White Limestone Formation
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. Fossil sauropod tracks have been reported from the formation. 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.
