If the mass of a 36 feet spino is 4 tonnes, then that would mean a 50 feet long spino would weigh more than 10 tonnes, from scaling using the square cube law. That would make it the heaviest theropod surpassing even Scotty the rex. Are the weight estimates correct for a 36 feet spino or does the animal become more gracile as it ages?

[@EDGEscience]

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.

If the new evidence runs counter to previously held hypotheses or theories, it gets tested. If the new evidence is found to hold up better than the old evidence, the paradigm shifts. And the people who liked the old version better have to suck it up and accept that it was wrong or try to find more evidence to support a modified version of the old paradigm.

I have read quite a few articles about the flexibility of the spinosaurus tail. However, I've yet to read a single one that mentions my theory. Correct me if I am wrong and I'm always open for discussion. What if the spinosaurus did not simply just rely on its tail and as of recently MAYBE also its webbed hind feet, but rather swam much more like that of a snake? Using its entire body as the propulsion system, including that all famous large sail. I suspect that the tail would not need to be as flexible if it swam in this manner as the large neck and side muscles were doing all the harder initial thrusting for propulsion.

[@thedoruk6324]

+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

What I wish you would have done in one or both of these videos is mention the environment that this creature would be been surviving in. At the time, this area of north Africa would have been covered in water with the coastal areas being host to swamps and numerous river deltas. This paints a much better picture to why the Spinosaurus would have been semi-aquatic. I would imagine these large rivers and lakes near the coast were probably where these animals thrived since many large fresh-water fish also lived in this area during the Cretaceous period.

[@andrewszigeti2174]

Given how short those legs are, how long and heavy the the tail is, and the lack of structure in the tail locking it into a horizontal position like most other therapods, I rather expect Spinosaurs were tail-draggers much like the modern crocodillians. Now whether they kept their spine mostly horizontal, or if they assumed the old-fashioned 'tripodal' stance common to early 20th century therapod reconstructions, that question I leave to the professionals.

[@chissstardestroyer]

Well, the tail mass you're talking about would definitely help to balance the body weight, even if the total animal weight was closer to eleven tons, which's said to be the uppermost weight limit of said animal. Also, the hand bones wouldn't support walking on all fours, and the claws on the hands don't match with that overall format; but their format *does definitely* fit with a very blended diet of both fish and meat of land animals; so it was probably a generalist predator that ate just about anything it ran across that would fit the easiest food source available. Now, the tail bones do match a very flexible tail to the degree that fossilized land crocs show, but remember, bones aren't flexible, but what are are the muscles attached to the bones, and bones in that arrangement are small in the amount of motion.

[@od1452]

Thanks. Very interesting. Could the tail indicate a water way slow troller that used its claws as a way to help it find food? Maybe even looking at the shores of water ways. ?

Looking at what you said one thing caught my attention. Spinosaurus could easily stand still up straight on two legs when its legs where straight. It could pick up large fish to while standing up. The issue is that whenever it has all its weight on one leg, and its not in a straightened position. In other words climbing even a simple hill would be a big challenge for it since when you walk one leg is off the ground and if you are climbing even just a gradually incline your leg is not going to be straight. So basically it would have to use its arms to help it climb.

What if hatchling/juvenile spinosaurus had more flexible tails and were more aquatic early in their life, and as they aged, grew more terrestrial and a stiffer tail?

[@retregratotherversrsentre7727]

+Safton Quite Possible!

[@Deform-2024]

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

[@thedoruk6324]

@@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

[@safron2442]

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

[@Deform-2024]

@@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.

[@Voltorb1993]

Goddamnit, whenever I take my eyes off of Spinosaurus for a minute, it always looks different when I look back.

4:34 - Heh, "neck meats". Was that a _Napoleon Dynamite_ reference, an _Invader ZIM_ reference, or neither? 😁

fire force op in background ? 6:14

[@DragonFae16]

Maybe the tail was used more as a rudder, with the legs acting as the main propulsion. After all, no-one ever said it have to be a fast swimmer. It could have been an ambush predator.

[@thedoruk6324]

+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

[@introspectiver1787]

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

[@colinsmith1071]

the intro rocks!

[@its_kintama1109]

i hear inferno from fire force! great vid btw, very interesting

[@thatoneguy7781]

I find it interesting that despite finding more fossilized parts of the spiny boi it only kicked up more debate

[@Springy05]

I knew it! I knew the new tail would help have a more bipedal stance! I just hope all this convulution with spinosaurus ends soon. I love this animal so much, and I hope we finally can agree with a definitive stance and look for the animal

[@nerdcrocodile4956]

Love this channel

[@berkerden2875]

Me too

[@hectoralvarezrodriguez7045]

Such an interesting dinosaur, I hope more new information be discovered soon. Would be cool a video about other members of spinosauridae. There is evidence of ichthyovenator have a similar tail isn´t it?

[@thedoruk6324]

I wouldn't say solid evidence as the new identified 'material' appearently isn't very solidified

[@cralixthegameking4408]

Is it possible that the dip could be caused by damage to the sail early in life or somthing simmilar

[@shinygolisopod1407]

3:49 Hooray i like the spino bipedal more so than quadtraped it looks more threatning

[@lanewaldon6450]

I definitely agree and feel like the sail formed a round non dipping sail, idk why it just looks a bit more natural but then I realise oh wait what about the legs? But with the sail on the tail wht smaller legs make sense if spinosaurus had a somewhat chonkier tail like a crocodillian. But I do think the tail would have to be flexible or they'd be kinda f#cked in something such combat and competition for a mate

[@AngelEmfrbl]

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.

From 3:45 untill 3:55 the animation is done by SpinodragonProductions but the model is made by bARTek. Here's the link: kzbin.info/www/bejne/n3OQY6eVjciVqLs (I just wanted to put that out there; it was a free download so it wasn't stolen)

What is this newest paper you are referencing? Could you give a link? Thanks!

[@roarzasaurasrex]

What's the song from 8:42?

[@GippyHappy]

I swear the next big discovery is going to be that Spinosaurus didn't even exist

[@anthonyfareri8006]

And do u think spinosaurus wear the same color like crocodiles or do you think they were different individual colors

[@southbeachmiamiart895]

There should be more fossils out there. This animal loved water. Imagine how hot the equator location around the world was back then. That's what I'm saying, there has to be more.

[@xxthexcaliburxx]

I'm just waiting for the moment where it turns out that its just a big fish that had wings and flew

What’s the music in the background at 1:52?
