The Hadrosaurs (Duck-Billed Dinosaurs) Were Not Easy Prey

- Hadrosaurs are always being depicted as poor defenseless dinosaurs, only existing to be a free meal for carnivores like the Tyrannosaurus or Allosaurus. However, that notion is slowly changing. Since the time of their discovery, paleontologist have started to think that Hadrosaurs were not all that defenseless and used many tactics to defend themselves and thrive in a world full of giant predators.

As someone who really loves ornithopods, its really nice to finally see a video talking about how great hadrosaurs are.
Hadrosaurs are POWERFUL!
@@jeffreygao3956
Oww yeah, Jeffrey Gao-3956...😏
So perhaps, *is the hadrosaurs are that DARNINGLY powerful* 💪🏻 right then...🤔🧐?
Even deer without antlers will put up a fight when they don’t have many other options left. It’s ridiculous to think Hadrosaurs were completely defenseless during their time.
Personally for me, I think they were alot more defenseless than todays herbivores lol Compared to what predators we have today, they certainly did not fair better lol
@@Kogasengaha_Hishoshi doesnt make sense but ight
@@Kogasengaha_Hishoshi BRUHHHHHHHHH HAVE YOU EVER SEEN A HORSE? A GIRAFFE? A TUSKLESS ELEPHANT? CAMELS?
@@arandomguyonyoutube5460 I don't know, have you seen a rex man handle A horse? A Giraffe? A Tuskless Elephant? Camels? Compared to what predators we have today on land besides Crocodilians/Gators. I think most animals round the world fair quite a bit better than what they had to deal with back then. Sure you have a Spotted Hyena and your occasional Lions. Animals today more often or not can defend themselves if needed and yes more often or not they are meals for Hyenas and Lions. But its not like we have fuckin therapod crocs hunting without really care in the world on land.
@@Kogasengaha_Hishoshi bro you dont get what i mean, i mean that these anmals i listed have no visible weapons no spikes no armor nothing yet they are still very succesful because of their size alone, so why wouldnt hadrosaurs be the same? also the difference between hadrosaurs and ceratopsians is that hadrosaurs had no predators which meant they didnt need any armor to survive, while triceratops had t rex dakotaraptor and other trikes which meant it had to get armor to survive
Thank you for clearing this up. Hadrosaurs aren't just a soft target for theropods. Hadrosaurs are very bulky & could fight back
ain’t you the same dude who thought carnotaurus was a scavenger
@@raptorzilla0710 He is!
I think they fought back with thier weight to try to crush their opponent like sumo wrestlers.
@@kade-qt1zu Yo!!!
@@kade-qt1zu But...then WHAT was hunting big creatures in the Late Cretaceous Maastrichtian Argentine floodplains?
Media often portrays hadrosaurs as fodder animals losing to even raptors 1/50th their weight, yet, because of a single thumb spike, they also portray iguanadon as these one-man predator killing machines.
Not to mention that hadrosaurs had large tails and could possibly been able to knock out a rex with a hit to the head. Or, they could've also stomp on them by rearing up on their back legs and stomping down on them with all their force with the front. Let's not forget that hadrosaurs were pretty smart, just second place in intelligence behind Ornithomimids.
we dont know their intelligence...actually we dont know the intelligence of any dinosaur but its obvious they were enough to use all these tactics to live otherwise they would not be able to function
Their beaks could've been used as well. Hadrosaurs didn't have a duck like beak but instead something similar to ankylosaurs. Combine that with a strong bite force from chewing plants and you have a nasty bite.
do you really think a 10+ animal is standin on their frontlegs to kick or take down something as big as a rex
@@Left_Shoulder yes
@@Slomurr do you think an edmontosaurs can kick like a horse???
Theropod Fanboy: All hadrosaurs were tiny and weak.
Shantungosaurus: Am I a joke to you?
As someone who really loves theropods, even I find it stupid how hadrosaurs are always portrayed as defenseless wimps.
@Red Robotic What are you trying to say?
@@kade-qt1zu Truly a red robotic moment
@Red Robotic then why are they trying to say things about dinosaurs to people
@@parakeetbudgie Exactly people should learn to do their research first instead of pulling crap out of their rear end lol
Hadrosaurs ARE POWERFUL!
Interesting how this latest study supports my chilhood theory and view of hadrosaurs self-defense which has been in my thoughts at least since the beginning of the 2000s. And I'm probably not the only one who came to the same conclusion even before this study. And this is actually much better because now we can use this research to support the theory.
All of these defenses show that hadrosaurs were not the defenses whimps and punching bags they are often portrayed in media
People assume that since hadrosaurs didn't have large osteoderms, giant horns, or spiked tails, they must defenseless, ignoring the various other defenses they had.
@@kade-qt1zu People also think the same about sauropods. They also used to be shown as walking balls of meat especially in Jurassic park when in reality, even a pack of mega theropods would think twice before attacking an adult.
@@wildlifeisthewealthofnatur5457 Well, and *that's just really breathtaking that the sauropods' were an ABSOLUTE UNIT for it's time* right...
Even a capybara or a zebra could put up much of fight. It can be kinda ridiculous to hadrosaurus were completely defenseless against predators. The same also happens with chalicotheres
Capy is chilly lol not defenselessbut chilly
It is great that the Hadrosaurs got some respect in this video. It would have been interesting to see a battle between a large Hadrosaur and a large predator.
If we assume everything in this video is true (seems pretty accurate to me) it’s funny how the ecosystem on earth hasn’t changed in hundreds of millions of years. Edmontosaurus is a wildebeest and tyrannosaurs would have been lions. Still, I think the idea that hadrosaurs were defenceless is outdated, or only partly true. While I’m sure they would have been able to do significant damage to predatory therapods, compared to other species of herbivorous dinosaur they were fairly defenceless. Which does of course bolster the idea that they were able to run long distances
Is the clip at 1:50 from Julian Johnson Mortimer?
I see Edmontosaurus as more like an African buffalo then a wildebeest. Something that’s huge and outweighs its predator. It probably was taller than the average Trex (when standing on its back legs).
Yup it is indeed Mr. Mortimer, he's one of the best and is gracious enough to have a creative commons page.
Edmontosaurus are more like cows or large bovines. Wildebeest are pretty fast and can go up to 45 mph
yes, nearly everything in the video is accurate.
I think a zebra or a horse would be a better comparison to Edmontosaurus and other hadrosaurs than a wildebeest or a cape buffalo, something that can run for long periods of time, has no obvious physical defense features like horns, armor, etc. and also has a powerful kick, and also has hooves on the front feet, just like a horse, so the whole thing about hadrosaurs being defenseless is only partially true, but they would defend themselves when necessary like with a kick or a tail whip, or even rearing up on their hind legs and crushing an opponent by stomping on them with all their weight.
I will ride for Hadrosaurs I will die for Hadrosaurs my top 3 are 1. Olorotitan 2. Edmontosaur annectens 3. Tsintaosaurus
It's hard for me to choose what my number one favorite hadrosaur is, but my three favorites are Shantungosaurus, Parasaurolophus, and Lambeosaurus.
Ajnabia, gryposaurus, and the last one’s close between barsboldia, shantungosaurus, and annectens. Probably annectens though.
March of the Dinosaurs 2011 actually has a Hadrosaur as the main character, & though not a true Hadrosaur Disney's Dinosaur had an Iguanodon as the main character .
With the possibility of Hadrosaurs being herd animals. The Predators that hunted them probably had to make a right ambush. If an ambush fails who's going to say that they are gonna charge and tackle you with thick mass especially with alot protective mothers and they broke your bones... well you're dead.
It is my personal belief that aside from all the adaptations explained here Hadrosaurs could have been even riskier prey. When drawing from modern large herbivores such as Hippos, Elephants, and Rhinos, it's possible Hadrosaurs could have been INCREDIBLY aggressive animals, compensating their lack of built-in weaponry with sheer overwhelming berserker-warrior-rage.
edit: grammar.
Well said about this one hypothesis which you made in your comment right here, Rio Hudson-9612...🧐
So Hadrosaurs and Tyrannosaurs were long distance runners. That would be a cool chase to see.
Not really, Tyrannosaurs were built to walk long distances not run long distances...
@@cro-magnoncarol4017 True, the large Tyrannosaurs couldn't. I doubt the big Hadrosaurs could run too.
@@Salamander128 No, studies have shown Hadrosaurs were surprisingly good endurance runners for their size. They could easily out pace a Tyrannosaur if they saw it coming.
@@Salamander128 Again that's only for walking, Tyrannosaurs were large predators that had massive territories to patrol. They're going to have to be good at walking. Not to mention, good at walking does not equal good endurance runner. For example, Lions walk massive distances everyday to patrol their territories but they're not good endurance runners.
As for the study, I sadly forget where it is but Hadrosaurs were more than capable of out pacing a Tyrannosaur. Fore their size alone was just not enough to fend off a predator that big.
@@cro-magnoncarol4017 Sorry, I have to disagree. The study was on walking and speed walking, that's all big Tyrannosaurs could do. This is, as far as I know, the same for Hadrosaurs. They were limited to walking and speed walking.
There is nothing to suggest Hadrosaurs could move faster than a Tyrannosaur of similar size. So even if Hadrosaurs did "run", which I don't see evidence of, the Tyrannosaurs speed walked faster.
Here at 45:04
m.th-cam.com/video/N967OjUXZMg/w-d-xo.html&t
Palaeontologist Tom Holtz is giving a lecture. It's recent and probably not outdated. He describes Hadrosaurs as not as well adapted for speed as Tyrannosaurs. So it's hard to say who could run(or speed walk actually) for longer. However, evidence does suggest that Hadrosaurs didn't have the same speed capabilities.
Perhaps Hadrosaurs were good at endurance. But to figure out who was better is difficult.
So there is no evidence I've seen for Hadrosaurs being faster. And nothing conclusive for either group being better at long distance.
It was so stupid how people thought hadrosaurs are weak.Large herds plus their size of being as large or larger the their predator plus their beaks makes them hard to kill and hunt.A edmonto would have no problem bitting and stomping a full grown rex
On a different note, which theropod do you guys like better, Gorgosaurus, or Daspletosaurus?
Daspletosaurus, it's actually my 6th favorite dinosaur. Gorgosaurus is such a cool dinosaur too though.
Gorgosaurus is my favorite dinosaur, so…
Daspletosaurus since it's the top predator of it's time. It's also believe to be the ancestor of t-rex
@@mhdfrb9971 evolution is not a linear process, hybridization is an important part of evolution
@@shafqatishan437 no it's not
Thinking the dino was defeneless is purely a stupid thought, one evne deer without antlers will put up a fight when cornered, and judging by the dino's front legs, I am certain it will stand up and much like a bear, throw hands. Plus in a standing position.And before you say anything about a herbivore standing on two putting up its dukes, well Elks and Deer do this when they need to and uh hooves can be sharp.
However I wonder how these animals would perform if they were heavy weight beasts of burden.
Well elephants can kick very well. So a hadrosaur could certainly kick hard. Also just their huge mass a forcefull shove or bodyslam. They where very stable on their feet
Thanks for embracing diversity in units.
A very nice overview. I suspect carnivores preyed on juveniles, or the old and weak. But a really enjoyable video.
Correct me if I'm wrong but aren't iguanadons hadrosaurs? And if so were the thumb spikes not used for self defense as well?
Iguanodon is related to hadrosaurs, but is not a hadrosaur itself.
Iguanodonts are basically just proto-hadrosaurs.
They were either close relatives like antelopes & ibexes are with each other or distant relatives with convergent evolution like antelopes & deer to each other.
Iguanodonts and hadrosaurs were ornithopods
There thumb spikes were for defense to
although a study in 2022 suggested that the largest Edmontosaurus weighed up to 6-7.7 metric tons
I want to add that also most hadrosaurs were usually more heavier than their predators so they probably could’ve shifted their weight onto them or outright crushing them, and also could probably sever the predator’s limbs if small enough with their beak lol-
I feel that people under estimate hadrosaurs compared to other herbivores because they lack the defensive features of anklyosaurs and stegosaurs while not being massive like sauropods.
It's videos like this that make me wonder how stable Tyrannosaurs on 2 legs were compared to Hadrosaurs on 4, especially when the latter outweighs the former. It seems all it would take is one good push.
That's what I've been trying to tell everyone!
Remember friends, hadrosaurs ARE POWERFUL!
I hate how popular media, specifically the Jurassic Park films has corrupted the image of these amazing creatures.
Well said, Astartes-6969...🤔
Perhaps that the *Apple TV+'s 🍎📺 "Prehistoric Planet 🌎🌍🌏" documentary series* was definitely a *pretty faithful, honest-to-reality documentary show about the dinosaurs ever since* all right...
Also, being bit by one would have been no joke.
Yeah-hah, Eri...😵💥💀
Anyone who has ever played the isle will tell you that the Shan is no joke 💀
They were by no means defenceless, their sharp beaks could give nasty bites, they could kick or trample a predator, they could throw their weight around, or they could slam their incredibly muscular tails into their attacker.
T Rex usually weighs 8-10 metric tons, convert to US tons would be around 9-11+ US tons
Even though the muscles suggest more endurance do not forget that Hadrosaurs were lacking the more efficient respiratory system and hollow bones that Theropods had, so in terms of stamina it was probably a more even race than you think.
And?Hadrosaurs couldbite,kick,buck,slam and crush
I feel like you should’ve mentioned the iguanodon, they had a a defence (forgot what it’s called) dagger or blade on their hands or thumbs, since they were sharp, they would’ve easily inflicted wounds on the predators of the region that attempted to hunt them.
and also plugging in the 70% equation meaning the largest possible T Rex would be 15 tons, although the same applies to all dinosaurs.
Is there any evidence of injury’s sustained by theropods that could have been caused by hadrosaurs?
Yall need to watch dinosuar king cuz that show does sooooo much justice for the herbivores a lot more than modern day media lol
I see Hadrosaurs filling a zebra/donkey like niche, and Zebras are very terrifying animals.
I just wonder because of thier size if on they used thier mass to knock over and crush some carnivores like sumo wrestlers.
I mean I better make sure not to think Hadrosaurs are easy targets again
The difference between a 15 to 13m Edmontosaurus and trex wouldn’t have been that different, it’s akin to comparing a zebra to a lion. Not too much defence
Zebras aren't defenseless. One kick can break lion's jaws.
@@ExtremeMadnessX no one said defenceless, learn to read
well some of these points sound weird to me personally like the trampling, yes edmontosaurus was massive but its impossible for a fully grown tyrannosaurus to get trampled, its literally almost the same size as an edmontosaurus, also the horse like rear kick is impossible for any hadrosaur because their front legs are weaker than the rear and on their own there is no way they would support the animal in order to do the motion, not to mention the big tail is in the way unlike horses who have tiny tails so the area is open to hit any predator and tyrannosaurids specifically may have been better adapted for catching up with hadrosaurs because their foot structure is adapted for conserving more energy making them capable of running for longer periods of time a structure that hadrosaurs dont have...but after all thats why edmontosaurus evolved so big next to trex, to use its size as defense so a fully grown one probably didnt even need to outrun tyrannosaurus even more so if they lived in herds
but for every other point i have to agree safety in numbers, fast reproduction rate and stuff are all making sense the whole body could be used for defense probably even pushing the predator or standing on 2 legs in place and use the front to fight after all when your life is in danger you will do anything to live no matter if you got spikes or armor or anything like that
Dude ed farfrom being defenseless
Even a zebra or a horse can fight back, imagine what a Hadrosaur dino would do!
I heard tell that an adult Edmontosaurus on the larger end of the scale could outweigh Tyrannosaurus by almost 5 more tonnes.
I better make not to think Hadrosaurs are easy targets again
I know, man. I died to a single adult teno in The Isle as a cera.
Imagine using one of these on the silk road, or pulling a carriage 😅
Hadrosaurs were the horses of the Mesozoic.
They may seem like they have no defenses.
But they can surely pack a punch if you underestimate them.
I bet many a foolhardy young T.rex has lost its life to an Edmontosaurus on more that one occasion.
the faster maturity rate and the 'less predators' line is ...... illogical
Giant Shant wasn't 13 tons. It was 18+ tons.
Stupid how hadrosaurs, the second largest herbivores are being treated badly even if sauropods smaller than them are seen as a formidable force
Mesozoic Horses!
Hadrosaurs could not front kick there legs were to small for that there back legs could back kick but hadrosaurs weigh to much for that. What they could so is trampel them useing there force while running they can crush there predator. And hadrosaurs can bite but it’s not as hard to kill a Rex
I lovve theropods, but dont underestimate hadrosaurs.
It takes approximately 2-3 T-Rex to take down a grown ass Edmontosaurus.
Yes,their defensive mechanism might be the most inferior out of all herbivores.They didn't have thumb spikes like their ancestors,the Iguanodonts and their tail might be useful for combat but not very effective considering how heavy and dense it is compared to sauropods who has a lighter,hollow tail construction.
But hey,that doesn't mean they can't put up a fight right?😂😂
Ed for example will kick,buck,nite,slamand crush
One T rex can take a edmontosaurus down lmao
🦕🦖🦕
If you can live and even thrive alogside the tyrant lizard king... I wouldnt say you are fully defenseless..
Nene moyang bebek ya ini doi
Imagine an angry, testosterone filled sauropod💀
I'm not saying they were ridiculously easy to kill. They were preferred targets to predators because they didn't have horns, claws, and armour.
They were huge and were in large herds, plus they would have been extremely powerful with their kicks and their extremely powerful jaws since they actually chewed hard food.
@@dieleg Will look at animals like the, American buffalo, cape buffalo, zebra, Biweldabeast, Caribou, Elk, and pretty much any wild bovine speceis. Look Caribou are huge but grizzlys still kill them even when their in herds. Size is a big factor but a head but really isn't gonna do much. But cape buffalo do kill lions pretty often.
@@Tacodile777 Yeah, but grizzly bears just attack a large prey when they are really desperate or when there is no other option, Bears are terrified of adult Mooses because of this
In my opinion I think
Rex>edmontosaurus
Rex>shatungosaurus
And I know they ain't punching bags rex would have a hard time but I do think rex would win
Except Shantungo didnt coexist with Rex. It coexisted with Rex's relstive, however, called Zhuchengtyrannus.
Well now I think
Shat>rex
But I still think rex>Edmonto

Hadrosaurs were defenceless compared to brutes like triceratops and ankylosaurus. It’s like comparing a horse with a rhino and an armadillo.
On one hand, you have a point. Compared to other dinosaurs like large ceratopsians and ankylosaurs, hadrosaurs were not as well defended. On the other hand, just because they were not as well defended as other herbivorous dinosaurs does not mean they were defenseless. Horses, which you compare to hadrosaurs, may not be as well protected as rhinos or horses, but they are still very capable of defending themselves.
@@kade-qt1zu i never said they were defenceless, I just said compared to other heavily armored herbivores they look like puppies
Horses can kill a lion by one kick in the head
@@riyadriyad5911 they cannot if that was the case there would be no lions today because of how incredibly violent and trigger happy zebras are
