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.
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.
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 ...
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.
There are tracks from two types of dinosaur. The first type of tracks are from a sauropod and were made by an animal of 30 to 50 feet in length, perhaps a brachiosaurid such as Pleurocoelus, [20] and the second tracks by a theropoda, an animal of 20 to 30 feet in length, perhaps an Acrocanthosaurus. A variety of scenarios was proposed to ...
