Barosaurus: The Longest Known Sauropod Dinosaur
Вставка
- Опубліковано 8 лип 2024
- Barosaurus was a massive sauropod dinosaur and possibly the longest one known to science. While thought to be about as large as its close relative Diplodocus, it was previously only known from immature specimens, and a massive Barosaurus cervical vertebra suggests a length of 45 meters and a weight of about 60 tons. Barosaurus lived in the North American Morrison Formation during the Late Jurassic period, the same time and place as about half of the stock dinosaurs most people are familiar with.

Interesting video, pretty well put forth and in a digestible format, though I do feel it falls short within the realm of research a slight bit, and comes at a... tumultuous time in Barosaurus' history.
a 2021 SVP abstract tries to argue for the BYU 9024 sepcimen to stay assigned to Supersaurus, though I will say I do not fully agree nor understand the reasoning behind the abstract's conclusion myself. Nevertheless it is something to keep in mind.
Barosaurus' giant estimates can actually be referred from multiple specimens, most notably the cervical series assigned to the number of BYU 20815 that contains three full cervicals, and the YMP 429 leg fragments which were found intermingled with the holotype specimen of Barosaursu itself. Furthermore Barosaurus might very well be two distinct species as there are notable differences found in things such as the ROM Barosaurus specimens and the Holotype.
I'd say this is really good and a fantastic start for an upcoming person in the paleo-community, keep at it dude!
Amazing how a sauropod fossil can be just 'forgotten' about.
Not just "A" fossil mind you. The largest terrestrial animal
rebbachisauridae: forgotten
diplodocidae: forgotten
sauropods: forgotten
titanosaurs: being forgotten but not yet
Thats the nature of fossil media, I'm afraid; if it doesn't get a pop culture appearance that captures the published imagination, it fades out. Look what happened to Ceratosaurus and Allosaurus after T-rex hit the big screen. They were THE stars of dinosaur movies in the days of Ray Harryhausen.
People..are people..
Hopefully one day Barosaurus will get it’s opportunity to, shine in the limelight of the general public.
Why? Do you think long extinct creatures give a damn about our recognition? Do you think they are as lame as you & need likes on their social media? Do you honestly believe the barosaur species will look down at us from dino-heaven & smile upon humanity for finally giving them some limelight? Sheesh. Grow up, kid.
@@marblemadness8870 No it would just be cool to see it in other media like Jurassic world Evolution.
@@marblemadness8870 I’d just love to see it in media, such as art, games, movies, etc. There’s a lot of interesting dinosaurs that don’t get enough recognition.
@@marblemadness8870 hes Litteraly saying that it would be cool for barosaurus to be known atleast as much as diplodocus chill man
@@marblemadness8870 yo you had a bad day or what?
How did this absolute unit of an animal even came to be ? It blows my mind. 45m, that's as long as the mosasaur from the Jurassic world movies
Built different
I’d want one as a pet.🦕
It is amazing, though.
@@yvellebradley2502 No, you wouldn't want one as a pet. You would become homeless in a day trying to pay for its food.
Then wouldn't it be longer that a blue whale
@@mab_25 It would
It makes me sad how little most people care about dinosaurs 😔 I've been obsessed my entire life and I loveee talking to people about them
I remember as kids a lot of us were, maybe because of the Jurassic Park movies. As we grew up most people kinda just forgot. My interest came back thanks to all these educational UA-cam videos I now watch. Most adults just care about other stuff I guess…
Me and my friend used to read all the dinosaur books in the library at elementary school together. Every day we'd pick out which dinosaurs we wanted to be at recess. I was also well known for always bringing in my Jurassic Park toys for show & tell. Somewhere along the line I lost my inner dinosaur but obviously I still like them because I'm here.
A lot of people think they weren't real, they are so different to modern animals that seem almost fantastic, but that's the reason why most of us like them ,right?
Same! My interest started as a 4 year old and i was obsessed with dinosaurs as a child. At my 10th birthday i got my biggest birthday wish fullfilled - I got taken on a private tour at the natural historic museum with a professor in paleontology! When JP came a year later or so, it was the biggest happening ever!
I still got my interest and it has been transferred to my children. Dinosaurs are awesome!
Me too. Literally none of my friends like them. I made my friend watch Jurassic Park 3 once, and that's the only time I've watched/discussed dinosaurs with anyone
I remember reading about barosaurus in my dino books as a kid, but back then it was thought to be a smaller diplodocid. I think its demure rep is a result of updated data on the species not being adequately communicated to the general public throughout the yrs.
Imagine what it would be like to see a fully grown sauropod of this magnitude. Been a dinosaur lover for all my life and never knew of Barosaurus. #Subscribed 💯🔥
Presentation by Brian Curtice at this year's SVP annual meeting argues that all the diplodocid material from the Dry Mesa Quarry (including the BYU 9024 Barosaurus vertebra and Dystylosaurus) belong to Supersaurus vivianae after all based on newly prepared material. Turns out proximal cervical and caudal Supersaurus vertebrae are indistinguishable from Barosaurus, despite the rest of the skeleton indicating that Super is apatosaurine rather than diplodocine.
My knowledge of barosaurus was literally that it was a diplodicid and it was big. Cheers for the video on a fricking huge and underrated dino. I can imagine barosaurus using those diplodicid peg like teeth to strip Kauri (agathis)leaves (and other broad leafed conifers)from up high when rearing on the edge of riverine forests. I imagine they would work well harvesting podicarp fruit and leaves as well, on top of the usual fare of ferns, tree ferns, horsetails and maybe cycad fiddle heads and fruit, i mean cycads are pretty spikey and defensive, but a big neck like that should be able to reach out over the spikes for a top down attack, even deep into the heart of a large cycad grove.
TOTAL DELUSIONAL CRAP!! THEIR TEETH ARE MADE FOR GRABBING/HOLDING AND TEARING FLESH, LIKE THE FISH THAT ARE THEIR NATURAL PREY!! There are NO GRINDING TEETH FOR VEGETATION TO BE PROCESSED!! THEY ARE CREATURES OF THE HORIZONTAL PLANE, NOT THE VERTICAL!!
THEIR MASSIVE, LONG, THICK NECKS ARE NOT GOOD FOR RUNNING/JUMPING/HOPPING AROUND IN THE VERTICAL!! THEY HAVE NO LONG CLAWS WITH WHICH TO GRAB ONTO SPIKY TREE TRUNKS!! THEIR FORELIMBS ARE BIG LOBULAR OARS TO PADDLE ABOUT WITH!! THEIR REAR LIMBS ARE
SMALLER THAN THE FRONT ONES SO THEY ARE TOO WEAK TO SUPPORT THE MASSIVE UPPER BODY WHICH MAKES THE HYPOTHESIS THAT THEY COULD STAND ON THEM ALL DAY LONG ABSOLUTELY RIDICULOUS!! THE PERCENTAGE OF THE UPPER BODY WEIGHT WOULD BE ALSO FAR GREATER TO SUPPORT ON SMALLER LEGS IN THE BACK!! BUT THOSE SAME REAR LIMBS WOULD HAVE SERVED VERY WELL AS STEERING and TRIM ADJUSTERS ON A SWIMMING ANIMAL IN THE HORIZONTAL PLANE!! I'M SORRY BUT THE "DISCOVERER" OF THE BRONTOSAURUS WAS MISTAKEN TO PRESUME THAT IT WAS COLD-BLOODED AND LIZARD-LIKE!! THIS MISTAKE SPAWNED THE NAME AND WHOLE GENRE OF "DINOSAURS"!! IT WOULD HAVE BEEN FAR BETTER TO PRESUME WARM BLOODED ORIGINS!! THAT WOULD BEEN FAR AND AWAY MORE ACCURATE!! THESE ARE THE "FIRE-BREATHING DRAGONS" OF
OLD AS THEIR ANCIENT OBSERVERS WOULD HAVE SEEN!! THE STEAM ON THEIR BREATHS COMING OUT OF MOUTHS AND NOSES WOULD HAVE SEEN TO BE SMOKE AND "WHERE THERE'S SMOKE, THERE'S FIRE!!", AS THE OLD ADAGE GOES!! IT LOOKED LIKE SMOKE, SO THEY THOUGHT IT WAS!! GET REAL, MAN!! ALSO, IT IS WAY MORE EFFICIENT TO EAT FLESH(MEAT and ESPECIALLY FISH) FOR ENERGY NEEDS WITH A LONG NECK!! THESE ARE THE "NESSIES" OF LOCH AND THE "CHAMPS" OF LAKE CHAMPLAIN!! THEY DON'T SPORT ACTUAL
FINS LIKE TRUE PLESIOSAURS BUT RATHER HAVE BIG LOBULAR OAR-SHAPED FRONT AND SMALLER REAR LIMBS THAT FACILITATE THE OCCASIONAL TRAVERSE OVER LAND!! EASIER TO SLIDE OVER WETLANDS AND PUSH YOUR WAY THROUGH THE WATER, AS WELL!! BUOYANCY AND
STREAMLINED BODY SHAPES ARE MUCH MORE EFFICIENT AT ASSISTING MOBILITY THROUGH WETLANDS AND BODIES OF WATER, AS WELL!!
Barosaurus: Some people call me Baro, but you can call me Barry.
Also Baro: Welcome to the Long Neck Club. Btw, do you know where I can find a chiropractor?
With a little bit of tweaking, I think you'd be able to adapt a saddle to fit just behind the head, and ride it into battle.
Yes and roll down a mountain with that chuncky dino
@@kaijuking2276 yeah….that would suck
Sounds like ark
Use it as a live siege tower
Once you reached the battle, it wouldn't be a battle any more
holy moly the skeleton of it rearing up defending its young really shows the length
Fadeno's restoration for the largest barosaurus holotype(estimated from a femur and tibia so size varies) is somewhere around 52 meters,other people say its 50 meters
With other specimens being more compact,they can reach 48 meters
After seeing the picture at 1:35, I need to research the Bone Wars now.
There’s videos are really good and appreciate you putting the extra effort into time stamping it all too
So cool. I always remember Barosaurus from one those DK dinosaur books I grew up with the 90’s. You’re right, it’s a somewhat forgotten dinosaur, but I’m glad it’s getting more recognition! I had no idea they could be that big, that is amazing. What a magnificent animal.
Barosaurus really "passed the bar" for tremendous size.
i see what you've done there...i expect you've already seen your way out
My favorite sauropod and one of my favorite dinosaurs of all time.
This channel was recommended to me suddenly and is one of the few good things to happen to me this year! Keep posting more interesting stuff!
This year or last year?
Amazing work. Immediately suscribed. : )
Thank you for creating this interesting video. I truly enjoyed it.
Excellent video incredibly good documentary as always!
I can imagine a scene in a movie where we see the usual Brachiosaurus drinking water and then a new Dino comes into the scene and looking 3 times bigger than the full size brachiosaurus.
Barosaurus no matter how long is not bigger than brachiosaur. You cant compare an adult with a juvenile. Remember breviparopus? Estimated to be around 40m long. Will be twice as heavy as a 50m long baro
Wonderful information. I soak up as much as I can with reference to dinosaurs. I give this video an Iquanodon thumbs 👍 up.
146 feet? That’s as long as a Boeing 707. It’s truly amazing, and beats my old record of 131 feet for some now second-rate dino. Great video.
Fantastic video, I agree with Levi's comment; a great deal of important relevant information delivered in a beautifully succinct way!
seriously how fucking big where these animals??? Imagine the vast amount of available biomass for them to eat on a daily basis alongside other less as big (which changes fucking big to big ass big) sauropod species.
I always wondered how these titanic creatures could eat enough to grow to such massive weights and heights. Now I suspect they lived more like giant tortoises. Where they stood in the middle of medium size trees and grazed moving their necks among the corpse of trees until they stripped them, conserving energy. Only then they may slowly move on to another grove. I have to ask is it possible for sauropods have build up plant toxicity in their blood to help drive predators away?
Size would be enough as a defence.
With something as large as a sauropod, predator would use a strategy called persistence hunting. The predator/s would wound its prey - lets say on the calf to produce blood loss and keep dodging the creature attacking in and out over hours, or few days time, until it collapses from blood loss. And size may not matter if predator/s were quick and agile. In the Dinosaurian world, I see all these massive predators and I don't think they moved as quickly as everyone once thought to get in and out with out some damage. But the mid size range predator/s, and that includes younger T. Rexs might be able to use this strategy.
@@highfive7689 That only works up to a certain point, above a certain size this technique takes too long to be worth the effort. Furthermore, this hunting method favours a predator adapted for precise slicing wounds-so tyrannosaurs really wouldn’t have been able to do it nearly as well, as they were specialized for gripping and crushing instead (it would be the carnosaurs, with their weaker jaws but much better slicing capabilities, that would be suited for attacking in such a manner)
@@highfive7689 the sauropod were the most dumb dinosaurs, thats mean they would have been in groups and not alone, only on early years sauropods were all alone trying to grow as fast as possible.
@@highfive7689 That would only work with solitary prey. Komodo dragons do this, and they only attack solitary prey
Animals in Africa like lions don't do this because the prey animals live in families and groups, so it's too dangerous, not worth the risk of sneaking an attack and getting stomped to death by an angry buffalo or giraffe. When hyenas hunt they use their numbers to try to overpower the prey if they live in small families and catch a weak member, like a calf or an old or sick specimen that can't keep up with the group. When they hunt solitary animals like hippos, they do that, wound the prey from behind when they can't use their defenses like their mouth, and start eating the prey alive
I'm pretty sure these dinosaurs lived in families too
Supersaurus: hold my gastroliths
Imagine being near that thing while it was walking by, 😯
The size of that animal is quite incomprehensible to me!
Barosaurus is a very forgetten dinosaur even by myself. I discovered this in a Dorling Kindersely book and it's very much like Diplodocus. Now that i am much impressed with titanosaurs like Dreadnoughtus, i feel that i betrayed the Barosaurus for forgetting it
Love the talk ❤
imagine how long it would take to swallow food with a neck that long lol
Was just at the Royal Ontario Museum earlier this month, the Barosaurus was very impressive to see but I didn't know it wasn't even an adult yet!
Barosaurus has been a childhood darling of mine along with citipati because of ye old roblox dinosaur games.
Dinosaur simulator gang rise up
Im surprised Mamenchisaurus isn't mentioned among the hall of fame of longest or largest sauropods
That’s true. It may have been as large as Argentionsaurus and Maraapunisaurus !
Thank you . It made me feel like I had a child's imagination again.
That single cervical bone sample is just absurd. I audibly gasped when you showed the extrapolated size!
good show
"Larger than any other dinosaur in the Morrison Formation"
Marapunisaurus: *Finally A Worthy Opponent, Our Battle Will Be Legendary!*
On a Side note this is a great well made video, Keep up the good work
Even If Maraapunisaurus was shorter than Barosaurus, it was likely heavier, thought as we know little about these dinosaurs, we must not make absolutes.
@@SpaceLover-he9fj Obviously. Whilst I love the bizzare nature of Maraapunisarus I don't mean to try and make absolutes as you are correct that both of theese are so fragmentary that we know little about them.
True.
Could you imagine riding one of those??
Can’t even imagine what these things looked like while moving and breathing. It’s mind boggling that these creatures ruled the earth
4:15 so we found little foot's hero
My favorite dinosaurs have always been long necks
Idk why it just hit me that trees must have been crazy tall for them to need to be so long
Not necessarily. Your average pine tree today is probably what most trees would've been like in terms of height. In fact, the largest trees we know of still exist, the sequoias and coast redwoods which can get to heights of 115 meters. Prehistoric trees like Araucaria mirabilis got to similar heights. they used their long necks to reach tall trees, but that doesn't mean trees would've been like huge compared to what they are today.
Okay so this thing is possibly an actual kaiju
never heard of this beast
so 45 meters or about 148 feet in human measurements
Is Dreadnoughtus bigger or this now surpassed him?
Fun fact,: Barosaurus is found, especially in the Morrison formation of South Dakota and Utah
The king of the Morrison.
Maraapunisaurus: Am I a joke to you ?
I always wonder how walking works, with your head thirty feet in front of your body.
this thing is the destroyer of elders
The young man behind this chanell is extremely intelligent and talented paleontologist. What I don't understand is how he finds time to make this videos, while juggling at least 8 maybe 10 college girls who are clawing to date him . Paleontology is 2020's chic magnetism.
Dinosaur simulator be like : one of the most reliable dinosaurs too
Wow Barorasaurus?
I guess Argentinosaurus/Titanosaurus just got moved to the back of the line this is awesome. The Sauropods were always my favorites beginning with Brontosaurus but, that's because I was attracted too strong sounding names that carried an edge of strength.
Brontosaurus means Thunder Lizard that's why I love that name instead of Apatosaurus that name sounds weak lack of strength no pride.
Barosaurus was the longest Argentinosaurus was the biggest
@@E.94772 Thank you for telling me; this is so exciting, to learn.
We know little about these animals, so don’t make any absolutes. Argentinosaurus may have been shorter, lighter or bulkier, why Barosaurus might have been thinner, longer or more robust.
In the 90ties, in my books the Barosaurus was known as the most heavy dinosaurs, hench its name.
Wonder full.
i wish i see dainosour in really.
What about seismosaurus?
i knew about byu9024 from a video which claimed it as a barosaurus. i did further research and thought it was a supersaurus. now this is an update, it is again a barosaurus
What about amphicoelias?
If the T rex was the king of the dinosaurs, Barosaurus might as well be the God emperor of dino-kind.
Just waiting for the Ark update that brings this bad boy in. Im gonna harvest all of the berries
This is the dinosaur that Fred flintstone used as a ride 😂
Barosaurus: 27 - 45 meters ( 90 - 148 ft )
Argentinosaurs: 30 - 35 meters ( 98 - 115 ft )
Patagotitan: 31 - 37 meters ( 102 - 121 ft )
Well the biggest barosaurus specimen was 53 meters (165 feet)
@@RasmusGuineaPig it was 45 metres
@@ayankhanayankhan2012 1 feet = 30 cenitimeters/0.3 meters, and the longest was 165 feet, so 3 feet is 90 centimeters/0.9 meters, so if we wanna make it easy for us, let’s do like this: 165 x 3 = 495, so 49.5 meters, right? Wrong, because this way it’s like 3 feet is 1 meters and not 0.9, so to get the correct answer I am too lazy to do the math in my head, so I am gonna use the feet to meters calculator, I seem to have remembered wrong, it’s not 53 meters, but actually 50.2900 meters :P
@@RasmusGuineaPig bruh tf are you tryna say ?
@@ayankhanayankhan2012 tbh I have no idea lol
Is it still true ( as I once read) that an intact skull for this creature has not yet been found and that the head shape is essentially conjecture on the part of fossil experts?
Watch the video again to find it out
This is way larger than what I remember reading about it.
It probably spent all day eating, stopping to sleep or mate. Must have been a sight to see though, not that any human ever has.
As much as I would love a 45m sauropod to exist, I find it highly unlikely. This is probably a Seismosaurus issue all over again.
Something that big would've needed big meals of vegetation daily to survive. I wonder if the different oxygen composition at the time was also a factor.
But with regards to your comprehensive saur-list.. I think you kinda, accidentally, may have snubbed the #1 Pod!!... The number 1 Saur in your heart, soul, & saur... The absolute coolest, nicest, happiest, most loving & caring Sauropods, of all-time!!.. The one, the only one, THE NIGERSAURUS!!!
The Nigersaurus... A radical, favorite Saur, loved by all... The always-friendly, awkwardly clowning Nigersaurus, would share his personal watering-hoe with any thirsty creature! That's for sure!! That Sauropod is definitely all of OUR, all-time favorite's!!
When I was a kid, this species was simply called Brontosaurus.
Brontosaurus is a different sauropod.
And I thought seismosaurus (diplodocus hallorum) was long
he s one of the smallest if I'm pretty sure..
@@oxidius. Seimosaurus/D. hallorum is still huge, over 100ft/30m long based on current estimates.
I might be one of the few people who'd known of this dinosaur from a Doersy-Kinderling book that described it, once I saw the name I was immediately interested in leaning more
Saw that first cast.
For know supersaurus is still the longest dinosaur but still amazing video
If this guy is 45 meters, that makes them the longest vertebrate ever
Museum stored collections can be so confusing.
I tend to notice most people forget that Seismasaurus still exist
Not anymore
In 2006, Seismosaurus was sunk into Diplodocus (as Diplodocus hallorum) and shrunk down to a length of 29-33.5 m, with a probable weight of well below 30 tons.
1:00 why did you list brontosaurus and apatosaurus consecutively when they're the same dinosaur?
Brontosaurus was found to be its own distinct genus back in 2015.
@@chimerasuchus oh SHOOT thank you I didnt know
Isn't the longest Sauropod Seimosaurus being at the length of 130 to 170 feet or 39 to 52 metres
Its now renamed Diplodocus
"Barosaurus." 😅🤣😂
That's what we used to call the girls that sat at the bar all night, looking for dudes wearing beer goggles, to buy them a drink.
A 60 tonne estimate makes it just a bit smaller than brachiosaurus, being 62 tonnes.
fun fact: barosaurus has at least 7 hearts (seriously)
I got my barosaurus toy from grandpa and grandma
barosaurus was the chunkiest of the chunky sauropods
Now barosaurus byu924 is the third largest dinosaur of all time because of a 2023 study
Jesus H Christ these things were huge beyond perception
I reckon i could still tame it in ark with a club and a couple bolas
I find these gigantic long neck dinosaurs much more interesting then tyrannosauroids. Just imagining standing beside such a creature fills me with awe.
What about mamenchiosaurus?
I thought diplodocus is the longest Sauropod
Supersaurus is now the longest
Its only 33 m
@@ayankhanayankhan2012 It's 39-42 m with the new estimates of 2021.
Possible, but any length or size estimate must be taken with caution, as we known only a little about these animals.
I want see a barosaurus next to an Argentinasaurus
Amphicoelias’s will lives on in Barosaurus
Given their long necks. I doubt they could hold their neck up for any long periods of time. Probably only to feed and/or two scape potential predators.
Barosaurus, along with Argentinosaurus, Maraapunisaurus, Mamechisaurus and other unnamed large dinosaur specimens are candidates for the largest dinosaurs known, although, as usual, These length and weight estimates must be taken with caution, as we know little abou these creatures.
If ever Maraapunisaurus is actually confirmed a real animal with more complete bones got discovered, it will put titanosaurs to shame and make Jurassic Period the real Time of the Titans (Pun intended)
Isnt amphicoelias fragillimus and bruhatkayosaurus technacly bigger? Even tho they probably didnt exist as the paleontologists were assumed to be lying even tho never actualy disproven?
Amphicoelias fragillimus is now Maraapunisaurus (a rebbachisaurid rather than a diplodocid) and estimates of it's length have shrunk to a little over 30m/100 ft. Bruhathkaysaurus material was destroyed before anyone could get a detailed look at it so we'll never know if it was a genuine dinosaur or petrified tree trunks.
@@Ozraptor4 yes i know about that
More recent studies, however, suggest that Maraapunisaurus couldn’t be less than 35 meters. In fact, it may be as long as 45 meters !
Not to be a sceptic, but how the hell could O.C. Marsh publish in 1999? Wasn't he dead?
Argentinosaurus: Am I A Joke To You?
barosaurus sure looks like a basal diplotocid; it probably didn't have the ability to stop growing until it got too big to survive. This was probably a great survival strategy during the earlier lusher jurassic but evolution had to put the growth breaks on saurapods once the climate became drier.
