Carcharodontosaurus-Spinosaurus relationship

Not sure if they would hunt together. They may have ignored each other completely. They probably had different diets that way they could avoid conflict. Carchar probably fed on large dinosaurs while Spino hunted fish, small dinosaurs, and fed on carrion. Of course Carchar would have eaten carrion as well. If they did fight, Spino would have used it's claws to swat it's enemy while Carchar would have used it's teeth and the slash and dash method.

Dear Rex Fan, Why don't you ever acknowledge the fact that T-Rex ate carrion too and is thought by most respected scientists to be 40-43 feet? You never point out Rex's flaws... Sincerely, RexKiller

This is a discussion about the Carcharadontosaurus-Spinosaurus relationship. This has nothing to do with Rex. I do agree that he doesn't point out the weaknesses very often, but he his talking more how Rex could beat Spino. I think that Carchar and Spino would probably just ignore each other most of the time. If they did interact, Spino would probably just intimidate Carchar.

RexKiller, I did not mention Tyrannosaurus once in my comment. I have no idea why you started talking like I did.

I think he is just pointing out that you don't talk about Rex's weaknesses. It's just like how some people (you know who, that's right, FACT DUDE!) don't talk about Spino's disadvantages. Not sure about S-Rex, I think he might have some posts about the disadvantages, but I doubt it (not trying to sound rude, just saying). I personally like to keep everything even and talk advantages and disadvantages.

Maybe I don't, what I don't get is why he started going off on Tyrannosaurus. No one mentioned Rex until then, lol

@Rexfan, spinosaurus would have most definitely used its jaws in combat. In fact, more-so than its forearms. As I have explained before, spinosaurus had a very robustly-built jaw and tooth structure alike. That and the fact that its teeth were perfectly designed for puncturing deeply (they were, fundamentally, designed for gripping) implies that spine-related damage is a definite way that spinosaurus would kill an opponent. Carcharodontosaurus, on the other hand, was most likely restricted to quick killing techniques, as its very lightly-built jaw and tooth structure tells us that it would have killed with quick vertical downward strikes. Its jaws could be easily damaged in a head-on confrontation, unlike spinosaurus which was more well adapted for resisting lateral forces and gripping.

Oh yea, Makaveli7, carcharodontosaurus was horribly adapted, actually, for "manipulating" prey with its jaws. Allosaurs were not designed to do so, as their jaws and teeth alike were very vulnerable to lateral stress and were instead used quickly in forceful downward motions or backward pulling. Spinosaurus was much better adapted for this, as its jaws were more robustly-constructed and its teeth were designed for gripping and yet were still thick and spike-like in shape. Unlike carcharodontosaurus, spinosaurus' morphology heavily indicates strong reliance on gripping in predation, so there is not reason to believe that carcharodontosaurus had a more powerfully-built snout, because that is demonstrably wrong.

Godzillasaurus, nearly all the evidence for spinosaurs diet(powerful jaws or not) points to a diet of primarily fish. Sure, an animal as big as Spinosaurus probably can't survive entirely on fish, so it probably ate carrion and a number of smaller dinosaurs. And with claws over a foot long and backed by muscular arms, why wouldn't Spinosaurus use it's arms and claws in combat a lot? Carcharodontosaurus(and it's cousins overall) was a definite big game hunter. It's close relatives have left their bite marks on the bones of other large dinosaurs(Allosaurus bite marks on Camarasaurus bones for example), so I feel confident in saying that they had teeth and jaws that worked just fine when it came to taking on big game...

The fish that spinosaurus killed were actually pretty big and powerful.

Of course allosaurs were well designed for taking down large animals; that was they were adapted to do in the first place. But they were horribly adapted for gripping as evidenced by their lightly-constructed snouts and laterally-compressed dentition that possessed serrations best designed to be used with backward pulling. Allosaur bite marks may have been found on the bones of various herbivorous genera, but it was also poorly adapted for crushing bone. Spinosaurus, on the other hand, had a far more robust and heavily-constructed snout overall than those belonging to allosaurs that was far better designed for withstanding the pressures experienced by gripping.
