Was there a time in your childhood when you told your parents, ‘I want to study dinosaurs when I grow up!’? On National Fossil Day, we encourage you to channel that childhood curiosity. The event, a celebration of paleontology, often includes events at local museums, parks, and schools. Participants may get to see amazing remnants of the past, such as the dinosaur tracks on our homepage, which were photographed near Tuba City, Arizona, in the Navajo Nation.
