Jedi, I’m sorry to correct you, but I HATE seeing incorrect Dino facts, so here goes...

T. Rex itself did not start out a 3 feet tall. T. Rex’s ANCESTORS did. There were many different species in the tyrannosaur evolutionary line that led up to T.Rex at the very end of the mesozoic. Allosaurus and Giganotosaurus are not related to T. Rex, they belong to entirely different groups of theropods, and those two names are NOT different names for T. Rex.

I’m sorry
