OK.This is basically about whats your favorite dinosaur(s)and why you like them.For me I am fond of the Velociraptor.I like how its small but ferocious.
Anyway, I don't care for dinosaurs so much. However, I do have a fear of one specific dinosaur. The Utahraptor. *shudders* This thing is Freddy Krueger on crack.
PS:The Allosoarus (forgive me if I misspelled that) is the biggest dinosaur,not the T-rex
T-Rex was bigger than the Allosaurus, but not as big as the Spinosaurus within the theropods. If you want biggest, you're going to have to look at sauropods.
My favorite would have to be Gastonia. I just think Gastonia looks awesome with all those spikes. Plus, I think it's the first Ankylosaur mentioned in this thread.
