It's nearly impossible to accurately depict what life was like for young dinosaurs. But the Springfield Science Museum, using reconstructed nests, authentic dinosaur eggs–including an 18-inch egg laid by a giant, ostrich-like species of oviraptor–and an almost complete skeleton of a dinosaur embryo, presents an outline of what it was like for young hatchlings in those long-ago millennia.

Hatching the Past: The Great Dinosaur Egg Hunt also features hands-on exploration stations (where visitors can dig for eggs), cartoon-like illustrations of dinosaur family life (including the pictured "Sauropods Hatching," by Luis Rey), and photographs of dinosaur hunters and their discoveries.

Hatching the Past was created by Colorado-based Charlie and Florence Magovern, in association with the Harvard Museum of Natural History.
