The White Limestone Formation is a Bathonian geologic formation in the United Kingdom, dating to the Middle Jurassic, 168.3 to 166.1 million years ago.[1] Fossil sauropod tracks have been reported from the formation.[2] It is the lateral equivalent of the Blisworth Limestone. It predominantly consists of grey-yellow limestone, typically wackestone and packstone with subordinate ooidal grainstone. The Woodeaton Quarry locality has yielded microvertebrates.[3]
