Grallator (GRA-lÉ™-tor) is an ichnogenus (form taxon based on footprints) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs. Grallator-type footprints have been found in formations dating from the Early Triassic through to the early Cretaceous periods.
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 ...
Footprints dating back 120 million years show where dinosaurs were able to cross between land that's now part of two different continents. Matching dinosaur footprints found more than 3,700 miles ...
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.
Footprints left by three-toed theropods. The study found that the majority of the fossil footprints were formed by theropod dinosaurs, which were characterized by their three toes and hollow bones.
In the United States, dinosaur footprints and trackways are found in the Glen Rose Formation, the most famous of these being the Paluxy River site in Dinosaur Valley State Park. These were the first sauropoda footprints scientifically documented, and were designated a US National Natural Landmark in 1969. Some are as large as about 3 feet across.
