High Quality Content by WIKIPEDIA articles! This list of dinosaur ichnogenera is a comprehensive listing of all ichnogenera that have been attributed to dinosaurs, excluding class Aves (birds, both living and those known only from fossils) and purely vernacular terms. The list includes all commonly accepted ichnogenera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and ichnogenera that are no longer attributed to dinosaurs.
