Wakinyantanka (from Lakota Wakíŋyaŋ Tȟáŋka, "great thunderbird") is an ichnogenus of footprint produced by a large theropod dinosaur from the Late Cretaceous Hell Creek Formation of South Dakota. Wakinyantanka tracks are large with three long, slender toes with occasional impressions of a short hallux and narrow metatarsals.
The concept goes all the way back to the 1858 ichnological research of the Reverend Edward Hitchcock performed on the Newark Basin dinosaur tracks. Because underprints are produced indirectly they can only preserve the basic anatomy of the trackmaker's foot, whereas true tracks can preserve fine details skin impressions in favorable circumstances.
The East Berlin Formation is an Early Jurassic geological formation in New England, United States. Dinosaur footprints and trackways are abundant in this formation. These tracks include Eubrontes (belonging to medium-sized-theropods similar to Dilophosaurus), Anchisauripus (belonging to small theropods like Coelophysis), and Anomoepus (belonging to indeterminate small ornithischians).

Dinosaur Footprints in Holyoke, Massachusetts, USA is an 8-acre (3 ha) wilderness reservation purchased for the public in 1935 by The Trustees of Reservations. The Reservation is currently being managed with the assistance from the Massachusetts Department of Conservation and Recreation (DCR).
The tracks were originally created about 621 miles apart over a thin sandstone layer of silt and mud on the former supercontinent Gondwanan, which later separated and formed the south Atlantic Ocean.
Tyrannosauropus is a dubious ichnogenus of tridactyl dinosaur footprint from the Campanian of the Late Cretaceous of North America. Tyrannosauropus was named for a collection of footprints discovered on the ceiling of a cave in Utah which were suggested to have been made by Tyrannosaurus and informally labelled as "Tyrannosauripus" in 1924 (not to be confused with the separate, later ...
