Um, it would smash everything up

yep. its the most fearsome predator for the dinosaurs at that time. velociraptor would be vicious too but their more vicious when their in groups of velociraptor. i feel bad that the dinosaurs extincted.. damn commet!!

veloceraptor will save us from the horrors of T-rex.

um theres no proff that it was a commet and the T rex is the only 1 thats been in a city b4 and wat mainland there r a hole bunch

T_REX RULES
but it is a good thing that they are all dead cause i dont want a T-REX to go in my backyard and eat my doggy:((
hehe lolz

just because trex destroyed the main land in the movie does not mean that raptors can`t. Raptors are in a pack and u can`t out run them. I think that raptor`s would be the worst in the book the people survied the rex only one person was killed by the baby but so much more were killed by raptor`s. i know that and i`m only 12 year`s old

but t-rex would also be bad if it made it to the main land oh and IZF to answer u`r Q. they mean costa rica i think cause that`s was where the bout in the book was going to so peace

I again agree with LOVE_dino....

This would totally destroy everything!

Like structural damage I say Rex, but physical human deaths I say Raptor. I agree with theraptorman.

The raptors because they´re too fast, they hunt in packs, they´re smarter and dangerous

Of course.

I agree with Vixie79. Raptors rule!

Raptor's hunt in packs, they ar enot solitary predators. And raptor's are small enough to maneaver undetected. It's pretty obvious when a t-rex goes on a rampage, people WILL flee!

Velociraptor=Cretaceous Einstien

I agree with Vixie79.

Structural damage: T-Rex
Being eaten and going through the digestive system of a dinosaur: Velociraptor

Velociraptors always hunt in packs, never alone. And they can open doors. So if there is more of them, more people get eaten.

The raptor will be more danger because it can hunt you indoors

Spinosaurus. The Spinosaurus will do the most damage. But I suppose next to the Spine, T-Rex will do most damage

As big and formidable as the T-Rex is. Based on the way the velociraptors are depicted here, they would be smarter and more agile given their compact size and work packs as well as opening doors.
