Researchers and quarry workers have uncovered a massive dinosaur "highway," which includes hundreds of footprints left by some of U.K.'s biggest dinosaurs.
The tracks were uncovered at Dewars Farm Quarry in Oxfordshire and date back to the middle of the Jurassic Period (201.3 million to 145 million years ago). It is the largest dinosaur footprint site in the U.K., researchers said.
