The discovery was made by research groups from the universities of Oxford and Birmingham at a quarry in Oxfordshire in central England after a person who was working to remove clay with an excavator stumbled upon "unusual irregularities".
At the site, five extensive trails with tracks have now been found, with the longest one being over 150 meters.
Four of the tracks are believed to have been made by a long-necked herbivorous dinosaur, likely a Cetiosaurus. The fifth track is likely to belong to a nine-meter-long carnivorous Megalosaurus, known for its distinctive feet with three toes and claws, according to the University of Birmingham.
Emma Nicholls at the Natural History Museum at the University of Oxford calls the find "rare" and says that the area "may prove to be one of the world's largest sites for dinosaur tracks".
