It began with an egg!
What size was the egg?
The egg was as big as your head . . . maybe.
Don't you know? Why don't you know?
It was millions and millions of years ago!

A grandson and granddad are touring the special T. rex exhibit, and there are so many things the young boy must know. Was the dinosaur egg in a nest? How did this T. rex grow? Did he track down live prey? The boy is intrigued to learn that as much as we know for sure about the greatest meat-eating dinosaur of them all, there is even more left for us to find out. Could the boy himself someday make those discoveries?
Back matter includes an index and a note about T. rex.
