A LITTLE BIT OF DINOSAUR!

An atom of calcium makes the journey from dinosaur bone to child’s body in this entertaining tale about the conservation of mass.

When the narrator announces to a brown-haired, blue-eyed child: “You have a little bit of Tyrannosaurus rex in your jawbone,” the child looks astonished. It is, the narrator explains, the child’s mother’s fault. But how did the bit of dinosaur get there? The narrator guides the child—and the reader—through the saga of a dinosaur’s living, dying, and being buried long ago. As rain erodes both the rock burying the dinosaur and a little bit of the dinosaur’s toe bone, calcium from the bones washes into the river. From there, the water irrigates a corn field, the corn is fed to a cow, and the cow makes milk, which becomes cheese, which the child’s mother purchases for lunch. The calcium becomes part of the child’s bones—and will one day again return to the cycle to perhaps become calcium in the spine of a blue whale. Hutcheson and Pattison introduce difficult science concepts in simple, accessible language. Although death is a part of this cycle, it’s handled in a scientific and not scary way. Joven’s comical, retro, and ingenious illustrations—featuring bright colors as well as a cow that rides inside a tractor and has a milk faucet inside her body—are brimming with kid appeal.

A science-centric winner, especially for young dinosaur lovers.
