Dinosaur State Park and Arboretum is a state-owned natural history preserve occupying 80 acres (32 ha) in the town of Rocky Hill, Connecticut.

[3] The Rocky Hill dinosaur tracks were uncovered in 1966, adding to the extensive legacy of fossil discoveries made in the Connecticut Valley since the 19th century.

The sandstone layer preserving the tracks is a section of the East Berlin Formation, which corresponds to a sandy lakeshore from the Early Jurassic, over 200 million years ago.

[6][2]In addition to the tracks, the dome houses life-sized dioramas of plants and creatures, including Dilophosaurus, from depict the Triassic and Jurassic periods.

[4] The arboretum's 2 miles (3.2 km) of trails pass through some 250 species and cultivars of conifers, plus collections of arborvitae, chamaecyparis, ginkgo, juniper, katsura, pine, sequoia, and magnolia.
