could a new breed of dinosaur wipe out all of the other dinos?

One breed? Highly unlikely. If it was sauropod killing large, Dromeasaurs and similar size wouldn't be worth it's time, and it would competition from other dinosaurs of its size.

Maybe a pack of T-rex with the intelligence of a Troodon! So, as MrHappy said, very unlikely.

Haha, it was only an impossible thinking... and Zillas (not GODzillas), are iguanas, as long as I'm aware of.

I understood that, haha. ;)

This situation would be highly, HIGHLY, unlikely. So many fans were ticked off when they killed off T-rex. I'd hate to see how many would flip out if they killed off the other ones.

No... On the island, there was 12 or 15 spicies, one nublar there was 20 to 30 ish (rough estimates people) Adding one from site B might add some impact to the ecosystem but not much... 

also, it caused so much trouble when they first made the dinosaurs, why would they do it again... but with intention...?

15 species on Nublar according to the book if I'm right.

NO its ALL of them made in to one dino (obviosley!)

HELLO BREED = GET BORN,GROW UP,MATE,GIVE BIRTH CYCLE OF LIFE!!!!!!!!!!>:(
