Some 200 dinosaur footprints dating back 166 million years have been unearthed in a find believed to be the biggest in the UK. The extraordinary find was made by a team of over 100 people in the Dewars Farm Quarry, in Oxfordshire. It expands upon previous paleontology work in the area and offers greater insights into the Middle Jurassic period. The trove of documentation could shed light on the size of the dinosaurs, how they walked and the speed at which they moved.
