What is "eubrontes"

Eubrontes (Hitchcock, 1845) is the name of fossilised dinosaur footprints dating from the Late Triassic and Early Jurassic. They have been identified from France, Poland, Slovakia, Italy, Spain, Sweden, Australia (Queensland) and the USA. It is a junior synonym of Grallator.

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 of Massachusetts in the early 19th century. They, among other footprints, were the first known dinosaur tracks to be discovered in North America, though they were initially thought to have been made by large birds.
