Rock Edge is a 1.7-hectare (4.2-acre) geological Site of Special Scientific Interest in Oxford in Oxfordshire.[1][2] It is a Geological Conservation Review site[3] and a Local Nature Reserve[4][5]

This site exposes limestone rich in coral called Coral rag, laid down when the area was under a warm, shallow sea, similar to the Bahama Banks today. It is rich in fossils derived from the coral reefs. It dates to the Upper Jurassic, around 145 million years ago.[6]
