Researchers in England have unearthed nearly 200 dinosaur tracks that date back 166 million years. The discovery, announced Thursday by the universities of Oxford and Birmingham, were made last summer when a worker digging up clay in a quarry in Oxfordshire noticed unusual bumps. That finding led to a week-long excavation in June which unearthed five extensive trackways that formed part of a “dinosaur highway.” Four sets of tracks were made by herbivores called sauropods, that were most likely Cetiosaurus, which measure up to 60 feet (18 meters) long. One track was made by the ferocious Megalosaurus, a carnivore with a distinctive triple-claw print., Researchers in England have unearthed nearly 200 dinosaur tracks that date back 166 million years.
