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.
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 more than 100 trackways, made up of more than 1500 individual footprints, were made by both biped and quadruped dinosaurs. The tracks occur in limestone of the Jurassic Morrison Formation. The site formed along the shore of a large freshwater lake at the time the tracks were made.
The East Berlin Formation is an Early Jurassic geological formation in New England, United States. Dinosaur footprints and trackways are abundant in this formation. These tracks include Eubrontes (belonging to medium-sized-theropods similar to Dilophosaurus), Anchisauripus (belonging to small theropods like Coelophysis), and Anomoepus (belonging to indeterminate small ornithischians).

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.
Experts believe that the footprint was most likely left by a dinosaur (grallator) that stood about 75 centimeters (29.5 inches) tall and 2.5 meters (about 8 feet) long and walked on its two hind feet. [11] [12] The scientists called the girl's discovery "the finest impression of a 215 million-year-old dinosaur print found in Britain in a decade ...
The discovery was announced just a few months after a team of paleontologists found matching dinosaur footprints on what are now two different continents, separated by thousands of miles of ocean.
