Discovered in 1966 and opened to the public two years later, Dinosaur State Park is one of the largest dinosaur track sites in North America. The park offers both indoor and outdoor experiences year round. A geodesic dome covers the museum area where early Jurassic fossil tracks made 200 million years ago are on display. Just outside the museum are more than two miles of nature trails and the Dinosaur State Park Arboretum, which contains more than 250 species of plant families that appeared during the dinosaur age. The museum also displays a bird’s-eye view of the preserved Mesozoic floodplain. Dinosaur tracks, dioramas of Triassic and Jurassic environments, fossil collections and interactive exhibits can all be found here. The Friends of Dinosaur Park and Arboretum (FDPA), established in 1976 and governed by a board of directors, operates as a nonprofit organization devoted to promoting a better knowledge of the area's natural history. The FDPA also funds educational programs at the park and is always looking for volunteers. Dinosaur State Park is also part of the Bureau of Outdoor Recreation, Connecticut Department of Environmental Protection. Pets are allowed in the picnic area of the park, but not on the trails or in the museum.
