The T-Rex

The T-Rex gives a mighty roar:
"I'm the most famous dinosaur!"

But just there watching all the while,
Is the smiling crocodile.

Who says with glee and snapping jaws,
"But my descendants will outlive yours..."

The T-Rex says "It can't be true,
I'm far bigger and better than you."

But croc says "No I'll still be around,
When you're just bones stuck in the ground."
