Re: new dinosaurs and 16 Foot Man Eating Croc Caught In Uganda
I'd expect the more advanced types
to supplant the basal ones, just like in the west.
Why do you think they had the same niche? *Dryptosaurus* retained an
extra-large thumb claw. It clearly did something that tyrannosaurids didn't
That's why "advanced" tends to be a thinking mistake.
