Children are introduced to the excavation of reconstructed fossil sites, and to the identification and interpretation of the fossils discovered: trilobites or corals from the primary era, dinosaur bones or eggs from the secondary era, monkeys or fish from the Tertiary era, tropical forests 300 million years old… Which of these will they unearth? A fun way to talk about the paleo-environment, evolution and fossilization… Navigating through time becomes child’s play! Get out your shovels and brushes!
