yep. i can see this happening even with the weapons we have. dinos would get bigger and bigger to adapt to what we throw at them. if anyone saw the rex in the new turok you'll know what i mean. -- HA HA HA I'M ALIVE!
Yes, reptile like mammalians and such originated about the same time as dinosaurs, or even before. I would say before, but it's hard to tell how much of a mammal they really were since the most defining characteristics of mammals such as warm blood, hair or mammary glands are not fossilized.
