I'm sure most of you now saw the trailer for Jurassic World. In the trailer, they explained that the new D-Rex was going to be a genetically modified hybrid. But the question I'm sure some of you are wondering is: What will it be a hybrid of? Obviously just by the name alone, T-Rex is going to be in the genome somwhere. But, what else? A lot of people think it's a hybrid of Tyrannosaurus Rex and Velociraptor. That could be the case. Maybe it could be a hybrid of T-Rex and Carnotaurus.

What do you guys think? What dinosaurs do you think they used to make D-Rex?
