Dinehichnus

Dinehichnus is an ichnogenus found in the Morrison Formation that is attributed to dryosaurid dinosaurs. The trackways are present in Saltwash Member outcrops at Boundary Butte in southernmost Utah. "Dinehichnus" trackways are frequently found in groups, traveling parallel to one another. From this it can be inferred that the "Dinehichnus" trackmaker was a social animal. "Dinehichnus" tracks preserve impressions of three widely splayed toes on feet that point inwardly, as well as heel marks.
