When a dinosaur hatches from the egg that Little Grunt brought home for dinner, Mama and Papa Grunt let him keep it as a pet until it grows too big for their cave.

When Cave Boy wants a pet, he tries a woolly mammoth, a saber-toothed tiger, and a dodo bird, but none seems suitable.

Thousands and thousands of years ago, a young boy gets his first hunting bow and learns to shoot, but he prefers to use the bow to make music.

Thirty thousand years ago, an imaginative child sees the shapes of animals in clouds and on the walls of the cave he shares with his family, but no one else can see them until he makes the world's first drawing. Includes author's note on cave drawings.
