How it begins

At the back of the museum, behind the biggest skeleton, there is an old wooden door. A brass dial sits in the middle of it, like a clock with no hands. Dr. Okafor turns a big brass key. Clunk. "Would you like to see where the bones came from, your child's name?" she asks.

Click, click, click. Dr. Okafor turns the dial. "Three rules," she says. "Come back when the bell rings three times. Bring me one true thing. And never pick up an egg." Their Pet rushes past your child's name to the door. "Jurassic!" The dial stops. Cretaceous. "Nearly," smiles Dr. Okafor.

Your child's name steps through the door into warm sunshine. Seventy-seven million years ago, this place was a wide green valley. The air is warm and sticky. Somewhere, something honks like a big trumpet. "Remember the bell," calls Dr. Okafor from the museum.

A muddy path winds down the valley. In the mud there are footprints, each one bigger than a dinner plate, with three fat toes. "Something big walked here," says your child's name. Their Pet hops from one footprint to the next.

The hill is covered in nests, each as wide as a paddling pool. Big dinosaurs stand between them, humming softly. Then, wobble, wobble, roll! A speckled egg tumbles down the slope. It stops right by your child's name's boots. Whose egg is it?
