Brachiosaurus: One Of The LARGEST Animals to Ever Exist | Dinosaur Documentary

[@kenyongray2615]

What a monster. That is meant as a compliment. Thank you for featuring one of my favorite dinosaurs.

[@vladline1882]

Finally.. my favorite Sauropod got some love

[@nicosy282]

me too

[@Ladybhive71]

Yes he did🦕❤

[@pienpien2]

It’s the only dinosaur with a smile ❤

[@walterfechter8080]

When I was a kid, I called Brachiosaurus, "A dino-swan." Many thanks, Dinosaur Discovery. This video is superb.

Small story: Why did the Brachiosaurus start a career in espionage? Because it thought it would be the perfect undercover agent, given its ability to blend in with skyscrapers. On its first mission, it was tasked with a simple surveillance job. However, it stuck out like a sore thumb, or more accurately, like a giant dinosaur in the middle of the city! It tried to disguise itself as a modern art installation, standing perfectly still with a pigeon on its head and tourists taking selfies. The mission was a bust, but it did accidentally uncover a spy ring: a group of squirrels using acorn messages. The Brachiosaurus returned to the agency as a hero, not for its subtlety, but for being the most noticeable "incognito" agent in history. Its career in espionage was short-lived, but it always remembered the thrill of being mistaken for a peculiar piece of art.

Great vid. I always look forward to these videos :)

[@Roberto_Valencia]

Alongside Giraffatitan and Sauroposeidon, Brachiosaurus is my favorite dinosaur species.

[@A_Kulcsar]

Had to do a double take at 17:58. Didn't know sauropod mahout was a career option.

[@Georezzi]

Love this

[@TransVangal]

Love this channel

[@xmtryanx]

A mostly intact brachiosaur was destroyed in the Berlin museum during the war

[@jeremyfong5684]

So was the first and only Spinosaurus skeleton

[@olafwolgast3127]

Still they have a skeleton, put together from 5 individuals. Very impressive. Have been visiting it for years.

[@JH_789]

I would like to see information on the environmental carrying capacity of animals like this. How much land did it take to support them? How might trees have coped with such heavy pruning?

[@cameronpahl]

This is one of the biggest unanswered questions in paleontology. Especially because the Morrison Formation was a pretty harsh environment. The climate had wet and dry seasons, so the whole landscape flipped between desert and monsoonal rains /floods every year, so it is strange that so many gigantic sauropods were able to survive there together. But we know the population of each species had to be high enough for them to be reproductively stable for tens of thousands of years, and fossil evidence tells us they were very common. So there is some missing data for sure. Jim Farlow wrote a great paper on this in 2010 called Giants on the Landscape - he estimated that there was a population density between 1 and 15 sauropods per sq km if they were endotherms. 2 years later other researchers estimated there were about 10 sauropods per sq km at any given time, which makes sense logically but also seems insane. Think about seeing 20 or 30 of them migrating together - we know they did this, but how the environment supported them is not really understood yet. There are even papers about whether or not the Morrison had "too many" sauropods, because it is an open question. You can read more about it here: www.tandfonline.com/doi/full/10.1080/08912961003787598 phys.org/news/2012-05-gaseous-emissions-dinosaurs-prehistoric-earth.html And finally this paper: journals.plos.org/plosone/article?id=10.1371/journal.pone.0290459

@@cameronpahl Thanks for the information!

[@davidboyle1902]

Depictions of sauropods standing in neck deep water are ridiculous. These animals are so large that the pressure on their chests would be on the order of 1 atmosphere, making breathing impossible (which is why people cannot functionally use snorkels more than a foot in length). This has been known for decades, and to show such depictions significantly detracts from the believability of the information being presented.

Oh…lighten up David…😊

"It's a Brachiosaurus" 🦕

[@kolaiktomi]

Growing up in the 80s, it was taught and believed that these beauties lived in swamps and lakes. Lurking around submerged with only the tips of their "noses" breaking the surface like a crocodilian. Even as a 5 year old, I saw no reason for an herbivore of such immense proportions to develop such an adaptation unless it was omnivorous. Several years ago, studying hadrosaurs, it clicked in my mind that the crest was used for communication. Long neck, tiny head and no real evidence of vocal elongation, it would have sounded like a weird fart and seems its dome was used to control pitch. There's not much bone there for substantial resonation but it would seem they could control pitch somewhat.

[@EquineMetalhead]

My favorite sauropod ❤🤘🏻

[@neilfoss8406]

Elephants are great swimmers, why couldn't these. I find this all believable. I don't think we are likely to ever know for sure the ways these animals actually lived

[@jamesvanstone-i4m]

Famous Legend Dinosaur Brachiosaurus😊🦕💙💜

[@kevin-n-darlenef301]

That was a battle, kookaburra!!

[@neilfoss8406]

I breathed under 7 almost 8 feet of water in our swimming pool. This animal, I think, would benefit from the displaced gravity. A Mouse feeds completely under water, I have seen footage of it actually doing just that, on lake bottom vegetation in Canada and Alaska.

"That's a dinosaur"

[@jojofarley4511]

Why was there a human leaning over the fallen dinosaur near the end???

[@Helenium1001]

Dino Saucer

[@ddwalker3744]

I have to go look it up I have no idea how long 26 meters is

[@allensaunders449]

Very difficult for an animal that large to hold it's head up high. Puts alot of pressure on it's heart to pump blood to the brain

[@szodoss7764]

Brachiosaurus was the second or thrid largest in "jurassic" period in "north america"...

[@SanG-tc3gb]

I find all sauropods same... pillar like legs.. big cylindrical body.. long neck and tapering thick tail....

[@CT9905.]

You mean Brontosaurs, correct?!

[@Necronomicon-thebookofthedead]

at "how was brachiosaurus discovered" do you think it might have been like a liger or prizzly bear? the liger comes to mind as a cat basically the size of a bear and both of it's parents together, as if had a chromosonal condition of magnificient sort

[@Necronomicon-thebookofthedead]

or troglodytic vermin, like a water horse, the loch ness monster trapped in a lake (it's actually a ghost but w/e that's ufo shit)

[@TomTurbo-wh6op]

Wrong, referring to the neck posture.... following the Brachiosaurus' backline, his neck was more likeliy held in an angle of around- 40-60° to the horizontal. Just google Brachiosaurus, there is a more recent drawing of the animal.

[@erichilgart]

I still think they hung out in the water.

[@A_Kulcsar]

As long as they kept their lungs near surface level that still works but the buzzkill for the old idea of underwater 'snorkeling' sauropods (like the classic Charles Knight painting at 18:35) is water pressure. Each foot of fresh water weighs .432 pounds, so if the animals head was at surface 30 feet above its lungs that's almost double atmospheric pressure squeezing the air upward. Even an animal as big as a Brachiosaur couldn't inflate its lungs against that kind of water pressure.

[@erichilgart]

Them skinny legs look like they would suck to walk on all day.@@A_Kulcsar

[@DrKerstin]

Q😅o😅

[@chrislee4322]

Dinosaurs are not reptiles

[@archer-z1f]

what are dinosaurs then ?

[@PlainsPup]

Yes, dinosaurs - including birds - are technically reptiles (diapsids).

[@plaguecrawler4645]

Birds are technically Reptiles, so yes Dinosaurs are Reptiles

[@Nate-1244]

The group Dinosauria is ultimately placed within the class Reptillia. So, yes, dinosaurs are reptiles.
