Did you know that you have a little bit of dinosaur in you?

And it’s your cousin’s fault. She dared you to pitch a peanut high in the air and catch it in your mouth. You didn’t know it had a nitrogen atom that used to be in the egg of a Hadrosaurus.

This humorous story follows a nitrogen atom as it journeys from dry bones to your skull – and beyond!

The journey began with Book 1, A Little Bit of Dinosaur, which received a starred Kirkus review. It continued in Book 2, A Little Bit of THIS Dinosaur. In this new story, the amazing circle of life—or the conservation of mass—is again illustrated through a historical look at the Hadrosaurus dinosaur.

Sisters Elleen Hutcheson and Darcy Pattison team up again for a new adventure with the circle of life. Each still wonders why their mother taught them to throw food and catch it in their mouths.
