscurity I think is the fact that there haven't been very many mostly complete skeletons or that not enough different parts of the skeleton have been found to fully understand what it looked like.
Also sounds/spells like Torosaurus & Tarbosaurus.
Meraxes is already "more popular" since it has a mostly complete head, arms, and legs. There's very little of a Torvosaurus body left in comparison.
Allosaurus and Ceratosaurus have a century more of discovery. It just doesn't have the time yet.
@@irmaosmatos4026 Great point.
İ think its just AMAZİNGLY........bland and boring
Slow? I mean. How fast was a stegosaurus?
Guess this still is a remnant of the times when dinosaurs were seen as sluggish and lazy big lizards ...
Faster than the average snail
Torvo was probably the king of Europe. But in North America, it had hard competition.
A territorial dispute between Torvosaurus and a Saurophaganax would have been a sight to behold
Savage Lizard vs Lord of Lizard eaters
Saurophaganax and Torvo I believe lived in different parts of the Morrison but where or if they did they would have niche partitioned with Sauro probably taking on the huge sauropods and torvo probably smaller sauropods and stegosaurus
@@apersondoingthings5689 When water was low due to the droughts they probably had at least fought over the small tussle over the little remaining water. The droughts had probably brought all of the Dinosaurs of the Morrison valley to one singular small lake, because of the low resources animals most likely had been more aggressive.
Finally someone mentiones the existence of torvosaurus. Next do miragaia
next do ambopteryx
nevermind

Not all of us forgotten about that Large Megalosaur. I have some Dinosaur Books showing it. I even recall it appeared on a few known media features. 2 Documentaries & an Anime show.

What was the biggest dinosaur or animal to exist .?
@@mikeking4188 i pretty sure argentinosaurus is biggest dinosaur ever
Not sure why. I think the current narrator is doing a GREAT job.
a cute loli voicesynth would be better
There's a possible third species of torvosaurus located in the Tendaguru Formation of Tanzania, for the time being known as "torvosaurus ingens". Though it's only known for its teeth.
I always hear stuff about Allosaurus and Ceratosaurus, so it was really cool to learn about Torvosaurus.
To me, Torvosaurus seems like the T-rex of the Jurassic. It had thicker teeth and claws, stronger jaws, and a more muscular build than other Jurassic apex theropods, at a cost of speed and agility. It was almost like the bear of its time, using its heavier weaponry to take down tanky prey, most likely stegosaurs because Torvo would have been too robust to maneuver around sauropods safely and jump on to their sides for a bite, and too slow to catch up to speedy ornithopods. Stegosaurs are also slow and robust, and Torvo could use its thick claws to grab a hold of the stegos hide and use its strong jaws to break through their defenses and crack their weaker neck or skull. While Torvo was a more primitive theropod and its jaws were not as powerful as a t-rex, for its time its jaws were probably the strongest, not needing as strong of a bite as a t-rex because torvo didn't hunt the thick headed cerotopsians or the very heavily armored ankylosaurs (stegos were more lightly armored and had slender necks and small heads). It probably was still quite smarter than the very dim-witted stegosaurs as well. I also feel Ceratosaurs would have hunt like big cats, using their sprinting speed and long Sabre teeth to chase down and puncture the tracheas of horse-like Ornithopods until they died of suffocation. Allosaurs were like wolves, hunting in gangs, using their agility to single out and maneuver around sauropods, and using their heavily serrated teeth to continuously bleed out sauropods to death. This seems the most likely to me how each apex Jurassic theropod would have hunted without competing for food all the time with other predators
By that logic, the most fearsome avian predator today is not a hawk or eagle but the common vulture. Maybe the California condor is the most fearsome bird, with a two meter wingspan. Actually, I would not be surprised if a scavenger bird from time to time hunts live prey.
@@raylopez99 Vultures have taken the first bite of a dead human more than eagles and hawks combined
@@raylopez99vultures are predators with weak weaponry and builds meant for endurance flights, something completely unlike torvo. not really a fair comparison to make
@@imlivinginyourceiling Perhaps true; I've heard this argument made about certain Indian Ocean sharks that are scavengers...was it the Oceanic whitetip? Still, I'd not like to be near a huge scavenger...
I will never understand how people still look at a well developed predator like torvo and go "yup, it's soley a scavenger!"
I thought we ditched that flawed concept a decade ago...
Bro Torvo needs more love bro. It’s basically the Jurassics giga. Its huge and terrifying, and I especially loved it in Dinosaur Revolution.
ye its an amazing theropod !!!!!!!!

Where the subject of prehistoric life in general is concerned there is, inevitably, a good deal of educated guesswork involved.

Watching your other videos when this popped up.
Nice.
Noice
Well now you have to do a video for the saurophaganax and allosaurus... COMPLETE THE TRILOGY
what are about ceratosaurus
That was truly an impressive animal - thanks a lot for making and sharing this video!
I think we’ll see some more time to shine. Now that there’s more dinosaur media on the go now outside of Jurassic park we’re slowly getting more accurate and more variety in the mainstream light. Like I was super excited to talk to people who knew what Saurphaganax was. Something that was unlikely even 5 years ago

I've been a dino fan for more than 50 years, but I'd never heard of torvosaurus until now - thanks for this video!
Very cool. I love your videos! 👍🏻

I thought the torvo gurneyi was bigger than it’s North American counterpart since many people have told me and yeah, Torvosaurus needs more spotlight because allosaurus is cool and all but the Torvosaurus should have it’s fair share, great video 10/10
So Torvosaurus was kinda the T-Rex of the Jurassic
I feel like the "it's big and heavy, so it must be slow and also a scavenger" argument is kind of silly. There's ALWAYS something slower. Ntm staying power in the run is important, a difficult thing for slow plated dinos to do in any capacity. The more muscularly balanced wins IMHO.
i love natural history, and i love your channel!
cool dino.
Still more popular than most cenozoic mammals
hehe ur name
Torvo is most likely a hunter as if it was a scavenger it would be extremely time consuming to walk back and forth between carcasses.
If I recall, Saurophaganax came after the extinction of Torvosaurus, allowing opportunity for a new predator taking the large apex predator niche.
Saurophaganax evolved in the middle of Torvosaurus range and the went extinct at the same time and lived in the same place, in the Morrison formation.
@@apersondoingthings5689 The exact extinction point of Torvosaurus is a bit fuzzy but it went extinct around the Kimmeridgean->Tithonian border. Saurophaganax has recently been shown to be solidly within the Tithonian though so it’s likely the two never crossed paths at all. This would make sense as there can’t be two predators that fill the large predator niche without outcompeting one another.
@@IsoSobek the saurophaganax evolved in the Kimmeridgean
@@IsoSobek but the niche partitioned because they died at the same time when there flood plains dried up
@@apersondoingthings5689 I can 100% confirm that Saurophaganax was solidly within the Tithonian. The dating to the Kimmeridgean is extremely outdated. As for niche partition, both animals could not niche partition since they both fed on the same exact animal.
This is the coolest Jurassic theropod
Not because it is large or it can beat Allosaurus or Saurophaganax in a kaiju battle.
Torvosaurus adds to diversity of large predators in Late Jurassic - it's substantial for our knowledge of the past life. It's existence alone is much interesting than the kaiju battle that fanboys imagine. It's just cool to see and learn more about this savage reptile
they were actually quite gentle
@@scambammer6102 acting like they're bloodthirsty monsters is delusional but acting like dinosaurs were "gentle" is even more deluded imo.

@@EarthshakerOnamazu /s
Thanks again my friend!
I still laugh at the camp who seem to think so many of these staggeringly well equipped killers, were "just scavengers".
It's gotten to the point where I no longer trust them on making ANY predation claims.
Yeah, some folks might say, "well, they're scientists and you are not". Well I also have eyes and deductive reasoning ability. When I see a creature so well endowed with weapons of destruction, I can reasonably assume they were quite able to track, take down and kill, a large variety of animals in their environment.
Good video .
Wont be surprised if they ever classified torvosaurus as tyrannosaurid, the skull looks very similar.
I also noticed that when making the video.
@@ExtinctZoo i was like dang, it has a super strong bite and the bone density looks just like tyrannosaurid.
@@skyu777ayala2 If that's true
Then Spinosaurids are tyrannosauroids since spinosaurids are classified as related to megalosaurids (Megalosauroidea)
I doubt that megalosaurs are tyrannosauroids, maybe their primitive forms somehow diverged from even earlier tyrannosauroids in past....that's much possible.
@@danielcorpuz1873 not saying every megalosaur should be classified as tyrannosaurid. To me the skull shape and bone density is strikingly similar to a tyrannosaurid.
@@danielcorpuz1873 compare a torvosaurus skull with an albertosaurus skull, is way to similar xD maybe there were big tyrannosaurids way before they think they appeared.
The Torvosaurus was the same size as the Gorgosaurus. The Tarbosaurus and Albertosaurus were way bigger than them.
It's about the Jurassic period.
This was very good! 👍👍
Why didnt we get to watch cool videos like this in school? Well...maybe because there was no internet but....
allosaurus species can very impressive in large sizes especially Saurophaganax their bites are slashing like and meant to bleed out their prey, also they run very fast⚡⚡.
So is tyrannosauridae imao t rex →→→ allosauroide
I never heard about it until a few years ago !
Can we ever imagine there intelligence ! It's why I can still sleep.
In the Planet dinosaur show Saurophaganax looked way Bigger than a regular allosaurus cause that species of big al can take down large prey and even some guarded Plant eaters🦬🦬.
How about saurophaganax
Thinking any large theropod was a sole scavenger is ridiculous
_Torvosaurus 'get off my lawn' tanneri_ to the Allosaurus gang on his backyard: NYEEHHH!
Torvosaurus was estimated at 11.4 meters by randomdinos, its pretty accurate,
Allosaurus is around 9 meters and Saurophaganax has been downsized from 12 meters to 10.5 meters
Torvosaurus has been found in almost every continent. It is the true apex predator of the Jurassic.
I don't think so according to Molina-Perez it is around 12 meters long and 4.5 tons. Allosaurs also according to him is around 10.4 meters long. Saurophaganax is still a lot heavier with 4.5 tons to 4.1. His estimates are also pretty conservative than that others putting it around 5 tons and 13 meters
Wrong. Saurophaganax is now 12.4 metres & Torvosaurus still 11.4 meters
Meglosaurus is another overlooked dinosaur.
Torvosaurus Gurneyi was much bigger than 9-10 metres? That’s Tanneri. “Specimens of Torvosaurus gurneyi were measured up to 10-11 meters (33-36 ft) in length and 4-5 metric tons (4.4-5.5 short tons) in body mass” -Wikipedia. There’s also a third species in Germany which could be even bigger. And let’s not forget Edmarka Rex... The most well known size estimations are provided by Molina-Pérez & Larramendi. They estimated T. gurneyi at 11.7 meters in length and 3.1 meters in height, with a weight of 4 tonnes.
They also estimated T. tanneri at 11.9 meters in length, 3.1 meters in height, and 4.1 tonnes in weight
The way they said it was a scavenger cause it was slow makes me remember valley of the T. rex
I love the fact that T rex wasn't mentioned. Let these wonderful creatures stand on their own.
A question I've had for a long time is how strong was its bite? Obviously not as strong as a tyrannosaur, but was it enough to employ tyrannosaur-like hunting strategies? looking at the skull, its clear how much more robustly built it is than an allosaur, so surely it had a more powerful bite. Question is, exactly how powerful?
Problem: we can't say the exact bite force of an extinct animal, Also, insufficient remains for torvo.
A study says it’s bite was 3 times stronger than an American alligators bite
Torvosaurus Gurneyi was way bigger than 9-10 metres? “Specimens of Torvosaurus gurneyi were measured up to 10-11 meters (33-36 ft) in length and 4-5 metric tons (4.4-5.5 short tons) in body mass” -Wikipedia.
“The most well known size estimations are provided by Molina-Pérez & Larramendi. They estimated T. gurneyi at 11.7 meters in length and 3.1 meters in height, with a weight of 4 tonnes.
They also estimated T. tanneri at 11.9 meters in length, 3.1 meters in height, and 4.1 tonnes in weight” -Prehistoric Wiki.
OMG, that HAS to hurt.. 2:57
Sounds a lot like the dynamic was similar to wolves and bears. The wolves being primary hunters and the bears being able to hunt with ambush tactics and also using their size to drive wolves off of their kills.
I aprove of this
Just think of how many animals from prehistoric times that MUST have existed that have either yet to be found or failed to fossilize. I did a quick Google search, and saw that it is estimated that there are roughly 8.7 million species of animals alive today. There has to have been millions of species of dinosaurs that are just waiting to be discovered
Unfortunately most are probably lost forever because they didn't live in an environment that preserved their remains.
Funny enough I am in the picture you took of the skeleton at the museum.
I wonder what the Torvosaurus would look like in Jurassic World Evolution 2...🤔
It looks fast and agile.
well....these overgrown Yard Lizards better not trample my garden again!

He looks like t-Rex just with allosaur hands like if he was t-rex grandpa
I will correct you saurophaganax came several million years after Torvosaurus, Torvosaurus ruled the Jurassic on several continents for a whole 15 million years before it’s eventual demise due to an inland sea that made its climate wet and favorable receding dramatically. Apex predators often suffer the most from drastic climate changes this so Torvosaurus was the first to go, with Torvosaurus gone allosaurus and the eventual saurophaganax were quick to fill in the spot as the Jurassic’s last top predators. The megalosaurs regardless of their eventual demise were an extremely successful and powerful group of 4-11 meter carnivores, I know of Megalosaur remains from Normandy belonging to a specimen larger than Torvosaurus that could also just be a Torvo, it has an estimated size of 11.8m and 5.8t, making it the largest carnivore if these estimates are true, saurophaganax’s size is very much up for debate but I’ve seen estimates of it going from only 10.7m and 4.5t all the way up to 13.5m and 6.8t being used. I don’t like discussing about both these apex predators together as people tend to only mention them to pit them against one another, but both are awesome reptiles that deserve respect, I think Megalosaurus itself, should be getting more love by far too, the largest specimen is almost as big as an Acrocanthosaurus, let this first ever discovered theropod dinosaur get its love for once.
the saurophaganax evolved in the middle of the torvos range. They both died out at the same time of 145 million years ago. Saurophaganax evolved to become the biggest predator and the killer of the biggest sauropods such as maraapunisaurus, barosaurus, and supersaurus thus its much bigger sizes and rarer status.
Now saurophaganax weighs 7 tons and is 12.4 m long

The extinction of the dinosaurs took place 66 million years ago due to the impact of a small asteroid on the globe, which led to a major disaster that ended with the complete extinction of a number of living organisms, including dinosaurs.
The video is on a late Jurassic dinosaur. The KT extinction happened in the late Cretaceous. There were multiple extinction events throughout the Mesozoic period. One in the Triassic, one in the Jurassic, one that marked the difference between the early Cretaceous and late Cretaceous, and then finally the KT extinction that you are referring to. This dinosaur happened to die in the Jurassic extinctions long before the KT
If Allosaurus is a Jack-of-All-Stats, and Ceratosaurus is the Small-But-Still-Deadly sprinter, then Torvosaurus would be the Mighty-Glacier brawler, specializing on herbivores of similar size to it.
Anyone else want a future episode of Prehistoric Planet centered on the Morrison Formation?
"dryosaurus" is the dried dinosaur that was so dry that all its flesh flaked off like sand.
torvosaurus had bigger teeth and a stronger bite than epanterias and sauro along with being the same size with roughly the same sword like claws. that is enough to dethrone those two giant allosaurs as the veritable king of the late jurassic.
Epantrias isnt valid and saurophaganax was bigger.
Imagine they're 2 storeys high above us! We're just a small snack ya!
No way.. scavengers dont have teeth like that! Say what you will, that bad boy was a hunter!!
Not forgotten by those who know....
I love how some people think these large dino, including t rex, were mostly scavangers....how dumb is that? Find a known scavanger and look how large they are? Most are tiny and i think its just dumb to think these massive creatures were jist picking up dead stuffs.

If I’m being honest, Torvosaurus deserves the title of “Lion of the Jurassic”. Biggest predator in a savannah-esque ecosystem, rarer than their smaller competitors but far more powerful, and partially because Max’s Blog-o-Saurus made a pretty convincing case for Allosaurus having the title “Hyena of the Jurassic”.
Too slow to catch prey...it shared the habitat with sauropods and stegos, i think it was fast enough
I'm so tired of arguments over whether large therapods were hunters or scavengers. Its basically paleontological clickbait. Pretty much all large meat eaters now will scavenge when they can, and hunt when they have to. Most past large predators likely did the same. Scavenging's easier and safer when its an option. But you don't have to be fast to hunt if your prey isn't- and sauropods (the main large herbivores for most of the age of dinosaurs) were not. And those teeth, claws, and bite were certainly capable of killing large prey.
