is an dinosauromorph ichnogenus known from fossilized footprints found
in Poland and France. It may have been made by a dinosauromorph that was
a precursor to the dinosaurs, possibly closely related to Lagerpeton.
Fossils of Prorotodactylus date back to the early Olenekian stage of the
Early Triassic, making it the oldest known dinosauromorph. Its presence
during this time extends the range of the dinosaur stem lineage to the
start of the Early Triassic, soon after the Permian-Triassic extinction
event. Prorotodactylus is the only ichnogenus within the ichnofamily
Prorotodactylidae. Two ichnospecies are known, the type P. mirus and P.
lutevensis. Prorotodactylus mirus, the type ichnospecies, has been found
in the Holy Cross Mountains in Poland. It was named in 2000, with the
specific name meaning "strange" in Latin in reference to unusual
features in forefoot imprints.
