Dewars Farm Quarry

51.919°N 1.217°W / 51.919; -1.217 Dewars Farm Quarry is a limestone quarry in Oxfordshire between Ardley and Middleton Stoney in which extensive tracks of dinosaur footprints were found in 2024. The tracks are similar to the nearby Ardley Trackways which were found in 1997.^[1][2]

The quarry excavates a layer of limestone which is crushed and graded for use as construction aggregate. The underlying layer contains the footprints which were formed in mudflats during the Middle Jurassic.^[1][2]
