Giant theropod, large sail, big bulky arms with giant claws, and is always debated about? Sounds like Spinosaurus right? WRONG! This is Oxalaia, the Spino's Brazilian Twin.

True, the original fossils were both destroyed. But because of the original spino fossils destroyed it intrigued people to go find a full skeleton. This is how researchers found out more about spino as their was a whole market where it's fossils were being sold and finally a almost complete fossil found in morroco.

Oxalaia could be a subspecies of spinosaurus due to the small evolutionary differences like the sale and more tightly packed teeth and a straighter snout <a href="#" class="seekto" data-time="231">3:51</a> my theory is that oxalaia and spinosaurus had a very close ancestor but split off very recently so one is more suited for a semi-aquatic/hippo life style and oxalaia is somewhat more of a land based spinosaurid with it’s more straightened snout or it hunted like spinosaurus and eating fish but that’s just my theory

<a href="#" class="seekto" data-time="148">2:28</a> I would argue that Carcharodontosaurus would’ve been the apex predator of Northern Africa rather than Spinosaurus but that’s just my opinion. Being longer and possibly heavier does not necessarily mean it would be the apex predator of its environment. For example Allosaurus is pretty universally considered to be the apex predator of the Morrison Formation despite being smaller than Saurophaganax and Torvosaurus (though to be fair Allosaurus is far more common than them). Diet likely plays a role in food web hierarchy because a Spinosaurus is clearly evolved to take on aquatic prey but probably would not be above taking on smaller terrestrial animals but certainly nothing as large as itself. Carcharodontosaurus on the other hand being a large Allosauroid likely feeds on anything it can get like ornithopods, smaller theropods, young sauropods, and even large old or sick sauropods through mobbing/pack hunting behavior similar to what is theorized for Mapusaurus

I imagine that due to its general body shape and weight distribution plus the nose location, it spent a ton of the time in water and probably ate a lot of fish. Due to the legs being awkwardly placed in relation to its body weight distribution, I can’t imagine it was doing a ton of land travel. That being said it could definitely get a decent speed if it needed to charge at something so I imagine it was like a much more adept alligator. Imagine an alligator that could actually be extremely adept on land! Terrifying

I remember like yesterday when they found him. I quickly ran to the museum to see the bones, I was 12 and I lived in the capital of that state (São Luís), not very long they made a event with many things, and one of them was him in full size (bones only), but of course it was based on the old Spino body (the JP3 body type). Now a sad fact: The museum where his bones were, was hardly a museum, the museum it's located in the "historical" part of the capital, and was pretty much a room with some fossils and some paintings (one of them was Oxalaia), I bet the living room of some of you is bigger than the museum. A fun fact: His name comes from a Deity from Africa, and alot of the culture of Maranhão shares from Africa.

Another use or benefit for the sail that I rarely see mentioned involves hunting fish. There are other ways to hunt fish then pursuit hunting and one such way is to use reach or bursts of speed to ambush prey and is used by both fish and crocodilians today. Reach can be accomplished by making a U-shape of the body towards one side. This will give a quick and long reach attack that can catch prey unawares of them being in danger. The sail would help with this tactic as it would act as a stop to prevent the center of the U to move in other direction too much. The main thing is that I can't imagine an animal group this successful and spread out with this many aquatic adaptations not being able to hunt in the water.

The Spino found in Brazil could have been named after Indigenous Americans of Brazil. Though I understand why, AfoBrazilians ARE Brazil's dominant culture. But its fine. With that said, Obatala is a sex/gender fluid Orisha, an Irunmole to be exact, a type of deity of the Yoruba people of west-Africa. Obatala along with Yemonja-a female Irunmole, are the duo that are responsible for creating the first human-bodies as commanded by the God of the Yoruba people Olodumare aka Olorun-who is sexless/genderless.

So looking at that creature, how does it not fall flat on its face when walking in the manner depicted in the video? I mean its body seems to have the same thickness from hip to chest. Its forelimbs appear to be almost the same size as its hindlimbs in thickness and density. Its tail does not appear to quite have the counter mass to balance it on its hips. And that head is enormous and must have been quite the weight on its own. By comparison with Tyrannosaurs where the forelimbs are significantly smaller and the chest tapers in from the hips this creature seems to be defying gravity and a centre of balance to achieve the posture depicted.
