Also yes, my editing is ironically at its absolute worst on my most popular video…I beg you, please watch my other content just to know I’m not this bad 😂
The funkier spinosaurus gets as we learn about it, the more I've come to love it.
How is THAT an inefficient swimmer yet T-Rex is believed to have been able to swim just fine
Sounds to me like a hippo hippos are to heavy to swim they sink and run along the sea or river floor and then live most of there life in water
Ok but nothing about a T-Rex looks like it can swim, let alone so effectively, it was as dangerous in water as it was on land.
At least a hippo has nostrils and eyes on the top of its head, even weight distribution, and 4 equally strong limbs with webbed feet.
Edit: which is why they can not only run along the bottom of their water pool, but also swim to the surface just as easily.
We’re to believe the Spinosarus wasn’t water loving??? Like, how - where ..what part of it doesn’t look like it can’t swim? What part of its mouth looks like it’s not made to eat fish? Its claws are literally made for spearing and scooping.
Whoever said this thing wasn’t a water Dino is a certified idiot. Period. Any fool could look at it and clearly see that it was.
This is the worst debate in history.
swim to hunt and swim to travel are 2 different things.
When you’re right, you’re right.
But what point are you trying to make? (Not being a smartass)
There’s no reason to believe ol spino-boyo couldn’t/didn’t do both..
If a male brown bear can swim nearly 5 miles to cross water and hunts what’s in/around it…..and so did T-Rex ..then this guy, who looks everything like an animal that treads water & ate what was in it, did too.
@@gic8849One of the reasons its thought to have not been a good swimmer is because it was too buoyant to go underwater and even if it could its sail could cause a lot of drag. It almost certainly could swim on the surface and it definitely lived in shallow water but it was no where near an fully aquatic species.
I am on the side of the delta argument. Assuming it lived in shallow water, banks etc , Based on that assumption I feel I have had an incite I've not heard anyone mention.
As a tropical fish keeper I have long since changed all of my white nets to black ones, because I realised that when you try and catch fish with a white net the fish will do anything it can to stay away from it, but if you use a black one they are verry likely to dive into it.
Fish when they cense danger are programmed to look for cover. My theory is that like a panther they probably had favourite perches were they used their sails to create shade so when they moved for the strike the fish would head for that shade. Predictive strategies like this are common in nature.
I did not want to make my first point too long.
Those laterally flattened tails that have been largely responsible for the fully aquatic theories, according to my "Insite" could be used to create gentle eddies to to coral the fish into the Strick zone(I in fact use a two nett for the strategy same thig.).
I note with interest Dino-gen's news on the latest research showing that their jaw shape would have given the least resistance to a side swipe through water. which if I'm right would be towards the shade created by their spines.
3) My speculation one step further .
It is likely that different individuals favoured ither left or right sides. I wander if that could show up on their musculature /bone development?
That's a really interesting theory actually! I'm not a fisher myself but I've heard that shaded spots are the best for catches, so it does make sense. As for individuals preferring a side, I can imagine that, whilst there might have been preferences, any differences in musculature on either side would be too small to conclude, since they would need to be good at doing it from both sides. It also doesn't help that finds are simply not complete enough to read this kind of info just yet.
Wow!...
That's a really nice bar ya got back there...
Thanks, it is most certainly a prized possession 😅
Sir is upping the budget. Big up.
Imagine millions of years into the future and they find a giraffe fossil. They will have no clue how it managed to stand up and support itself. Let alone being able to galllop like a horse! Great video m8, Spino is such a fascinating mystery, wait until they discover it's wings! 😂
Thank you, so glad you enjoyed the video 😄 to be honest, I always find imagining todays animals millions of years into the future being found and what they would make if it. Really puts into context how much we don’t know!
Spinosaurus plays poker with Elvis in his hidden base in Area 51.
😂
I remember being in the Theater seeing that BEAST of a Spinosaurus tear up that Tyrannosaurus and to this day it is still my favorite dinosaur of all time especially now with all the new information we keep getting from it!
I loved that annoyed "for once". That really made me laugh.
Great video on this intriguing Dinosaur. The large sail i believe probably served a function as a display item. To attract a mate aa well as warning off others of its kind. Perhaps also as a means of regulating its body temperature. 💪🏻✨🙏🏻
I have colleagues that study in the extinct animals faculty. We always tend to agree that the whole reconstruction is an *amalgamation* of different genus and different sized individuals (As other professionals have mentioned it to be a chimera during the 2014 reconstruction). What Nizar Ibrahim and his team did was scale the juvenile neotype to the largest dentary piece (MSNM V4047) leaving a large marginal error room in terms of scaling (hindlegs, vertabra etc). They also concluded that Spinosaurus B, Spinosaurus Maroccanus, Sigilmassasaurus and now Oxalaia as *Spinosaurus Aegyptiacus* which is a very bold conclusion. The entire anatomy and reconstruction conclusions were already debated in the SW Evers 2015 study and still is to this day.
With the recent study regarding a detailed bone density by Matteo Fabbri, we had a lot of news that surprised us. Baryonyx had very dense bones (denser than Suchomimus actually!) which is now being discussed that maybe Baryonyx is more similar to the Spinosauridae family than the Baryonychinae subfamily.
Baryonyx dorsal ribs had a density of *0.94* , Spinosaurus was around *0.97* while Suchomimus was about *0.68.*
Carcharadontosaurids also had respectfully dense bones of *0.80* while Tyrannosaurus having the most hollow bones of the large theropods at *0.65.*
A similar reconstruction to Baryonyx would certainly fix some issues but we still have the question of which fossil belongs to which. The best place to get more information is towards the origin of it's discovery (Egypt) but that's going to be proven difficult due to the harsh environment conditions and permit affairs. All in all, the idea of this Spinosaurus reconstruction is becoming more skeptical and seems to bring up more questions than answers. We do need more material but we also need new theories. All we know is that Spinosaurus had very dense bones and it was the largest terrestrial predator. We'll have to wait what Nizar Ibrahim's team reports since he has these fossils in his position. Last we anything from him was this creature was 15 to 16 meters long (50 to 52ft) and weighed over 10 metric tonnes. We need to see his new and improved model and maybe others can challenge it fitting that size.
That's awesome, thank you for the insights! I must admit, I didn't know the bones of Carcharadontosaurids were quite so dense, it certainly brings up more questions.
FSAC-KK-11888 was 60 to 70% complete and was proven to be one animal, there's no reason to assume it's a chimera. Ignoring MSNM-V4047 and NHMUK VP R-16421, you still have a 10 meter theropod with hindlimb proportions of a 7 meter one.
Well until a complete set of fossils are found we will never know for sure.
If we find a complete skeleton knowing the Spinosaurus's history it will prove every theory we have ever had wrong and Paleontologist will have to figure it out again.
Just found you, and I'm liking what I see. Adding you to my list of smaller paleontology channels, for sure!
Awesome, thank you!
Good vid. I'm down with the heron theory but not so down with the swimming. There was one other critter that Spinosaurus shared it's environment with and that was Sarcosuchus. The other apex predator. Lots of apex predators in the Bahariya Formation. You were definantly not safe anywhere.
You know, the more I learn about the world the dinosaurs lived in, the more it's...weird...that scientists initially thought dinosaurs were cold-blooded and often too big to live anywhere but a swamp........to a time when scientists imagined dinosaurs were warm-blooded and did NOT live in a swamp..........and now it seems a lot of dinosaurs lived in and around swamps. But were warm-blooded. 🦖
Amazing, right? The diversity of these guys never ceases to amaze me 😃
A hot guy talking about dinosaurs. 💯
What? Where?!
Spinosaurus went from a boring tyrannosaurus ripoff to a beautiful water dragon.
Spino fans should be happy !!
I was old enough to watch that movie and the first 2 Jurassic park movies not all of us that are into dinosaurs are born in the 2000’s hell I graduated in 2006 and all I wanted to do when I was a kid was be a paleontologist now I’m 36 and going back to school to be a paleontologist
Good on you man, I also had a few of working jobs before I wanted to head back to to qualify in palaeontology, so I know how much of a big deal it is to pluck yourself out to go back to furthering education, proud of you 👍 …I’m also hoping to be a Dr Hughes in the next few years so small world eh?
I have a hunch that Spino would operate like a kind of flesh sailboat if it wanted to; a large and likely inflexible paddle tail with a shape like that actually kinda sucks for sustained propulsion, but as a rudder I can see it.
Alternatively (or perhaps in addition?) I remember some suggestion it may have actually moved across the actual bed of the river while hunting. But fuck knows at this rate.
A rudder! Of course, why didn’t I think of that?! That’s a really great suggestion 😃
4:55; Wrong!! Only all fully BIPEDAL Dinosaurs on JP have "broken wrists". :)
JP3 spinosaurus is iconic🙄💯😍
🎶 we don't talk about Spino 🎶
Ibrahim et al has many studies in the pipeline that will answer the many questions people have on it's ecology. Real swimming simulations, terrestrial biomechanics, braincase analysis, among others will release over the next couple of years.
Looking forward to them 🤓

It's not a "Submarine" or "Boat".
It's a "Torpedo".
I did a paper on this.
First of all, with proper coloration, texture, movement, etc, the uneven sail could have made it appear to be a patch of marsh grass or something, breaking up it's profile to prey or predators. Maybe it even waves the sale a bit, making it look like waving reeds or grass, ir even bushes. Maybe prey items would even approach it for cover, or to feed among the faux vegetation.
Strong short legs, like an alligator could have propelled it forward in a single, sudden ambush lunge. Like a huge rocket with a wide open mouth full of teeth.
The flat tail would have been useful as a one-time "rudder". Once the rocket shoots away at its prey, legs are tucked in against it's body. The tail would give it one opportunity to turn that huge, rocketing body left or right during that small window of high-velocity. Last-second redirection. This technique would be highly effective. A one-shot attack. Not much endurance needed. If it misses, it just glides a little bit away from that spot. It sets up, "reloads" and its ready for the next prey item.
It's a "Torpedo"
Fascinating, thanks so much for the insight 😃
@@dino-gen - I enjoyed your video and reading through all the ideas in the comments. Smart, interested people with smart, interesting ideas. Lots of fun.
@@atilax6452 I fully agree, so glad you're enjoying the content :)
Spinosaurus is only an inefficient swimmer IF the prey it hunted was faster than it. It's bit like saying BMW is a bad car because it's slower than a ferrari.
Obviously it was good at hunting something because it lived for a few million years.
I think there is no need for Spinosaurus to swim fast enough, just like fish will always faster than crocodiles. Spinosaurus just needs to hunt effectively. It's like a water monitor lizard fishing. When we compare the body structure of Spinosaurus and Water Monitor, do we think that Spinosaurus is worse at swimming than Water Monitor?😅
This much is true, Spinosaurus was likely an ambush predator like today's crocodiles, which makes up for the lack of speed. With regards to the Water Monitor though, while the body plans are similar, they are not identical and any similarities become more and more irrelevant the closer you get to Spinosaurus's size since it would have a lot more drag to contend with.
@@dino-gen Thank you Gen！We know the largest animals don't seem to be the fastest. Because of the resistance relationship. However, an animal's physical size cannot fully predict its locomotive efficiency. Larger animals also have a larger range of motion, and greater muscle mass provides better explosive power, which makes up for the lack of speed. The crocodile is considered to be large among living animals. It usually moves slowly but can be very fast when hunting. I imagine Spinosaurus is about as efficient as a Crocodile or water monitor. The speed is proportional to its size, giving it an acceptable swimming movement speed.
@@dino-gen A lot of people find it difficult for Spinosaurus to swim well, a large part of which is that its neural spines are a hindrance in swimming. Indeed, when the neural spine is submerged in water, it is not hydrodynamic, and the current can easily fight against it and cause it to roll over. But it's possible that its spines were barely submerged in the water as it swam, but instead floated on the surface like a sail, like the approaching shark in the movie. In this way, the part of Spinosaurus submerged in the water is very similar to that of a crocodile, and its swimming style is no problem.
They were like part hippo part crocodile. They would have to have been ambush predators.
I sort of think spinosaurideas are related to herons storks and pelicans but good theory
nah man they are transformers paleontologis are just ashemed to adimit it after taking soo long to realise
All organisms are related.
I clicked on this vid just to make sure Trex is still king. 😪
Well, I'm glad you did! And to think you were worried...
No, it's the Dynamosaurus. :)
Wow
I feel bad for the Spinosaurus, it is my favorite meat eating dinosaur
I´m the 69th upvote.
A new paper show that spino legs couldn't sustain its body. The scientist who found specimen with legs was reluctant in stabilish the various parts as the same animal. I particulary think that the tiny legs are a mistake and spinosaur have legs much like suchomimus and barionyx. I think its kind impossible that a such big animal with a massive handicap like a sail that was probrably used for sexual selection gás such lugish mobility. Like he probrably cosume a lot of food to sustain all that, the enviroment have a huge indicativeto benefit a piscivorus diet, plus they have the competition and treat of others huge theropods and crocs. The spinosaur specimens were always controversial. Its time to be a bit more skeptic and try to find new bones to answear that, LEG BONES.
You mean the TWITTER thread from an artist who never published a real study before?
I feel sorry for you spinosaurus
Spinosaurus is one of the weakest dinosaur that ever existed , one of the most bizarre & overrated dinosaur
Its not weak even thought it only eats small crocodilians and onchopristis,other fish
It could kill at Rex if it wanted to and lived at the same time
@@Acro323 it cant kill a trex its kinda common sense
Not weak but lose to rex and giga
@@loulouthebabarianalleycat4189 yes weak & lose to not only Rex & Giga but many other Theropods also lose to against something like Torvosaurus also
