These stunning dinosaur tracks are just some of around 200 footprints uncovered in Oxfordshire, UK.
Five different sets of prints have been excavated at Dewars Farm limestone quarry, including the two shown crossing in the main image. These, along with two other sets, belonged to sauropods, possibly from the Cetiosaurus genus, which could be up to 18 metres long. The track running from bottom right to top left is from the larger of the two herbivores, with each footprint being 90 centimetres long.

A fifth set of fossil prints is from a large carnivorous dinosaur, thought to be a species of therapod called Megalosaurus. These impressions (pictured above) are slightly smaller, at 65 centimetres long.
All the tracks date to the middle of the Jurassic Period, around 166 million years ago. At this time, the area would have been a warm, salty lagoon along with mudflats.
