Laycock Railway Cutting (grid reference ST678213) is a 1.3 hectare geological Site of Special Scientific Interest near Milborne Port in Somerset, notified in 1993. It is a Geological Conservation Review site.
Laycock Railway Cutting is the best single exposure of the Bathonian ’Fuller's Earth Rock’ in South Somerset. Ammonites indicating the Morrisi and Subcontractus zones of the Middle Bathonian are frequent. Ammonites are generally extremely rare at this level in Britain and their presence at Laycock is of international stratigraphic importance. The combination of features of both litho- and chrono-stratigraphical importance make Laycock Railway Cutting a key British Bathonian locality.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
