Oxalaia

So when I was hanging out with DinoFights earlier, we were talking about ideas for fights and stuff. One of the combatants I proposed was Oxalaia. He fealt it was too close to Spinosaurus, and we dismissed the idea almost immediately. Since he left, I've been thinking about Oxalaia... It was quite a large theropod at roughly 46 feet, and it did look like Spinosaurus. But it lived on a different continent... Do you think that it was a synonym of Spinosaurus? If there was a land bridge between South America and Africa during the Cretacious, it could be. If not, then they probably split the common ancestors of the two when the land bridge disappeared... How do you think it behaved? Was it a strict piscivore? A more well rounded predator like Spinosaurus? Who do you think would win in a fight with Giganotosaurus?

I think Oxalaia was to Spinosaurus what Tarbosaurus was to T-Rex: Slightly smaller, very similar and a continent away

And Giganotosaurus would probably win. About the same size but bulkier and more of a hunter.

I agree with Spyrannosaurus. For one thing, I am one of the people who think Spino ate fish almost entirely. A few small dinosaur, less than 16 ft, and carrion here and there. I think Oxalaia would have been similar.

Yeah but Spino wasn't built like the rest of the Spinosaurids. It had more generalized jaws capable of subduing larger prey. A study from this year showed that diet was based more on individual size. Small to medium sized Spinosaurus would have fed primarily on fish, while full grown ones would be able to take larger prey. Also, according to research conducted on the isotopic compositions of turtles, crocodiles and other theropods like Allosaurus along with Spinosaurids, Siamosaurus was closer to the aquatic animals in isotopic composition than any other Spinosaur and Spinosaurus was the most adapted for land, as its crocodilian jaws suggest when compared to the gharial-like jaws of other Spinosaurs. Oxalaia had thinner jaws like Suchomimus, so it was probably closer to the piscivorous image of Spinosaurus everyone has than the actual Spinosaurus.
