Big Tex,
It must be that all you guys from Texas are lacking in gray matter. So, pull your Ford F350 Diesel over at the nearest donut shop and wrap what purports to be a mind around the following.
You said:
: I am by no means a paleontologist
That's for sure.
:(what I know about dinosaurs is from my son),
at least you don't need to worry about Ivy League fees.
: but even if there were humans on the earth at that time, how could a group of humans armed only with spears and arrows defend themselves against Tyrannosaurus Rex, as well as Albertosaurus, Diplotomodon of Dromaeosaurus; all of these are similar to the T-Rex and all lived in the late Cretaceous Period.
Ever heard of digging a hole with pointy sticks inside it, pointing up, then disguising the aperture with a fragile covering of sticks and leaves etc....get the picture? Even a Texan would fall for that one. LOL.
Hope that helps.
