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

And it's your mother's fault. She fed you that cheese sandwich, which had a calcium atom that used to be in the bones of a T. rex.

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

This story is inspired by the classic environmental book, A Sand County Almanac, by Aldo Leopoldo, which beautifully discusses how man and nature are interconnected. This amazing circle of life—or the conservation of mass—is illustrated in this story with humor and a touch of empathy.

Sisters Elleen Hutcheson and Darcy Pattison team up to bring Leopoldo's circle of life to kids. Each is shaking her finger at their mother wondering why she fed them that cheese sandwich.
