Eubrontes is the name of the footprints, identified by their shape, and not of the genus or genera that made them, which is as yet unknown. They are most famous for their discovery in the Connecticut River Valley, Massachusetts in 1802. They, among other footprints, were the first known dinosaur remains to be discovered in North America, though they were initially identified as large birds by Edward Hitchcock, a professor of Amherst College. Another major find occurred at Rocky Hill, Connecticut in 1966. Nearly 600 prints are preserved there in an area now designated Dinosaur State Park.
