Theropod ichnites (aka fossilised footprints) at Dinosaur State Park, Connecticut, USA. These prints are known as Eubrontes (=Grallator) which date from the Early Jurassic.
Eubrontes is not the name of a specific dinosaur, but is the name of the footprints themselves (a type of ichnotaxon or ichnogenus) which basically categorises the shapes of these trackways and the dates of when these prints were made. We do not know exactly what dinosaur species created these footprints.
