Early Dinosaur History in the United States

What was the first dinosaur track to be described?

The first dinosaur track to be described anywhere was a three-toed track from the east bank of the Connecticut River near Holyoke, Massachusetts. This large footprint cast was originally named Orinithichnites giganteus, but was later renamed Eubrontes giganteus. A lithograph of this track was incorporated into William Buckland’s Bridgewater Treatise in 1836.
