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.

[@thehiddencryptid]

Ah the wonders of tiny islands

[@invisiblejaguar1]

A tiny giant

[@genghiskhan6809]

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).

[@farhanatashiga3721]

Hateg island is an underrated oddity of the Cretaceous

[@ekszentrik]

Still would absolutely mog the biggest Mammalian predator of today.

[@veggieboyultimate]

it's crazy to think these behemoths started out as small, carnivorous, bipedal dinosaurs that looked like Velociraptors.

[@user-pakshibhithi10]

They started out as omnivorous.

[@raylopez99]

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.

[@fabrizioart1928]

​@@raylopez99 just pointing out that chicken are not exactly as dumb as pop culture drilled into us tho.

[@mhdfrb9971]

They started as Omnivores

[@franciscozapata7625]

But velociraptors had complex feathers and wings, the early sauropomorphs barely had protofeathers

[@raynelaroux1547]

Love how you got so excited about the fossil at the Natural History Museum and then with a throat clearing your back to the video. It's great to see some personality in your video than just all facts

[@weasele1]

was this at the musium in NEW YORK ? to bad im in floruduh

[@johnchao2422]

Yeah which natural history museum is it??

[@GosarX]

i liked your comment before i got to that part just because i agreed that its nice to see our youtubers personalities shine in here and there! but i def felt his energy! i had the same when i first went to the denver museum when i was younger than 10. and seeing those replication skeletons in person really makes you feel something. i grew up in phoenix and people always said, "i seen pics of the grand canyon, im good" nah you need to go there at least once in person to truly appreciate it, one of those "pics dont do it justice" things

[@fireraid2336]

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.

[@kpoper4lyf]

Also things grew to massive sizes due to the O² levels being much higher than they are today.

[@gojizard704]

Dude. Your thinking of insects

Like cowbirds? I love the idea!

[@reign9093]

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

[@mickhack8034]

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

[@ongong5496]

Imagine how much longer to stop hearing/feeling it's footsteps 😮‍💨 a whole herd of them prolly feels like the rumbling from aot

[@realdaggerman105]

I mean, they’d be relatively fast right? Big ol steps.

[@TellEmB290]

@@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 🚸 😂

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.

[@jaycejones4928]

You should absolutely do more videos about Mesozoic life. This was a treat

[@v0rtvixen]

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 😁

[@Gigazilla-pm2on]

All right here we go our first dinosaur evolution video

[@Sarafimm2]

They just recently found out through scanning the neck bone fossils that they may be hollow like bird bones and stacked in such a way like puzzle pieces to balance those super long necks.

[@walterfechter8080]

When I was a kid, I told my first grade teacher that I had an invisible brontosaurus in my family's barn. I also mentioned that the hay within our barn kept disappearing. I owed that to the bronto munching on the hay bales. I never mentioned to my teacher that local farmers would use our barn to store hay for them to take away anytime they needed it. One of my all-time favorite fictional dinos was the brachiosaur-like radioactive monster in "The Giant Behemoth" (1959). I've loved brachiosaurs ever since. Thanks, Animal Origins, for this very informative video on my favorite dinosaurs.

[@dinomation]

Glad to see your talking about my favorite dinosaurs and explaining their history!

[@vice.nor.virtue]

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. 🎂

[@Charlie._.Niron22]

A video about my favourite group of Dinosaurs?!? Sweetness 😊

[@ilyaslebleu1947]

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

[@RishiRose_]

I love how at some point the narrator gets super excited then goes back to talking like normal after a cough like nothing happened.

[@fredwood1490]

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.

[@wolfie1703]

I think scientists tried to figure out what a t rex tasted like a bit ago. Look up "what would a t rex taste like"

[@Gamerafighter76]

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.

[@johnhanover2229]

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.

[@mckinleyt98]

how you felt about that giant fossil is so relatable i think i would cry if i saw it in person

Man the number of different Dinosaurs sure has grown since I first got interested in them back in the 1960's.

That description on the titanosaur skeleton... you had me imagining it (which I'm sure doesn't do it justice) and I just... I can't... I understand the science of why sauropods got so huge, but I still can't and never will be able to get my head around them.

[@v0rtvixen]

Wow this is crazy! Never thought that sauropod ancestors would look like theropods! Really fascinating

[@mhdfrb9971]

Sauropods are closer to theropods than to the Ornithischians

[@TheGBZard]

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

Love 10:27 How I imagine these majestic creatures really looked like on the horizon. Sad they have been extinct for over 60m years. Still, they are able to be appreciated by you and me thanks to science and the curiosity of our species. Sad, yet a beautiful thought. Cheers

[@OmegaWolf747]

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.

[@obibraxton2232]

Yay more dinosaur videos please can you do the Chasmosaurus and related next ?

Brachiosaurus is my favourite too. Thanks for sharing!

Best sauropod video ever!❤

[@davidlange1000]

Fascinating video my dude

[@Fede_99]

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.

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.

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

[@evelynlamoy8483]

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.
