Your imagination has replaced any shred of reality for you.
Animals we have remaining today are far more hazardous than TRex could have been. Just his limited thoractic capacity made it impossible to move very fast or far.
An african lion, a tiger, an alligator, or a cape buffaloe are far more dangerous.
Lots of claims....baseless ones, but I’m not surprised.....lions can be disuaded with a few simple spears and a group of people yelling....or even fire....but of course, you know that with your uber-intelligence. A 40+ foot long T. rex would figuratively laugh at the notion of a human warding it off. Think Trex couldn’t outrun a human? Care to make super-intelligent statements about the OTHER meat eaters that Man walked hand in hand with to the vegetable garden? I’m sure you have a super intelligent itemized list as to how Man survived amongst the possible man-eaters:
Abelisaurus
Achillobator
Afrovenator
Albertosaurus
Alectrosaurus
Alioramus
Allosaurus
Anserimimus
Appalachiosaurus
Carcharodontosaurus
Carnotaurus
Ceratosaurus
Cryolophosaurus
Daspletosaurus
Deinonychus
Dilong
Dilophosaurus
Eotyrannus
Eustreptospondylus
Fukuiraptor
Gasosaurus
Giganotosaurus
Well......I made it into the G’s before getting bored....DO TELL of all that imagination that is needed to escape all the large meat eaters that Man had to deal with in Absurdistan.
