Who do you think is the deadliest JP predator?

I do agree with you on the basis of T.rex being the most powerful, or one of the most powerful, JP predators.  And I only say that because JP3's Spinosaurus was also depicted to be immensely powerful and basically indestructible.

My only argument is that the Velociraptor species were shown to be the most intelligent dinosaurs on both islands.  They worked together in cohesive units, communicated at a level previously un-thought of among dinosaurs, and had the ability to run faster and jump higher than any other creature in the films.  Then again, an adult T.rex and Spinosaurus probably couldn't jump anyway due to their weight.  And those two previous genera did not work as well together among their own kind as well as the raptors, and their communication was not as complex as the raptors.

In that regard, JP Velociraptors were the most deadly predators.  

A contrary argument would be that while the raptors were most dangerous in packs, one individual was not as great a threat while one T.rex alone could cause more damage and chaos.

I am truly torn about this issue, but I wouldn't want to meet anyone of them face to face.

Spinosaurus

In my mind it would be a tie between Rexy, Spino, Raptor, and Troodon. Although I would have to lean towards Spino, but the rest are still high ranking.

so far
I think the troodon are the deadliest predator in jurassic park

sure they're not as big and as strong as the rex

but their small size allows them to run through small holes to ambush their prey, intelligent and pack hunting habit like a raptor, and to make it even worse, they are venomous is the reason why the troodon are the perfect killing machine in JP

Spinosaurus. ;)

I hope they put an acrocanthosaurus in the Jurassic World, that would be awesome. :)

I say the Velociraptors, followed by Rex. If the JP3 Spino was any form of realistic, it wouldn't have survived that movie.

I'm leaning towards the Carnotaurus here. It might not be as powerful or as smart as the Raptors and the T.rex, but being able to camouflage itself makes it the most dangerous imo.

Velociraptor. While T. rex and Spino where two immensely powerful predators, they where, come in and kill one or two. Velociraptor. They committed Homicide. Maybe even genocide. They are as smart as the troodon, and bigger as well. (plus, Troodon was never officialy in JP)

"Velociraptor" (it's actualy a Utahraptor). It's smallish, but stealthy. While Rex and Spino are large, bulky behemoths, raptors have stealth and advanced intellignece.

Carnotaurus if they use their camo they could kill anything.

I don't know, that Soino was pretty stealthy in JP3.

Sci-Fi king, the "Velociraptor" was actually Deinonychus. Utahraptor was taller than a man, and much longer there the raptors there. Grant said 9 feet long, Utahraptor is something like 24 feet.

People are forgetting that, though they are intelligent and stealthy/quick, people have a chance of surviving a Raptor attack/bite. They don't have that luxury with Tyrannosaurus, and even Spinosaurus. I consider a Raptor pack to be nearly (if not as) deadly as an adult T. rex, and the Spinosaurus to be second. 

Agreed. Gennaro was killed in a matter of seconds by Rexy. Muldoon struggled nearly three times as long, but that's only because the thing got him from the side and surprised him. 

Exactly. Rexy slaughtered Gennaro, while I believe Muldoon stilll didn't really have a chance of at least escaping the initial attack, he could've escaped and struggled for a long time. T. rex is deadlier than one raptor, and possibly more than a pack. One attack, and the persons done for. ;)

I'll agree that one Rex or Spino is deadlier than one raptor. Most things are. One raptor, a JP Velociraptor does not make. The raptors are known for thier ability to open doors and sneak attack. Stealtheartand brains, its what wins wars.

A little firepower helps as well General. A pack of Raptors would be nearly unstoppable. A Tyrannosaurus Rex would be nearly unstoppable. A pair of Tyarnnosaurus Rex would be even more nearly unstoppable. A pack of Raptors and a pair of Tyrannosaurus working togather against a common enemy would be the most unstoppable thing this world has ever seen. Even King Leonidas and his Spartan army would have second thoughts about fighting them.

I gotta go with Troodon.

Thanks ^ to all!

@Mr. Happy, Definitely. Velociraptor pack is nearly (if not as) deadly as a T. rex. I'm pretty sure any army would think twice before taking on a T. rex and raptor pack. 

@Something Real- Agreed. As deadly as a large pack of raptors if not more, at 45-55 ft in length, sheer muscle, immensely unbelieveably powerful jaws, and an intelligent killer-instinct based brain. T. rex was unstoppable.

@TheMoreYouKnow, Thanks for the post, I don't agree, but I respect your opinion.
