It's also crazy that these beasts, weighing up to 100 tons, about half the size of the largest animal ever to live (today's blue whale), had brains and intelligence about the same as a chicken, sometimes literally, and sometimes in proportion to their body mass.
I felt that little tangent at the end there on a personal level, dinosaurs never cease to ignite that childlike wonder and awe that overwhelms me in the best way
It's crazy how the sauropod group containing the biggest animals to ever walk on land (the titanosaurs) also had Magyarosaurus, which was only the size of a cow, and lived at the same time as the other giant titanosaurs like Alamosaurus (right before the big extinction at the end of the Cretaceous). It makes my brain happy thinking of a "mini" sauropod.
It’s also crazy to me how we could’ve had cow size elephants in the modern day if humans hadn’t hunted or exported them to extinction (Mediterranean and Southeast Asian Island elephants).
I sometimes wonder how long it would take for a Argentinosaurus to walk past you.. that sounds weird but just imagine standing there, the earth thundering underneath you as that thing stomps forward. It couldnt have been very fast right
@@realdaggerman105 They may only have been able to move one leg forward at a time though due to their size and weight ...I believe they’ve also found evidence of sometimes multiple dinosaurs and other small animals drowning in mud churned up by sauropod footprints
Alright now onto our first Dinosaur Evolution video centering on Sauropods. Hope you do an evolution on the Theropod dinosaurs, the Ceratopsians, Mosasaurs, Turtles, the Stegosaurus, the Pterosaurs and the Birds.
@@duder7396 I didn’t say that these 3 groups (e.g. Mosasaurs, Pterosaurs, Turtles) are Dinosaurs I just want him to cover them, you didn’t have to sound like a dick.
As a biology student I really love your channel- would love to see more videos on the evolution of extinct animals! There is an near endless supply to choose from. I would suggest gorgonopsids or cephalopods but thats just my bias 😁
I absolutely LOVE the way those impossible names just float off your tongue like music! I've watched Dinosaurs change since my days in grade school, back in the 1950s, sometimes for the better, sometimes not so much, but several things remain unchanged, for me: I wonder what they tasted like and, can you imagine the enormous piles of poop where ever those puppies went!? Must have been Heaven for whatever kind of Scarab beetle lived back then, not to mention the Monkey Puzzle trees.
Your enthusiasm over the massive Patagotitan you saw in the museum was a thing of beauty. It was a really enjoyable video overall, however it was this expression of joy towards something so marvellous that you earned yourself a like and a sub. 🎉 Also!! The memes were good. Mr Crabs doing bench presses are the cherry on the cake. 🎂
i have to say that you’re by far the funniest and most entertaining paleo youtuber. the rest are out here making dumb jokes for toddlers the whole time. you’re just actually funny in a really deadpan way
Over at Dinosaur National Park ( straddles Colorado and Utah ) there is a partially excavated skull of a Camarasaurus. It is almost the size of a Smart Car, which blows your mind knowing that that was the smallest feature on it. Thermopolis, Wyoming has built a two story building to house the juvenile Diplodocus they found there.
Sauropods 🦕 are some of my favorite dinosaurs because of how big they are; their size is really something to behold. Also, that’s so cool with that fossil in the museum. Also, big congrats on this being your first dinosaur video.
My favorite dinosaur is brachiosaurus too. i always find it cool when youtubers I watch share similar favorite things with me. Also the scene in walking with dinosaurs with the dinosaur is really cool
I guess the secret of sauoropods being able to achieve such a huge size and still stand on land is their hollow, air-filled bones. They probably weighed about half what people thought they did when they thought the bones were solid.
Sauropods in media: Biggests punching bags in history, just there to show how powerful carnivorous dinosaurs were. Sauropods in reality: Brontosaurus: Excuse me sir. You’re just in time for the event. Allosaurus: What event? Brontosaurus: *W E I N E R C O M P R E S S I O N D A Y* Allosaurus: What the fu-
Bruh, ephanterias amplexus ate those for breakfast. The ancestor to ths giganotosauridae, rules the jurassic, not the big al variant or what I call allosaurus minus
Hi, I would like to gave you some corrections regarding this video: - Prosauropods is an obsolete term, it has been replaced by "non sauropod sauropodomorphs". - It's Antetonitrus, not Antenotritus, a very cool name, it means before the thunder. - Spinophorosaurus didn't have a spiked club, only Shunosaurus had it, and also Mamenchisaurus even if it was very small. - No, numerous studies showed that Diplodocus and other long tailed sauropod couldn't use their tails for defense, it was too thin to be an effective weapon and the bones would've easily broke. It has been hypothesized that it could've had some communication purpose. - It's not sure Alamosaurus shared its environment with T. rex, they come from different formation, but there are fossils of an undescribed Tyrannosaurid from the same formation of Alamosaurus, which may be T. rex or a close relative. Hope this could help and good luck for your future videos.
My favourite thing about sauropods is just trying to understand that these were living, breathing creatures, it’s difficult to wrap your head around the sheer scale of it, no matter how many reconstructions I see, the scale just doesn’t click, and I love them for that.
Wow, if not your video, I would have not known of Eoraptor reclassification into sauropodomorhps! Reclassification goes almost always under a radar, articles and Twitter posts share almost always info about new species or new study about lifestyle or anatomy, I almost never see something about reclassification. Where did you got an info about Efraasia's cheeks? Btw, wonderful video. Very well done on informative side.
One of my favorite features of the carnegie nature history museum is that you can see diplodocus and apatosaurus from the stacks in the library next door
Small detail: the prosauropods were in fact not the only giants of the Triassic, having to contend with huge dicynodonts like Lisowicia - weighing as much as an elephant, and surprisingly closer to us than to dinosaurs! It is only when dicynodonts went extinct at the end of the Triassic that prosauropods and then sauropods became truly uncontested in size
I agree how cool it would be to witness these giants in real life. But, of course, being wary of those tail whips. A herd of them must have shaken the ground as they walked past. And I wonder what their calls sounded like.
worth noting that sauropods are known to be able to take and run in a bipedal stance when they are hatchlings. They only become 100% quadropedal as they advance through life and begin to weigh to much to safely carry in that running stance.
There were sauropods in the arctic during the late Cretaceous that coexisted with Pachyrhinosaurus, Edmontosaurus, Albertosaurus, Gorgosaurus, Prognathodon, Atrociraptor, Hesperonychus, and Troodon.
No sauropod fossil has ever been found at such hight latitude, and there was also a study who came out last year about how sauropods preferred drier environments due to where their fossils have been found and how their environment was when they were alive
Not all of these animals like albertosaurus that you lived I. Didn't necessarily live in the arctic atleast this isn't one of your phylogenies because your super bad at those
@cholachanth yes, actually, not true, phylogeny gets changed multiple times, especially when morphological or geographical grounds regard traditional placements either paraphyletic or polyphyletic.
@@indyreno2933 well your phylogenies are outdated or just completely made up like or shrews and hedgehogs are in sperate orders ya that's now outdated and they were put back in the same order and I'm not talking about insectivores that is definitely outdated your classifications are known as textbook classifications which are a lot of the times outdated or incorrect so your just insisting on d phylogenies
@@indyreno2933 and yes cetaceans are in the group artiodactyla due to genetic analysis and that's not outdated and there closest relatives hippos so the only reason your separating them is because of morphology now tell me where do you get these phylogenies from your imagination
Sauropods are cool to me cause it makes sense how they got that big and what features allowed them to reach that size but it’s doesn’t make a lot of sense for why such a large size would evolve
7:24 I was the opposite and still am I think that diplodocus (not argentinosaurus) and diplocoidea in general necks look better horizontal Also their teeth are better for low level plants
Nerding time! Sauropods didnt have their nose on the top of their skull! New research has shown dicraeosaurids didnt have spikes, but actually neck sails!
Very cool video and super happy that this featured the Sauropods. Great job on trying some of the most difficult pronunciations. However a few corrections on some general pronunciations - Saurischian (saur-ish-ee-an) and Ornithischian (or-neh-thish-ee-an). I know Sauropods are pronouced sor-oh-pawds, however, when it comes to Sauropoda and other "poda", the paw becomes a po (Sor-o-po-da) like the po in podiatrist. Hope that helps
On the necks, think about it. The throat is an obvious weak point for any prey-animal, evolving a neck held vertically gives the animal a distinct advantage against predators over any animal that holds its throat out in invitation for any T-Rex that happens along. It just wouldn't make evolutionary sense.
I have studied dinosaurs, large vertebrates, and prehistoric mammals. Sauropods seem more "diversified" than they really were, and it seems only three families existed. Prosauropods did not evolve very much and Diplodocus (Seizmosaurus) seems to be the last of these "primitive sauropods." Camerosaurs, Brachiosaurs, and early Titanosaurs could be considered an emergent family of Macronarians or "Camerosaurs" and followed a larger size, shorter length format, and longer arms. Then we see specialized Macronarians with skin bumps, so-called Titanosaurs or Saltosaurs, small to large Sauropods with smaller heads, tough skin, and more evolved neck sacks and skin features (like scales and studs). Many people in paleontology saw Sauropods as many families and wanted or expected perhaps 20-30 families of Dinosaurs, however I see less diversity. It seems true families of Dinosauria are less than 20 and possibly just 8-10. Prosauropods, Camerosaurs, and Saltosaurs. Ceratosaurs, Coelurosaurs, Allosaurs or Carcharodontosaurids, Megalosaurs, Birds as a branch of Coelurosaurids with Tyrannosaurs and Oviraptors in the same family, and then Ornithopods or Iguanodonts, Dryosaurids, and Ankylosaurs (Stegosaurids). I could argue also, Ceratosaurs and Pachycephalosaurs are subfamilies of Dryosaurs, a bumpy skinned branch of Ornithopods with specialized heads and head shielding (fused skull plates, a head fringe). One thing more on Sauropods, they tend to be too diversified with each genus lumped into one or two others as small families or micro-families. Yet, there might be less than 80 species of Sauropod including Prosauropods, individuals or specific finds are often granted a species name for each case. Such fallacies should be dealt with. I also see one other issue, sauropods have only three branches including a primitive or long-form branch. It is likely they also went from 2 or 3 genus at a time to up to 8, during the later Early Cretaceous. One fallen assertion was "they died off largely 145 MYA" but they clearly survived and diversified after the J/C extinction. So, all this considered, you might want to look into it again and update your video. *An environmental biologist.
it's crazy to think these behemoths started out as small, carnivorous, bipedal dinosaurs that looked like Velociraptors.
They started out as omnivorous.
It's also crazy that these beasts, weighing up to 100 tons, about half the size of the largest animal ever to live (today's blue whale), had brains and intelligence about the same as a chicken, sometimes literally, and sometimes in proportion to their body mass.
@@raylopez99 just pointing out that chicken are not exactly as dumb as pop culture drilled into us tho.
They started as Omnivores
But velociraptors had complex feathers and wings, the early sauropomorphs barely had protofeathers
The largest land species to once walk the land. Probably hitting the limits on how far a land species can get so big while still being sustainable.
Also things grew to massive sizes due to the O² levels being much higher than they are today.
Dude. Your thinking of insects
@@kpoper4lyf False, that applies more so to the giant insects of the carboniferous.
@@kpoper4lyf nope
they would probably evolve even further and rule the world even nowadays.
Imagine all the little dinosaurs that probably lived their lives on sauropods that we will never know existed
Like cowbirds? I love the idea!
I felt that little tangent at the end there on a personal level, dinosaurs never cease to ignite that childlike wonder and awe that overwhelms me in the best way
It's crazy how the sauropod group containing the biggest animals to ever walk on land (the titanosaurs) also had Magyarosaurus, which was only the size of a cow, and lived at the same time as the other giant titanosaurs like Alamosaurus (right before the big extinction at the end of the Cretaceous).

Ah the wonders of tiny islands
A tiny giant
It’s also crazy to me how we could’ve had cow size elephants in the modern day if humans hadn’t hunted or exported them to extinction (Mediterranean and Southeast Asian Island elephants).
Hateg island is an underrated oddity of the Cretaceous
Still would absolutely mog the biggest Mammalian predator of today.
Nigersaurus is my favourite dinosaur for no particular reason I just like it.
dark humor mfs when i commit SA hate crime or their babies 😨.
@Empty Glass this is the best reply I've ever seen.
I sometimes wonder how long it would take for a Argentinosaurus to walk past you.. that sounds weird but just imagine standing there, the earth thundering underneath you as that thing stomps forward. It couldnt have been very fast right
Imagine how much longer to stop hearing/feeling it's footsteps 😮💨 a whole herd of them prolly feels like the rumbling from aot
I mean, they’d be relatively fast right? Big ol steps.
@@realdaggerman105 They may only have been able to move one leg forward at a time though due to their size and weight
...I believe they’ve also found evidence of sometimes multiple dinosaurs and other small animals drowning in mud churned up by sauropod footprints
Sauropod crossing 🚸 😂
Nah it would walk with a large idk walking cycle it’s steps alone would make it faster than a human
A separate video on titanosaurs? YES PLEASE 🤩
Dude, your first dinosaur video and easily one of your best videos period. So happy you’re expanding out into other organisms!
Eeyup.
I love how at some point the narrator gets super excited then goes back to talking like normal after a cough like nothing happened.

From dropping dino facts to casually roasting reddit mods. Good stuff.
This is really interesting! As a kid, I never thought about how they appeared. 😅
Man the number of different Dinosaurs sure has grown since I first got interested in them back in the 1960's.
Do it. A whole video on Titanosaurians is what we want.
Where do the beautiful dinosaur names come from ¿
I wonder if they really reached the size limit. The asteroid killed them off, so we'll never know if they could have gotten even bigger.
They didn't die out because of the meteorite, they just evolved into birds because of climate change.
6:38 Surprisingly accurate
Evolution of Ankylosaurs would be a cool video
My boys!!
My favorite dinosaur is either Agentinosarus or Alamosaurus sanjuanensis. Both of them are estimated to have weighed over 50 metric tonnes
I’ve always wondered how evolution would have changed for everything, including us, had the dinosaurs never gone extinct.
My favourite thing about sauropods is just trying to understand that these were living, breathing creatures, it’s difficult to wrap your head around the sheer scale of it, no matter how many reconstructions I see, the scale just doesn’t click, and I love them for that.
Even as a Ceratopsian guy, I have to admit Sauropods where awesome.
I’m using this video to study for a dinosaur exam, thanks for the vid dude. You should cover the history of the ornithopod dinosaurs.
12:05 woah I thought you were a laidback book worm nerd 😂 the BRO in you really came out 😳🫣🤣
Now even though all these sauropods are fascinating,
Redditorpods >>>>>>
That's probably why Fred Flintstone and crew used them in their construction job's... 🤔

Could you do an evolution of lemurs/prosimians vid? I know there's one for monkeys but prosimians would be great to see too
Brachiosaurus is my favourite too. Thanks for sharing!
Lol i love that hype when u were talking about ur museum trip
With that severe overbite, Sauropods didn't smile much.
Science should serve to make things as cool as possible: total agreement from me.
worth noting that sauropods are known to be able to take and run in a bipedal stance when they are hatchlings. They only become 100% quadropedal as they advance through life and begin to weigh to much to safely carry in that running stance.
Just found this channel and I LOVE it
10:10 Seriously, am I the only one who knows about the country of Niger?
“The last time I studied dinosaurs was in 5th grade”
And they called me crazy for thinking dinosaurs didn’t roar like lions and tigers
You should do a video on the Bruhathkayosaurus--possibly the largest sauropod ever discovered at up to 190 tons.
What was similar but had 2 heads and 2 tails was the: Sweetopods. They were really cute when young.
Those aren’t even dinosaurs.
1:18 как же я испугалась🙈

Yo you should do Tyrannosaurs next. They have just a complex evolution just like Sauropods.
I’ve never known a little kid that didn’t love dinosaurs. They may be out there, but not common.

It makes a lot of sense, it was an evolutionary race with the theropods, the bigger you are the lesser you are vulnerable to predators

Birds as a branch of Coelurosaurids with Tyrannosaurs and Oviraptors in the same family,
