Amblydactylus is an ichnogenus that has been attributed to dinosaurs. The generic name, derived from the Greek words amblys and dáktylos, means "dull finger". Two species of Amlydactylus have been named: A. gethingi, which references the Gething Formation where it was found; and A. kortmeyeri, which honours Carl kortmeyer who discovered the holotype.

Lower Triassic fossil footprint (ichnite) of the ichnogenus Chirotherium, probably caused by an early archosaur, and first discovered 1833 in Hildburghausen (Thuringia, Germany). This specimen, however, ist from the Helsby Sandstone of the Storeton Quarry near Liverpool. Its species name is Chirotherium storetonense.[1] © Ballista · CC BY-SA 3.0 · Wikimedia
