Hey I herd Godzilla music your a g fan yay

Gojira54 what timestamp?

could it be that Spinosaurus actually walked like the 70s dinosaur movies, upright while dragging its tail?

@@jh5kl Good see , man ! It obviously DID walk upright , and of course did NOT drag it's tail . It could hold it's tail up just as much as a cat or dog ! D. .😌

spino 2100: is a futuristic creature sent back in time to confuse paleontologists who had access to modern weapons and could shoot lazers out of its eyes

*Valstrax intensifies*

2050 Spino, cubs are actually bigger than adults

Zebimicio 2080: Optimus Prime

Spinosaurus 3042: Mother fucking Wyvern with robot arms, a split in half sail, and was able to transform into a Mallard Duck.

It literally was. It was the king of its environment. A swampy, full of deep lakes and river. Inhabited by car sized fishes that made up its diet.

Yeah, now you’re getting it.

Dinosaurs are just dragons without powers

Yep! And they will soon discover that it spits fire, as it has tapered and spacious teeth useful for propelling flammable gases. Logical! ;)

@@gregorysaugustine5236 kings don't have to adapt to eating fish after loosing territory to other carnivores. King? Pshhh.

hahahaha

Oh no the kangaroo model is coming back

The scariest thing about this posture is how tall it would make spinosaurus look. It already looks tall given how it’s sail puts its height higher than all the other mega theropods but if this thing walked like a Therizinosaurus it would really tower above everything else

@@ryaquaza3offical Absolute Unit

Holy hell, the thing would have been unironically one of the tallest theropods ever... Hell, its very likely it would have been THE super-predator in the region and basically untouchable when fully grown.

Who nows? Maybe it’ll make an appearance in 2020

With these amount öf reconstructions? I'll bet a re-interpretation at the end of 2020 Or mid-2021

Maybe but only time will tell that & if we find something new again like the missing arms

Everyone is an idiot now...

@@tnb4509 well no you can still be right or wrong, we just won't know

Nice shout-out.

Deinocheirus, therzinosaurus and quetzalcoatlus: am I a joke to you?

Actually the s-shaped neck is nearly if not entirely universal in birds. Since all birds are descended from theropod dinosaurs then it's a reasonable assumption that most theropods also had an s-shaped neck in a neutral position.

Imagine a Spino standing realy deep in the water, streching his neck out like a Harpune to an unaware fish

On land, sure. But while swimming?

@@amandaburnham8626 True, the question is how much of an s-shape.

Craig Carmichael plesiosaurs had extremely stiff necks though?

One key difference The spinosaurus is awesome and the sequel trilogy is a hot garbage fire in a trash compactor

@@bastionunitb7388 agreed

Probably more like Maritimus*

😆

A 95million year old teenager 😂

*"ITS JUST A NEW PHASE, MOM!"*

It looks like it was evolving towards a croc-like bodyplan.

Agreed; the Quadrupedalism theory was far too sprculative and the Spinosaurus legs were robust enough for a compotent bipedal locomotion when it switched to Terrestrial habitat

Say that to a gorilla's face.

+ Tangerine Dream from "Risky Business" at 17:00 .... made we wanna have sex on a train.

The fucking music made me actually think the news was gonna be that the spinosaurs had genetic connection to Godzilla...

I'm glad someone else noticed that.

Did I hear card series?

Jackson Gabbett yep! It’s going to be a card game similar to Pokémon, but the creatures will be prehistoric animals. All of the animals will look like how recent scientific discoveries depict them.

@@calvarankingofthewest3555 And when will these cards publish and where to buy them?

Yau Tv I am not sure as the designs for the creatures are still in the works. I’m currently in the process of figuring out what species to do, what their attacks will be, and their colors.

Yau Tv also I’m currently selling them at my High School to make some money before I graduate. Afterward I’ll probably make an Etsy shop for them.

Lol same here

I'm waiting for he day they find out that we had a transition and the thing had evolved eventually into a dino-whale. Meaning that Spino we have now could lead to an entire line of therapods that left the land almost entirely. Or it could have just died out...

@@AngelEmfrbl That would be amazing if the river-dwelling Spinosaurus had descendants that took to the sea as the wetlands started to dry up.

@@AngelEmfrbl to me, it looks more like it was converging on crocodile morphology, not necessarily whale (Ichthyosaur, I guess) It's limbs were still fully formed, possibly webbed, diminishing in size but not necessarily heading toward vestigial or flippers. Who knows, maybe it was heading toward a theropod seal body form

And radioactive blood.

@@nicholashaan7345 and a 69 inch.......................................................................................................................................... Index finger

Toostig cool

I'm on there... Pointing out the diagram shows what we have, thus confirming the short hind legs.

Better yet, several full articulated skeletons.

We need a real spinosaurus

@@EmperorHerpes *JP theme*

Considering what we have thus far... 😅 That would result in a even more freaky Dino.

It was...

@@svenheuseveldt7188 I know I am trying to clarify too the others.

@@williamoldaker5348 it was fully aquatic

Did Ibrahim estimate a mass of fully grown individuals in his latest paper? If so do you know what it was, or do you have a link that gives acces to the full study?

@@svenheuseveldt7188 He doesn’t seem to give an estimate for larger specimens in the study given that they focus on an animal the size of the neotype when doing their GDI calculations. So I guess if one wanted to figure out the mass of a larger individual you’d have to essentially scale up from the measurements given for the neotype. Not sure if both of these links work but this should be the full paper about the tail and the supplementary material that shows the weight and CoM estimates : www.dropbox.com/s/2uq3gk72ua8oy7b/s41586-020-2190-3.pdf?dl=0 static-content.springer.com/esm/art%3A10.1038%2Fs41586-020-2190-3/MediaObjects/41586_2020_2190_MOESM1_ESM.pdf

Unknown. That can’t be answered without new material.

Well it could be possibly as the spinosaurus is still considered the largest Land Carnivore, so adding more to that, I wouldn’t be surprised if it did out weight Scotty, really making it the largest, I determine Largest with, Size, Weight, Length, Height, which spinosaurus has more on then Trex Scotty, Scotty is heavier but not longer or even taller, So like I said I wouldn’t be surprised if it does weight more.

Spino boi Coming For That crown from rex

@@reezee2317 except they had different domains. Spino the river dragon and King of his waters, but rexy us a forest dweller and King of that. In water, rexy would be hugely disadvantaged, all spino has to do is force its head under water and hold his neck still, it can even out swim rexy and would have a easier time getting away then rexy has on land, and unless rex can bite spino his not winning. But on land, spino likely was too slow and rexy had a nasty bite. Mostly it would be a case of using weight to spin is advantage and spino only move is similar to a sumo wrestler. Otherwise rexy wins 9 out of 10 times at least

Did you have a stroke? Yust kidding😂

+Mesozoic Scar We have *plenty* and I mean seriously a Lot of Evidence and studies that point out that the Spinosauridae were Generalist Carnivores instead of exaggrated piscivores. For example the recent study about the Spinosaurinae Irritator - a very closer relative of Spinosaurus - concluded the Spinosauridae especially Spinosauridae as Apex Predators of their habitats The research done by Aureliano and colleagues They presented the the food web of the Romualdo Formation. The researchers proposed that spinosaurines from the formation may have also preyed on terrestrial and aquatic crocodyliforms, juveniles of their own species, turtles, and small to medium-sized dinosaurs. This would have made spinosaurines apex predators within their ecosystem. Source Semi-aquatic adaptations in a spinosaur from the Lower Cretaceous of Brazil Another example from another Spinosaurinae - the Siamosaurus - has been found in the Sao Khua Formation of Thailand, tooth crowns from Spinodaurids have been found in *direct* association with sauropod remains, indicating possible predation and scavenging Source The *x* of the Matter: Testing the Relationship between Paleoenvironments and Three Theropod Clades These cases are seperate from the famous Baryonyx ate Iguanodon btw So I could easily answer first two Questions Spinosaurus was very likely indeed capable of consuming terrestrial prey dinosaurs as well as large pterosaurs in addition to crocodyliforms and multiton white shark sized fish And second question The Dilophosaurus indeed suspected to be a more diverse eater Again the specilalization and piscivorous theories are exaggrated but the forementioned theropod likely eat both Terrestrial and Aquatic animals

+Mesozoic Scar there were quite recent studies done about the Tyrannosaurus itself and the results show that the animal was quite slower - should be expected with all the weight tbh - I can share the studies if you want Additionally I have more studies about Spinosauridae bite and bite force estimations

@@thedoruk6324 thank you very much

@@strzygon5426 You are very welcome! 👍 Let me know if You want to see more studies

There probably wasn’t any terrestrial prey for Spinosaurus to hunt to begin with. Predatory theropods vastly outnumber herbivorous dinosaurs in the Kem Kem, both from skeletal and trackway evidence.

The humerus is about the same size as the femur as well. Perhaps it used its forelimbs extensively when traversing rough ground in a coastal habitat, in much the same way as a human will.

Maybe, its been quite some time since I looked at this comment and it seems this creature just keeps changing. I believe this original comment was before we even knew it had a paddle tail@@highloughsdrifter1629

+DragonFae16 That'ld technically make the Spinosaurus to equalavilent to the modern Crocodilian species like Orinoco - Slender Snouted - Nile and Saltwater crocodiles - which are very gluttonous and opportunistic predators

It would have to be smaller for that strategy to work, or live in deeper waters.

Agreed, too many people comparing it to least likely animals instead of the closer relatives for theropods aside from rather derivered avians

They have, it did not help.

Crocodiles are built differently.

@Boi! Nice interpretation I agree that the significant advantages in height - the existence of functional arms & claws make The Spinosaurus a potential opponent

@Boi! Yup, I certainly agree to that

Claws, tail, jaws. Look at crocs, but think of the bonus claws while taking out the spin of death.

@Boi! milbournes theory is extremely interesting and deserves more recognotion

@@AnonningAnon The arms with slasher claws would cause immense injury even death We have no idea how muscular they were or how keenly/strongly Spino could deliver them

Due to their Suze most other creatures would leave them alone. Its why lions rarely go after rhino's, elephants and hippos while zebra, wilderbeasts and antelope are around. The sail wouldmake it even more massive looking.

I don't care what you believe, only what there's evidence for, which is plainly laid out in Hone & Holtz 2021.

Its "Encased in Amber" from the same artist

+Richard Renes Precisely! The Morocco Spinosaurus subsepcies could also present significant differentiations compared to Egyptian & Libya Subspecies, albeit the 2010 isotope analysis established; for the morocco spinosaurus; that it did spent a significant part of its life around terrestrial habitats as much as water

I forget which paper it is but that idea was recently put forward, I believe the researchers also argued the somewhat poorly known South American Spinosaur Oxalia might also be a member of this Genus. Kinda like how Sarchosuchus is found in African and South American fossil beds, Africa and South America were still lightly attached 110mya if I recall right

+Safton Quite Possible!

That wouldn't explain the comically short hindlimbs and it's clear aquatic diet.

@@Deform-2024 I severely disagree on the clear aquatic diet part as there is literally confirmed fossil evidence from two differentiated Spinosaurinae (closest species to Spinosaurus such as Irritator and Siamosaurus) that the Spinosaurids being Generalistic Carnivores that definetly consumed dinosaurs and large pterosaurs The legs also likely %25 longer than first depicted on 2014 NatGeo publishment and are robust. You could check out the fossil pictures on google

@@Deform-2024 True, either way, spinosaurus is one very weird theropod and will continue to surprise us all

@@thedoruk6324 There is only evidence Spinosaurus ate large armoured fish, not dinosaurs. It could have hunted for dinosaurs that were swept out into the river, but that is speculatve. Plus, Scott Hartman's 27% leg increase was long ago disproved by Ibrahim.

Carnotorus arms

@@Algeriawindows69 lol

Heavier than that.

@@Deform-2024 the NHMUK R & the undisclosured humerus would also likely Make the Spinosaurus longer - 17m perhaps ?

@@Deform-2024 yeah, apparently according to Ibrahim in a recent Q and A,under the new reconstruction the largest specimens could reach 10 -12 tons , which if accurate would truly make Spino the largest known theropod by a considerable margin.

It's body is too dense to float for long periods of time.

+Shawn Charton In addition Michael Milbourne compared the elongated tail spines to Basilisk Lizards and Phillphines Sailfin Lizards rather than Salamanders or tadpoles

@@thedoruk6324 pustulatus = Philippine sailfin dragons. :-)

@Boi! People should really be aware that the NatGeo is prone to exaggrate and show inaccuracy, especially on the matters of paleontology They were the ones that propaganated the quadrupedalism despite the non-existent evidence

It was never ever confirmed to be hybrid, that was a theory
