| Ichnogenus: | †Archaeornithipus Fuentes Vidarte, 1996 |
Archaeornithipus was a genus of large bird ichnogenus discovered in Spain. The tracks date back to the Berriasian stage of the Cretaceous, making them among the oldest bird trace fossils in the world.[1] However, a 2026 study found the type ichnospecies, based on penetrative tracks to be a nomem dubium.[2]
