Rex vs Spino

I have been here (at Jurassic World) less than a day... I am not going to go through every single thread to see what you guys had to say. If you ask why I have over 50 posts, then I should tell you that most of those are from the Godzilla forum.

Spinosaurus had way more powerful and heavily-built jaws than people make them out to be. You see, its thin rostrum was actually quite dense and robust in the region posterior to the specialized cleft, especially compared to allosauroid jaws; they were actually quite robust despite being thin. This is an adaptation for resistance to stress exerted by the massive fish that made up a large part of its diet; spinosaurids needed to have very strong jaws to withstand such amazing amounts of pressure because they evolved to grip. Bite force is somewhat unknown (although some estimates point to 2-3 tons of force), but I can tell you now that spinosaurus did not have weak jaws the least bit in the realm of overall robusticity, even if its bite force was subtle.

@Spix Macaw Jack, you are misinformed. Spinosaurus teeth were hollow, conical (cone shaped), and unserrated, but they were most certainly NOT brittle and were in fact quite sturdy and heavily-structured. Spinosaurus\\\' jaws and teeth were designed for gripping powerful aquatic animals, so both needed to be very strong. The conical shape of spinosaurine teeth were perfectly-built for piercing and gripping, yet they were still thick and were more than capable of withstanding decent amounts of pressure.

Tyrannosaurus teeth were built like serrated spikes. This does not necessarily mean they were more resistant to lateral forces than the teeth of spinosaurus, as spinosaurus\' dentition itself was also very strong and thick and was designed to retain a firm grip on large aquatic animals without breaking. Tyrannosaurid teeth, on the other hand, were designed for crushing vertically and not gripping. The same goes for the jaws, which were very heavily-built and thick (both dorsally and laterally).

Man, the inaccuracies on this forum are insane...

Tyrannosaurus Bite Force- 3-9 tons psi

Spinosaurus Bite Force- 2-4 tons psi

Weight(the determining factor when it comes to size for animals) is heavily debated between scientists and everyday people.

And Godzillasaurus, it's not inaccuracies. It's a difference of opinions. Once you call someone flat out wrong, you lose nearly all credibility. End of story.

Sometimes when I see these Jurassic World noobs post these opinions without saying they're an opinion, and say others are wrong just pisses me off. I'm having trouble not stating what im thinking instead of being nice about it.

Oh well, I'm not an ass (it has nothing to do with the fact I'm Canadian), so I'll just nicely go out a shoot something tomorrow.

It's ok MrHappy, I'm with ya.

Ya know I go with the spinosaurus considering he is the biggest theropod and has a substaintial amount of speed, muscle, and claw (considering he can use his arms).....he might not have good bite strength but his endurance and speed could probably outlast a t-Rex...

The Jurassic Park 3 Rex was the kid from the previous movie. Tyrannosaurus and Spinosaurus are my favorite dinos after all.

First of all, i want to say that the bite force of Spinosaurus was anything but pathetic, it was miles away from the bite force of a T.Rex, but it was not something to mess around with, now to the task at hand, i would say that the T.Rex would win about 60-70% of the time

Im going with Trex do to its strength and bite force even with those tiny arms he was a dino to be feared of.

Tyrannosaurus Rex, for reasons already said. I have nothing against the spinosaurus, but I dont think he would win.

Spino, No Doubt !

Tyrannosaurus rex takes this 65-70% of the time for me. That thing was probably the most advanced predator ever. It had the greatest bite force of all time, one of the best senses of smell, binocular vision, and was intelligent to boot. Also, exactly a year since this was posted! Happy anniversary!

spino

large Carnivores rarely fight as it is a waste of time, energy and of course life... Carnivores cant afford to get hurt as even a small injury can lead to death by starvation. They usually front up to each other, have on round and the weaker backs off.

Anyhow, if they were to fight I'd have to say that if Rex got a bite hold on Spinos neck like in film 3.... Bye Bye Spino...

Looking back at this now..

I'm rather confused how this got stickied.

spinosaurus would win, t-rex due to current estimates weighs 5-7 tons, spinosaurus weighed 8-9 tons plus spinosaurs has experiance fighting other super predators (carcharodontosaurus) which is a dinosaur that is as big if not bigger than t-rex and spinosaurus has arms
