Tyrannosauripus is an ichnogenus of dinosaur footprint. It was discovered by geologist Charles "Chuck" Pillmore in 1983 and formally described by Martin Lockley and Adrian Hunt in 1994. [ 1 ] This fossil footprint from northern New Mexico is 96 cm long and given its Late Cretaceous age (about 66 million years old), it very likely belonged to ...
Wakinyantanka are large, tridactyl, and bipedal pes prints, with the middle (third) toe being the longest (mesaxonic), typical of theropod footprints. The digits of Wakinyantanka are long and slender, and are widely divaricating so that the prints are roughly as wide as they are long, averaging between 55–60 centimetres (22–24 in) long and 60 centimetres (24 in) wide.
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.
