Gorgosaurus Preferred Drumsticks

- Tyrannosaurs became among the most dominant predators ever during the late Cretaceous, pushing out almost all smaller predators from their environments. A new, incredible fossil of a young Gorgosaurus may show part of the reason why, with its prey still preserved inside.

Me ordering wings🤝 Gorgosaurus
Shouldn't it be drumsticks?
@@alisav8394 i mean- i was thinking the drumettes because wing places always give you a mix of wings and drumettes and im very biased rofl
I love fossils that show direct evidence of behavior.
as soon as i heard that it had specifically targeted and ate the legs of the Citipes, it unironically sent chills down my spine, because the exact same type behaviour is seen in modern peregrine falcons. you can always tell when a bird was a falcon victim because the chest will be untouched, but the legs will be torn clean off. The current theory is that they avoid the chest because bacteria in the organs of their prey could get them sick, and hawks eat it anyway because of their stronger stomachs. It says a lot about the strategy (and potentially intelligence?) of the animal.
Maybe! It may also just be a behaviorally biological thing, where they get more nutrition from the legs due to the way their gut microbiome works.
"I like thick thighs and I cannot lie" - Gorgosaurus, probably
It's like how human children exclusively eat nuggets
Gorgo wants his chicken tendies
Tyrannosaurs were very intelligent and it doesnt surprise me that they were also very adaptable when it comes to prey items throughout their lifespan. Maybe this was also a part of why they outcompeted other predators.
Its super interesting that they changed in body shape, especially the head, when they grew up. The juvenile rex in lost world is a classic design and from todays perspective would have had an elongated head and would be slender built instead.
Also the alioramini look a lot like theyve retained a lot of juvenile features. Almost as if they stopped changing shape when aging. Is that the case?
Tyrannosaurs DIDN’T outcompete other predators. They rose to dominance AFTER all other large predatory theropods in the Northern Hemisphere had been wiped out, so there was nothing for them to outcompete.
Also, LARGE THEROPODS IN GENERAL underwent this sort of niche shift as they grew up. This is NOT unique to tyrannosaurs as way too often assumed.
Yet another example on why Gorgosaurus is my favorite tyrannosaurid, it's just such a cool animal and this new discovery was worth the wait; seeing a juvenile tyrannosaur hunting not 1 but 2 of it's preferred prey is just badasss
Hope you all have a great day.
Alberts were cool too! Both often overlooked.
It's funny that this therapod wanted drumsticks, as we mammals today eat a lot of drumsticks from therapods
I mean, technically it was also eating theropod drumsticks. Gorgosaurus is just like us fr
Great video! Tyrannosaurs are a bit of an ecological mystery. They must have been pretty amazing in life.
Ty for another great study vid. Any chance you’ll do anther Tyrannosaur genus like the Albertosaurus? I always learn so much from you guys. Best channel on TH-cam!!!
It depends what comes out about them, and what out schedule is like when that paper comes out. The most recent one from today for example is happening when we're working on other content, so probably not as a full video.
I always imagined the prehistoric forests had baby dinosaurs running around everywhere and had young meat eating theropods after them something overshadowed by the larger adult dinosaurs. My imagination is becoming closer to the truth now.
need a "gorgosaurus gorging on gorgonzola" sticker lol
Amazing stuff. Thanks Raptor Chatter.
Makes sense, the legs of theropods are extremely muscular so thats where a lot of the meat is, and like modern birds of prey it mightve avoided the areas with a lot of bones and bad organs
Wrote this before I finished the video lmao, yes exactly what you said theropod legs are very thick like their tail
Thank u so much,I can use this for my game concept I’m working on,it’s a game that simulates what life could have been like in the “dinosaur park formation”.btw how do I differentiate the two tyrannosaurus hunting styles?
Go by how they're shaped, even t Rex would switch inches growing up. Most tyrannosaurs have round bodies and long legs and would chase after smaller prey, then larger ones like albertosaurs and daspletosaurus probably could take on mid sized prey with their ridiculous bites. It isn't until you get to trex where they specialize in megafauna like shantung and ceratops
@@zmerk253 don’t u mean tarbo instead of tyranno?and I’m trying to differentiate forgo and dasp,but thanks anyways
I mean gorgo
@@KOurboi gorgo and daspleto have a lot of similarities, and their teeth are practically identical. but daspleto is notable more robust and generally larger, so they'd likely tackle the same general types of animals, just different size brackets. it is possible that gorgosaurus was a pursuit predator where daspleto was an ambush hunter due to how long-legged gorgo is in comparison, but that's my own speculation.
@@casualsoapmuncher561 thank u that makes things a lot easier
Im always taken aback when reminded of how leggy juvenile tyrannosaur were
Me too, me too.
The whole idea that ontogenetic niche partitioning allowed tyrannosaurids to dominate and outcompete other predatory theropods is flawed for two reasons: a) ontogenetic niche partitioning likely was a theropod thing in general (we even have direct evidence for it in Allosaurus, which also follows the pattern of juveniles being much more cursorial than the adults), and b) tyrannosaurs only took over the Northern Hemisphere following the demise of all other large predatory theropods from the Northern Hemisphere; their rise was the effect, not cause, of said other theropods dying out.
I did comment on it being possible in others, but wasn't aware of the evidence, what's the case for it in Allosaurus? I do agree, and think there will be something more about the Mid-K climatic events which will be more to blame in the future
@@RaptorChatter
There’s a juvenile Allosaurus specimen that shows significantly more cursorial leg proportions from adults (Foster & Chure 2006), indicating it was hunting small, fast-moving prey compared to the adults.
@@bkjeong4302 One specimen doesn't necessarily indicate a trend. We have way more tyrannosaur juveniles then we have of other large theropods. It's unclear, but right now we just have evidence for tyrannosaurs.
Ontogenetic-based nice partitioning is not unique either in the fossil record or among existing carnivores. Living Komodo Dragons do it, as do most extant Crocodilians. And likely Deinosuchus and Giganotosaurus did as well. It seems to me the most salient factor in determining how extreme this partitioning becomes, is related to the final adult size of a given animal. And of course things like average growth rates, basal metabolism and other parameters.
We also have evidence for it in Allosaurus.
Remember the movie "GORGO"???
Okay, I don't remember it too well, but I'm surprised that there was an actual real dinosaur with a similar name.
This video made me wonder how citipes tasted like. Now I want to eat roasted citipes. Thanks
At that age, they probably did taste at least a bit like turkey/ chicken. Likely a lot of white meat from fast twitch muscle fibers, as opposed to duck, which is more like a red meat because they fly long distances.
I think you meant Mexican gray wolves were reintroduced to Arizona not red wolves
I absolutely did. I actually did a project about them for a class a year or so ago, and am now ashamed I messed it up that much. It's at least right in the script, but I just messed up on the recording. Thanks for the correction!
nice
My favourite dinosaur 😊
So Im a gorgosaurus?😂
Isn't it much more likely that the young tyrannosaurus scared away the adults, and the adults left the children behind, which explains why only fledgling legs were found?
No. In that idea there are presumptions that tyrannosaurs lived in groups, that ovirapotorosaurs lived in groups, and that the young oviraptorosaurs also wouldn't run from danger.
I always love predators hunting different prey as they grew like crocodilians and Komodo dragons. who would like to see a juvenile Barinasuchus chase a Miocochilius.
You try out-evolving a T Rex, doh!
Dinosaurs rock
So would have the adult Tyrannosaurs have hunted and killed the other theropods in a way to limit the loss of juvenile tyrannosaurs?
I imagine they would have just hunted and killed them out of competition, rather than as a way to avoid the loss of their own juveniles
No, because there *weren’t* any other large carnivorous theropods in the Northern Hemisphere by the time tyrannosaurs began their ascendancy.
I'm sure it would have hunted the smaller theropods, but this pattern starts before Tyrannosaurus, and a large individual of a different theropod group would also have hunted smaller tyrannosaurs, so unless there's a very clear mechanism for why one was more successful at hunting the other it's likely that it had to do with other aspects of their relationship to the ecosystem, potentially hunting other prey, or maybe something else.
I've known about this channel for years but I'm only now recognizing how great it really is. It's right up my alley. Oh, the level of insight a 24 hour binge can provide. It puts everything in perspective. I shall never take you for granted again. 🥲
I appreciate this! Good to hear you like the video!
