These footprints have been found in Callovian/Oxfordian eolian sandstones of Argentina (age range: from 164.7 to 155.7 million years ago). [1] They have been identified as belonging to small ground dwelling carnivore dinosaurs, probably Coelurosaurs. The size of the largest footprint was 4.4 cm (0.14 ft) and was made by an individual that was ...
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.
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 new footprints follow a smaller discovery in the area in 1997, when 40 sets were uncovered during limestone quarrying, with some trackways reaching up to 180 meters in length.
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.
The footprints, dating back to the Early Cretaceous period, were found in Brazil and in Cameroon, researchers wrote in a study published Monday by the New Mexico Museum of Natural History & Science.
