I don't understand why everyone is so annoyed by this debate. This debate is a perfect representation of a *core principle* of science! I would even argue that it is *THE* core principle of science. Much like in a courtroom, two sides (or more) take different stances on a given subject and relentlessly nitpick each other until one side can no longer refute the other and a conviction can be safely and confidently concluded. The team which claims that spinosaurus didn't swim is forcing the team who claims it does to come to the table with irrefutable, unambiguous, and entirely logically sound proof. With every flaw they find in the swimming hypothesis, they only strengthen it. Both sides will get stronger and more evident until one beats out the other by being infallable. This is *good!* This is what science is all about! Without debates like this, where a team or individual makes claims that seem outlandish to the scientific understanding of their peers, we would not have known that birds were dinosaurs. We wouldn't have even known that a meteor took out the dinosaurs! Spinosaurus is my favourite dinosaur. I know it's many of yours' too! Sit back and enjoy the ride, because at the end of this we will know what is *most likely* the truth!

You would have to compare other animals or dinosaurs that would be able to swim and hunt on land the choices are slim and the spinosaurus are huge the chances for it to do both would be like a freak of nature and be vulnerable to attacks because of bone density.

[@horvathbenedek3596]

"Much like a courtroom" Problem is, nobody asked for this dichotomy. You have one "team" as you put it making rational inferences from very much factual evidence... ...and another team splitting hairs over definitions ("uhm, actually, it's AT BEST semi-aquatic, because it couldn't swim as fast as a crocodile!"), ignoring or discounting said hard, factual evidence ("the tail was for mating display"), ingoring very rigorous and hard hitting, but not necessarily in-field research (I guess the "bipedal heron Spino" team just collectivel, chose to ignore that every computer simulation or regression model concluded this animal was incapable of standing on its own two legs, let alone walk around), and just being petty and difficult in general ("huh huh, it would have turned over in the water, so it couldn't swim! I concluded this by drawing a 2D image, and taking its center of mass without any regard for the actual physiology of the animal! I is smort!"). The problem with this entire debate is that literally every argument I saw presented from the land-based bipedal heron-style Spino side was textbook junk science. Seriously, as an engineer it baffled me that Paul Sereno seriously released a paper arguing that Spinosaurus's center of mass COULD have conceivably been over its legs, therefore it was bipedal... without ever actually creating a 3D finite element simulation of the animal, which would have uncovered what is plain to see, that the spindly legs are incapable of supporting the body, much less exerting enough torque to keep the torso and tail upright. If your idea of a scientific debate is someone making actual argument, and the other strawmanning it and randomly rambling though... then I understand your position.

[@predabot__6778]

@@horvathbenedek3596 So, is it generally considered that the aquatic or semi-aquatic theory is the one with better and more solid evidence at this point? On another note, I'm curious what the take on Spino's HANDS and knuckles are at the moment - because I saw some evidence that suggested that it would be a... knuckle-walker?? So, a swimming heron-crocodile that, when it rarely comes on land, slowly waddles and occassionally supports itself slightly on its knuckles. Knuckles which are of course held like a theropod, so they can't rotate them 90 degrees, but have to use a fairly narrow space as support. Has this been debunked? Is the general idea that it almost never went on land? Because I think the consensus here is that this sounds like a fairly immobile animal on land - possibly at the level of a seal (so no croco-duck... :'( ), and certainly worse than most semi-aquatic crocodylians. Side-note: what would it mean if Spinosaurus really was bad at diving and pursuing prey in the water, but also terrible at land-locomotion? Seems like an extremely niched animal, with a very vulnerable ecology, where the slightest change could lead to its extinction.

For how big spinosaurus is and how big it’s pray likely was, it likely still had to reach pretty deep level shallow waters, like 2-3 meters(where it can still at least stand) But, since some fishes like onchopristis (dunno how to spell it) sawfish and other lung fish like to hang out in more shallower waters, Spinosaurus likely didn’t had too travel Far, but it’s tall size would still at least likely have helped it better.

[@predalienplush780]

There's several problems with that. Why have nostrils further up on the head if it's going to be submerged? Reduced limbs, if those legs aren't chimeric or from a young specimen and actually belong to an adult Spinosaurus, are not the only trait of a formerly terrestrial animal adapting to an aquatic lifestyle. While we barely have any fossils of it, aquatic animals usually have a large chest to support massive lungs, and Spinosaurus's ribcage seems to be quite narrow. Not to mention, why have the sail if it's a submerged predator?

[@antimatterhorn]

@@predalienplush780 spinal extensions for sails aren't usually big flat tongs like what spinosaurus has. dimetrodon isn't a dinosaur, but you can see fairly well what a sail support structure looks like on one, or a sailbacked lizard. spinosaur vertebrae look a lot more like what you find on "humped" animals, like bison.

why not compare them to marine iguanas Granted their herbivores but still they have some of the same adaptations strong clause to grip the subsurface peculiarly designed it draw structure to feed a flattened tail to give them power the ability to streamline their arms and legs to reduce drag when swimming in the water I can't think of anything else other than maybe a dorsal ridge For helping for not for propulsion but for stability now the other thing I always figured that the dorsal spine on spinosaurus will be used for is when they're in cold water it reduces their efficiency in feeding and digesting therefore the soil sail is solely there to provide a heat exchange To warm them up so that when they're feeding they can digest right away instead of having to wait to halt out of the ground and warm themselves back up again I mean granted they're probably warm blooded but still you're going to get cold and cold water water sucks away heat like 10 times faster than air so if they can heat themselves back up again while feeding that's an advantage.

Given that most of the scientists agree that Spinosaurus lived in an area that likely a riverplain or swampland, similar to the European Baronyx, but the sail or "hump" suggests that it may have suffered through periods in the year when food is scarce, therefore the need to travel through the swampy areas (either from flooding or dry season) to get to the rivers. The streamlined body may be for wading in deep water, and allowing it to travel up stream without having too much drag or to move around trees in a flooded forest. I can't work out why they are fixated on whether it was an "active" hunter, as its would be difficult to hunt underwater with its body shape.

[@somechannel7235]

Based on what I've seen the best conclusion I can come to about how spinosaurus lived and foraged, is probably that is probably more closer to a lifestyle of a stork/heron and a bear. Like imagine how bears wade in shallow water and river banks when salmon are migrating up rivers, and bears come to catch salmon to eat it. That'd make a lot of sense for spinosaurus to do since there's lot of giant fish for it to eat in the waters of North Africa during its time. Or like how storks wade in shallow water where they hunt for small fish, frogs and other things they could fit in their mouth. And depending on how muddy riverbank/the lake/river bottom is, spino having wide feet with flat claws would make sense if it was to help prevent it sinking too much. Like this video already showed it's extremely unlikely that spinosaurus could swim very well, let alone dive. Like it said, it's too "floaty" and it is very unstable and could even capsize to one of the sides, which could be a position where it is difficult for it to get out of if "stranded out" in the deeper water, and if it can't get out of that position it could drown. So it likely spent most of its time in between both land and water wading through, snout inside the water ready to snap up any fish swimming near by for food. And evidence that support that are the dense leg bones and the new long tail, since it's a giant theropod that's like 15 meters long and weighs like 7000-9000kgs on a conservative estimate (could be even longer and heavier since we haven't found a full skeleton of a single specimen, only fragmentary skeletons, all mostly from different individuals from my understanding). So it needs strong powerful legs to move and keep it standing. Also the new giant tail that was found and has those long spines on them has been shown to make spinosaurus much more balanced and it'd move the center of gravity over the hips or slightly in front of it. Which would mean that spino could walk on land very easily and it wouldn't need to resort to knuckle walking or any quadraped lifestyle, which already could be difficult since there is no evidence supporting that it could even do that. (are spinosaurus arms and wrists even strong enough to handle forces that'd be imparted if it did try to move quadrapedally? Or would they just fracture?) Also some might question as to why would it have such a big tail, but do people forget that the reason why theropods have long tails in the first place is because it acts as a counter weight to their huge heads and torsos that are in the front? As lame and as simple as it sounds but spinosaurus could have evolved the giant tail only as a counter weight, which is a response to stay balanced due to their large heads, proportionally large arms and the back sail which make it extremely front heavy otherwise. What I'd want to see is how big the caudofemoralis muscle is on spinosaurus and its close relatives (suchomimus, etc.) because that'd be a good indicator as to how active it's legs would be and how much power it generates. I'm putting this here at the bottom because it is mostly unrelated to the above thing and is mainly just my subjective opinions. I don't want to point fingers, but I'm going to do so anyway. Sorry if I come off as a dick. But to me it feels like Ibrahim and his team have this "obssesion" over aquatic spinosaurus idea, like they want it to be semi-aquatic pursuit predator that swims for whatever reason, maybe they just think it'd be cool. I don't know. Mind, nothing wrong with such ideas. And my evidence for this are the very studies in this video, where Myrhvold points out how lot of Ibrahim's team's recent studies are flawed, kind of all over the place and due to it hardly can be used to prove anything. And then there's the other studies which point out how poor of a swimmer and diver spinosaurus would be just due to how it is shaped, which puts a damper on the pursuit swimmer idea as well. Still, nothing wrong with ideas and theories that are more outlandish and go against the grain but there is a point where it starts to get a bit odd.

[@PhailRaptor]

Legit question -- why are all the relevant parties fixated on a semi-aquatic >pursuit< predator? I'd also like to know more about the test for the effectiveness of the tail sail/fin for aqueous locomotion. What kind of locomotion? The conditions for casual long distance swimming are completely different than the ones for high octane predation. Who's to say that Spinosaurus was a long range migratory predator of some kind of fish species that lived in deep water pools connected by fairly shallow waterways or swamps? Traversing that kind of environment would have lent itself to the ability to cover long distance effectively and for little energy input. Particularly if that prey specie was bottlenecked by a narrow section of river, where the Spino could catch them bear style as they moved through.

You should blur the bad parts of the old Spinosaurus art when not using them in a contemporaneous context.

[@godslaughter]

I have been adamant about this since I was a child and I say Spinosaurus was like a gigantic pelican-stork-duck. Also, from personal experience, only taking samples from femora to determine whether an animal was aquatic, terrestrial or semi-aquatic just doesn't make sense and it is going to draw some really bad conclusions, especially in the case of non-avian dinosaurs due to their undeniable similarities between themselves and birds. Even in birds, who are lightweight, flying animals, their femora, tibiae, ulnae, humeruses, radiuses and even carpometarcarpuses and tarsometatarsi are THICK. They are dense, they are the last bones to fall apart. Their skulls and other bones of their head without skeletal attachment (such as the hyoid apparatus and sclerotic rings) and ribs are the first to start becoming damaged, then the spine (pygostyle excluded due to its density), then the pelvic bones, scapulae, coracoids, sternum, and then you'll be left with the arms and legs. Spinosaurus was an enormous animal who would require thick, sturdy and therefore heavy leg bones to support itself on land. Sunlight, weather erosion, scavengers and decomposition itself damage bones, they make them brittle which is why arm and leg bones are usually the most commonly preserved bones of large dinosaurs, as they last the longest. This is also why dinosaurs such as oviraptorids, caenagnathids, dilophosaurs and some other crested dinosaurs (and pterosaurs!) have such fragmentary skulls. A portion of their skulls is super hollow bone allowing for better bloodflow and healthy keratin coverage. As the body decomposes, the keratin that's exposed to sunlight and water is going to decompose, allowing the bacteria to enter the porous bone and degrading it even further. That's why oviraptorids almost always have their premaxillary and nasal bones (crests) missing, while pachycephalosaurs, ceratopsians and ankylosaurs preserve so well. We don't even know what the crest on Spinosaurus looked like, but we can sorta infer it. Regardless, if they want better data, they'd have to analyse bone samples from every portion of a Spinosaurus' body, which of course is impossible with such limited material. If anything, I'd say the bones of the pelvis, arms and legs of Spinosaurus were thick and robust, the sail bones were lightweight but somewhat robust, the spine was more hollow but structurally solid, the tail bones were super light (makes no sense for propulsion of such an enormous animal), the premaxilla, maxilla, nasal bone, lacrimal and dentary were denser than the rest of the skull, possibly having a keratinous cover, while the other bones were more lightweight but strong, with cranial kinesis as many piscivorous birds are capable of swallowing fish whole. If you take a look at cormorants, pelicans, grebes and seagulls, they are perfectly adapted to very opportunistic and ravenous feeding habits, which is very likely something that Spinosaurus participated in, albeit with a more gregarious lifestyle. I am fairly certain their large "sails", tail and head ornaments were all there for indirect self defense through signalling and implied size, as an injury for an animal that large could be deadly, so having a more peaceful existence among other predators makes full sense, and that's supported by other fossil material of different theropod species and groups, both spinosaurs and others. My hypothesis on spinosaurs being gigantic pelican-storks has not changed, but I really want more data so we can finally put this to rest. Not only that but the foramina on a spinosaurid skull are very similar to the foramina of birds, including pelicans, who have similar maxillary and dentary bones full of foramina for a sheath. Nothing is stopping spinosaurs or other theropods from having both a beak and teeth.

[@barrybarlowe5640]

I find this whole thing amusing. Looking at the latest reconstructions I feel Spinosaurus principally hunted by wading, like a heron or a grizzly bear. I doubt it hunted while swimming. It could swim, though. that high spine was likely a mating display, but also, like a camel's hump, could store nutrition. It could walk on all fours or bipedally. Like bears, it chowed down and stored fat in its hump for the lean seasons, when fish weren't as readily available. During lean times, it scavenged, or ambushed prey, but moved as little as possible, waiting for opportunities.

All the nostril positioning study proves is that when it swam, it probably held it's head in an S shaped bend above the water, like a water bird. You can be semi aquatic without being a whale/seal or crocodile.

@@EDGEscience As are crocodiles and whales. Arguably more so. Regardless there is more structural parallels here. And the fact that the paper likens it to the nostril position of a heron specifically, a wading bird specifically is absurd, as all kinds of water birds have simliar nostril set ups to the spino. If you are going to distinguish from the placement of the nostrils, that if a dinosaur, of all creatures is semi aquatic, I think missing out on semi aquatic birds is a far oversight. And this is my issue with the paper. Like crocs and phytosaurs have their nostrils where they do so that the water conceals them. No-one is proposing that spino was ambushing giant dinosaurs and pulling them into the water to drown them. Personally I maintain that any possible conclusions from the nostril position is the implication that the animal floats more than it sinks, and that it holds it's head out of the water when swimming, like said birds, which would help it spot prey and survey it's enviroment. It's not concerned by hiding from land animals(unless there is a scary big Carchie around with a taste for the sea food...).

@@rileyernst9086 even then adult spinos were not regularly on the menu and more of a danger than not given that we found healed bites on spinos from carchies. The young would need to be wary but the smaller they get the more their prey as adults become the predators so.

[@rileyernst9086]

​@@victory8928 I would agree that bigger spinosaurus would certainly prey on younger carchies and the other way around when opportunity presents itself. I would also think that both species would probably not turn their snouts up at cannibalism either so the point is kinda moot. But I would also posit that like a giant ant eater a spino can defend itself against a similarly sized or larger carchie, but make no mistake, in this case it is spino defending itself. One of these species is evolved to hunt and kill other giant dinosaurs and it is not the spinosaurus. And sometimes, an animal just does not have time to do that, sometimes an ambush can take it so unaware that it's dying in the jaws of it's predator before it knows what is going on. If we indeed have evidence of carchies attempting predation on spinos, well, that is evidence of them doing just that, not all hunts end in a success and sometimes prey is dangerous. I mean we have irrefutable proof that allosaurus hunted, killed and ate stegs, and that sometimes they came away from the attempt with body piercings. Sometimes Trex killed and ate trikes, and we also have a trex femur that got horned by a trike. We do not have nearly as many spino remains as we have of trikes, stegs, allos and trexs, if we had more we would have a clearer picture. But my suspicion is that if you are designed to hunt, kill and eat 20m long sauropods, you are better suited to killing another predator your size than something that is eating 5m long armoured fish.

[@timexyemerald6290]

Nah. They already made unable to stand up. Can't even swim faster than Trex even though the massive tail. Spinosaurus is sunfish at this rate. 😅

[@theblackpearl3880]

It's just so hard to Study this dude He has just such a weird mix of Traits. No other known Lifeform in Earths History has that kind of Body Idea: he used his Hands to Anker himself to the Floor or dig in it depending on what he's trying to catch. He uses Sail and Feet to stabalize Roll when swimming. He uses Tail and Feet to probel forward. He uses Sail and Tail to stabelize Rotation.But Pitch might still be a Problem if Spino is still considered a floating Animal. We would need preserved Gastrolites to know these Guys did actully adopted this Behaivor. I think it's very likley because most living Animals are allready much smarter then the average Human gives it Credit for.

The way I see it Spinosaurus had to be able to swim. It could not fly and lived in a wetland environment. To not be able to swim well would put it at a competitive disadvantage to conventional therapods, to not be able to swim at all would make it ecologically improbable. The genre lived on at least 2 continents (East and West Africa)and in multiple wetland systems so it additionally needed to disperse to these areas and possibly maintain a genetic exchange. Secondly, it would likely have multiple foraging strategies targeting multiple prey items. I do not follow the heron line of thought, because that is silly, a stork is a much better analogue as storks are active hunters (they will wade along and look for fish and small animals in the water, and flush them out etc, herons sit and wait). So if Spinosaurus could float I would additionally propose a merganser like feeding ecology, ducking it's head into the water to catch fish and such. If spinosaurus could not float, it could bottom punt like a hippotomus. Although I suspect it is more likely that it floated at least as an adult.

[@EDGEscience]

No one ever stated it couldn't swim.

[@rileyernst9086]

@@EDGEscience That paper which found if it lost stability it probably floated neutrally on it's side with no hope of righting itself, or the model that had it floating upside down(can't remember what paper it was from) would be my primary example. It was probably more competent in the water than that, considering that conventional therapods did not seem to have this issue and floated perfectly well.

[@jahovah2979]

There is no doubt spinosaurus can swim. Current debate is if it was an underwater semi aquatic pursuit predator or if it was a wading shoreline generalist.

[@wolfsavage7647]

I wonder can the weight of the spinosaurus sink in the water just like a hippo in the tail of the spinosaurus just help it swim a little better but mostly they walk in underneath the water I wondered can that be a possibility?

Spinos rib-cage looks weird, if you take a look at it there is no rib bone to hold the organs or is very small. Other Therapods have a very big one from what I noticed, it makes me believe water helped it hold it’s organs like in fish. Please note this is just a wild uneducated guess…

[@leechild4655]

It must have dominated the shallows around the sea or where it could find easy prey like turtles lizards snakes birds, anything that gets too close, and if its too big it escapes to the shallows.

[@TheRealJosephCrane]

Just based off its physiology, spino's ecology was probably a mixture between an otter and a heron, but leaning more so on the heron side of things. Debate over, yw

[@EDGEscience]

A physiology that is not fully understood?

There’s a guy called frank fish in the paper of spino not being a swimmer. I have my doubts, he could be trying to spite the spino by discrediting it as a non swimmer. Or maybe their ancestors passed down the knowledge of spinosaurus not being a swimmer. Very hard to tell

[@keyboardwarrior3702]

What if they floated around like a giant Man-o-War? Big sail with low bone density to help float- and maybe catch wind? 😂 That tail looks like it'd be good at propelling along the surface. And the nostrils higher up so that most of its jaws can be submerged for hunting.

[@GaasubaMeskhenet]

pet theory is still that aquatic babies grow to lose the ability to swim

[@zerofreespeech3002]

Spino saurua was probably designed to fly spaceships

[@gregs619]

I say it was pretty damn aquatic. Walking around on land with those little legs, doesn’t seem very productive especially for a adolescent age spino who may need to defend itself it’s just too awkward 🤷🏾‍♂️ I can’t even imagine a fully grown spino standing it’s ground against even a mid sized theropod and I read there were carcharodontosaurus around... It would probably quickly slide back in the water instead of risking an injury because it was outmatched for sure even fully grown

[@floweryomi5351]

I think this video helped me better understand why there's a huge debate. I didn't realize that they were trying to prove that it was a semiaquatic *pursuit* predator. I do feel like the sail alone would cause too much drag for that kind of thing. I think it being an amphibious *ambush* predator would make way more sense - either in a predator way or in like a gharial way.

[@CJM-rg5rt]

I never understood why it's so debated. To me this thing is so obviously crocodilian in lifestyle/morphology.

[@EDGEscience]

Because science has more to it than just assumptions.

This is THE point of science! It functions similarly to a court room: Two (or more) sides to an argument nitpick eachother relentlessly until the winning side's proof is *infallable.* What the people arguing for spinosaurus not being able to swim are doing is forcing the people who claim it can to provide a water tight case. This is good science! And everyone's complaining about it! Lmao
