Carnotaurus vs. Spinosaurus

[Giral2010]

Wanna hear the most hilarious thing of all? A real Carnotaurus wouldn't even attempt to attack a real Spinosaurus. And not for the reasons you might think either. A real carno was half a spino's length (literally) and 1/3 of it's weight at the most. The Spinosaurus would simply be too big to attack. Also, it would likely be wading or swimming around looking for its dietary staple: fish. It's incredible how off the mark both films were when it came to their starring dinos.

actually, many paleontologists say that the one skeleton found had a "premature" structure and might have grown from 30-50 feet long.

I've never heard that theory.... But okay then!

Wait, are you referring to Spino or Carno?

[RedZillaKing]

Spinosaurus has a maximum length estimate of 18 meters (59.4 feet). That's friggin' sauropod sized.

[Rody]

Okay, I couldn't tell from Giral2010's post.

Actually, Spino lived alongside a close relative of the Carno - Rugops. As far as I know, it was about the same size as Carnotaurus.

[RedZillaKing]

And it probably didn't attack adult spinosaurs. Likewise, I doubt Rugops had to fear predation from Spino either. I wonder if Spino's sheer bulk restricted it to its semi aquatic lifestyle... It is theorized in upper estimates to be 13-18 tons!!!

I don't quite believe that one. Something about it just seems off.

Rugops wasn't a giant predator, unlike Spinosaurus and Carcharodontosaurus (which may have been the apex predator of the time) Carnotaurus wasn't likely to be at the top of the food chain either.

Spinosaurus might have, but not because it was heavy. A similar theory was thought about large sauropods having aquatic styles, but that was (I think) proven wrong. Spinosaurus probably did as that was where it's source of food was.

[RedZillaKing]

The sauropods being land dwellers makes a lot more sense to me, though. Spinosaurus was a biped. The thought of such an ungainly creature chasing down prey is just absurd. Especially at around twice a tyrannosaur's weight. The idea of a Spino thigh deep in the water makes more sense. Hell, studies of its bones even suggest that it was semi aquatic. I wouldn't be surprised of Carcharos munched on spinos occasionally either.

Predators don't normally eat other predators

[RedZillaKing]

Actually, with cannibalism apparent in several species of predatory dinosaurs it's not too far fetched.

[Rody]

In the modern day, it is fairly common for large birds of prey (e.g. great horned owls, golden eagles) to attack, kill, and sometimes eat smaller raptors.

Since birds are considered dinosaurs' closest living relatives....

Not true. Some species of anacondas (which is a predator) prey on caimans (also predators). It all depends on where they are at on the food chain. Also, you never know about Carcharodontosaurus preying on Spinosaurus. If I'm correct, Spinos are larger than Carcharodontosaurus, which gives them the size advantage. If the Carcharodontosaurus was hunting in packs, like other species of Allosaurs, it could easily take on a Spino.

Just because they are their closest living relatives would mean that they would act the same. They may be structured similarly, but dinosaurs (during the Jurassic and Cretaceous) were the dominant species, while birds of today live in a worlded ruled by mammals.

Wow, this thread went into a discussion on dinosaurs and predator behavior.

[Kaiju-King42]

Well it does involve a fight between two predatory dinosaurs, so I'm not surprised.

[RedZillaKing]

The Spinosaurus was MUCH larger than a Carcharo. That doesn't change the fact that the Carcharo was way more lethal.

One might compare the two to a crane & a golden eagle. The crane is the larger bird, but the eagle is designed to kill larger prey - which may include the crane.

Well, that's true, but do you see the golden eagle hunting creatures as large or even larger than itself? No. Once again, it can be useful to compare extinct predators to living predators, but Carcharodontosaurus may have hunted animals that could be even bigger than it. Golden Eagles however hunt smaller animals, such as smaller birds, ammals, and reptiles. It isn't a fair comparison.

Except the Spinosaurus is nearly, if not just as powerful a creature as a Carcharo, in addition to its superior bulk and size, so the crane vs eagle argument doesn't really fit. I don't doubt that a Carcharo would beat a Spino more times than vice-versa, but I don't see shark-tooth risking such a confrontation unless it was in a pack.

[HikizuruBeat]

I think a Carno might win. Isn't the Spinosaurus main diet fish anyways.

I really meant a juvenile, teenaged or sick Spino. Most predators won't even attack a large healthy adult animal. Especially large healthy adult animals twice their size!
