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 more than 260 footprints researchers studied were found impressed into mud and silt along ancient rivers and lakes, with more than 3,700 miles separating the ones in South America and Africa ...
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.
Researchers found that the dinosaur footprints were discovered over 3,700 miles away from each other – and that the footprints were made 120 million years ago on a "supercontinent known as ...
The Connecticut River Valley trackways are the fossilised footprints of a number of Early Jurassic dinosaurs or other archosauromorphs from the sandstone beds of Massachusetts and Connecticut. The finding has the distinction of being among the first known discoveries of dinosaur remains in North America.
Nearly 200 Jurassic footprints found in southern England reveal new insights into 166 million-year-old prehistoric creatures, according to scientists.
The footprints were first discovered in the 1960s by station manager, Glen Seymour, in the nearby Seymour Quarry. Palaeontologists from the Queensland Museum, including Mary Wade and Tony Thulborn and the University of Queensland excavated Lark Quarry during 1976–77 (the quarry was named after Malcolm Lark, a volunteer who removed a lot of the overlying rock.)
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.
