T. rex Time Warp

A T. rex chased a stegosaur until the latter said,
“Excuse me: By the time that you exist, I should be dead.
My era’s late Jurassic, whereas yours is late Cretaceous.
By eighty million years, I must predate you; that’s veracious.”

Now, T. rex brains are larger than traditionally thought,
But this one got confused and thus responded, “I think not.
You herbivores do not engage in larger-game predation.
You might just be voracious, but you’d better know your station.”

The stegosaurus rolled her eyes and patiently replied,
“Well, let me put it this way: Our temporal gap is wide.
Your period is closer to the Information Age
Of humans than to mine, so would you kindly disengage?”

A moment passed, and then the T. rex said, “I see your point.
Apologies; I don’t know how I got so out of joint.”
With that, the hunter turned around and ran the other way
To chase and munch on humans from the modern present day.
