Basically, every single group of amniote animal has adapted to aquatic habits. You've got your waders - the ones that aren’t adapted for going in the water but still nab some munchies from the sidelines. These are the critters that don’t like to get wet. Then you have your sub-aqueous foragers - the critters that like to get wet but aren’t hardcore deep divers. They love to suck up soft-bodied water beasts or scrape slimy algal plants off rocks. Lastly you have your deep-divers. These are the critters that aren’t quite as hardcore as fully aquatic animals but love to go touch the bottom of the pool and snack on anything that moves. These types of aquatic ecologies have popped up independently dozens of times throughout the evolutionary history of life on earth.

I am really happy we actually ended up with a giant stork dinosaur. I think if we look at the paleo enviroment, baryonyx inhabited a land of large sprawling but seasonally dry water courses. It makes complete sense to me that whilst it was pursuing prey underwater it could and did move between water holes. Spiney lived in two massive estuaries so it probably never had that issue and suchomimus was carving out a 'giant stork' niche alongside sarcosuchus imperator, whom was the aquatic super predator of its faster flowing riverine home(i really dislike the heron analogy as herons hunt very differently to storks, utilising stealth and a precise strike with their fishing spear tongue and storks hunt much more like how it has been proposed for spinosaurids, probing with the beak half submerged and driving fish forwards into the beak with the feet)

This definitely makes much more sense now that Spinosaurus is more of an underwater walker than an agile swimmer. Even though this new study shows more insight on the probability of Spinosaurus having a more aquatic lifestyle, I still need to give credit to the 2021 study that pretty much explains that Spinosaurus may have been very inefficient at swimming lol. THAT'S why a freely swimming, underwater pursuit predator Spinosaurus made very little sense to me, but a bottom-walking ambush predator Spinosaurus makes much more sense. I don't really think the lifestyle of wading is completely out of question because one still does what works and that doesn't really exclude wading OR subaqueous foraging. Perhaps Spinosaurus and Baryonyx could perform both, with either species adapted more or less to one or the other.

That quote from Navallon sort of alludes to this, but if I remember right the Holtz and Hone study was specifically looking at evidence for aquatic pursuit predation in Spinosaurus, and the new study considers subaqueous feeding more generally.

@decimation9780 2 года назад

I was always under the impression that Spinosaurus was partial to walking along shallow rivers, both foraging for food as well as avoiding other large theropods in order to avoid any unnecessary fights. Granted we have little in terms of an actual skeleton, however from what we have found, it lends more credence to a semi aquatic lifestyle like that of Crocodilians, while still having the ability to function well on land like other large theropods.

My impression is probably more accurate than several of the concepts that have been drawn up using the known facts of Spinosaurus.

We only need to look at the Spino’s skull. Its skull is taperered, narrow, and aerodynamic. Ideal for catch small, lightweight prey like fish. The sail-like spine likely helped balance him while his most likely webbed feet need led him to navigate the surface of water with his head below the surface. Or maybe he was a great swimmer. Either way, his jaw was not wide enough to apply any significant amount of bite force compared to something like T-Rex whose jaw was wide and attached to a thick wide neck. Being partially aquatic would mean spino wasn’t a great runner and likely didn’t like to catch large land prey. Instead he would have waited near water for small prey to come to him, or he would go swimming.

@alifeoncechris Год назад

Interestingly enough study’s show they had very very similar prey to other large theropods and not similar to full aquatic fish eater. I suggest watching the David hone lecture on them. It’s extremely interesting and informative.

@picksalot1 2 года назад

Good informative video. 👍 Perhaps Spinosaurus were drift hunters, using their sail something like the Portuguese Man o' War. If they had camouflaged skin, they'd look like a big log or debris just drifting in the water. Fish love hiding under such objects away from the shore, and seemingly "safe" from predators. The sail could also provide additional "shade," something that fish like to hide in to ambush prey. This makes fish easier to see to catch by "surface" predators, as the "Black Heron" demonstrates and takes advantage of.

Wouldn't it be possible, that Baryonyx was on the way to evolve back into a wading/land-based lifestyle, hence it looking like a mix of both worlds. Evolution isn't just a one-way street after all.

@@Deform-2024 Which paper is this and by whom? I tried looking and nothing is circulating the news section on Google about the 10 metric tonnes Tyrannosaurus. Scotty, as far as publication goes, is 8870kg and that's already debated by other paleontologists like John R Hutchinson whom said the size/mass difference between Sue and Scotty were very little. To quote Pete Makovicky "Scotty's femur has a smaller measured circumference than Sue (1.7 percent), but is slightly longer (1 percent), the tibiae are an exact tie, and Sue's fibula is longer (3 percent). Scotty’s hipbone is reported as just under 1% longer than Sue’s. The differences are tiny, comparable to what you would find in comparing the right- and left-side bones within one animal, and therefore, speaking as a scientist the two specimens are statistically indistinguishable in size and thus tied for largest T. rex.” It's also important to remember Scotty is 65% complete while Sue is 90% complete.

It is highly likely that couples of Spinosauri would lay on their sides and interlock their limbs, forming a singular unit, and could achieve shared airborne flight by oscillating their dorsal fins in unison, leading to the ability to fly at altitude over bodies of water and seek out prey items from the air as a team.

I'm willing to bet that the next paper on spinosaurus will prove it to be terrestrial. And then the next aquatic. And then terrestrial...

@paleozoic 2 года назад

Honestly, it probably will go back and forth. Isotope data of teeth show that it did hunt on land as well, and some anatomical aspects like the placement of the nostrils pointed out by Dr. Hone are still unanswered issues. That said, while unlikely, there could possibly be an undescribed late surviving Baryonychine comparable to Suchomimus that may be skewing the data on teeth isotopes.

@diegonatan6301 2 года назад

Maybe Spinosaurus way of life was something more akin to a polar bear of the tropics. A polar bear is a good swimmer, but not like a seal, it will eat anything that it can get, be it a fish, a penguin, a seal or even a reindeer. Also the nostrils of a Spinosaurus is very much positioned like the nostrils of a penguin, so it doesn't need to feed like a heron.

Another possibility for the lack of many aquatic Dinosaurs may be the non Dinosaur sea monsters that filled those niches and maybe even fed on Dinosaurs from time to time.

I'll have to find the link for it again but there's this great documentary done by a famous paleontologist where he disputes some of the claims that spinosaurus was a mostly aquatic dino based on some inconsistencies in previous analysis', a closer look at the body structure/comparison to modern animals, and a bit of a closer look at the diet of several spino specimens where some showed some to a decent amount of predation on fish and other specimens showed very little to no predation on fish but rather more on smaller dinos

@davidbeddoe6670 2 года назад

Always thought its proportions oddly long, like Michael Phelps animorphing into a dimetrodon with a gharial's head and a gannet's torso. The spine must have been for either regulating bodyheat in deeper water then, or holding breath as well. Or they might have been able to propel themselves with it as an extension of the tail for explosive speed, perhaps also to pin their feet to the bottom while attacking, for leverage.

@brettwood1351 2 года назад

With how many large predators it shared it's environment with, I wonder if it helped make it looke even larger and more frightening as well.

@ScionStorm1 2 года назад

100/10 for that Phelps description. That's now stuck in my head.

@MustardSkaven Год назад

The 2022 study "Spinosaurus is not an aquatic dinosaur" actually says the sail is a hindrance for swimming, not an asset. According to the max speed estimates, a Spino would not be able to catch up to Phelps.

@davidbeddoe6670 Год назад

@@MustardSkaven I doubt they bothered diving much, except as juveniles escaping predation; they probably had no sail when little. Also, no human swimmer is outpacing a 40' reptile with a huge oar for a tail, I don't care how long his torso is.

Since most, if not all the sail-backed animals seem to be aquatic/semiaquatic, maybe we should think creatively about what they were used for in the water. It would be weird if they literally used them as sails. Maybe it only makes sense for the gigantic shallow seas we don't have in our time.

@temmy9 2 года назад

@paleozoic 2 года назад

The sail or paddle tail do not appear particularly adapted for swimming, and more likely for signaling or display. Not that a Spinosaurus would even need to swim that efficiently considering it's prey are things like Ceratodus (lungfish), gar, bichir, Mawsonia/Axelrodichthys. Isotopes of teeth also show that it was hunting on land, though you could argue they might belong to a different contemporary spinosaurid.

@UniDocs_Mahapushpa_Cyavana 2 года назад

@@paleozoic Sailing is not swimming. Sailing is also done for longer distances. Also, land animals go into the water a lot. That's why wildebeest are hunted by crocodiles. The spinosauruses could be taking advantage of a migration route.
