Dinosaur State Park and Arboretum

Dinosaur State Park and Arboretum in Rocky Hill, Connecticut, is an 80-acre preserve that protects one of North America’s largest dinosaur track sites, with fossil trackways left in sandstone about 200 million years ago at the start of the Jurassic period. Discovered in 1966 during excavation for a state office building, the site was quickly protected and opened as a park in 1968. A geodesic dome shelters about 500 tracks, while many more remain buried. The park also interprets the East Berlin Formation, notable Eubrontes footprints, and other Connecticut Valley fossils, while its arboretum features plant collections emphasizing families associated with the Mesozoic era.
