Extract

Mr. G. W. Lamplugh and the late Mr. J. F. Walker published a paper in 1903 on a fossiliferous bed at the top of the Lower Greensand, exposed in sand-pits at Shenley Hill, near Leighton Buzzard. The bed in question presented points of considerable lithological interest and was remarkable for its rich brachiopodfauna. Its position above the “silver-sands” of the Lower Greensand and below a capping of dark “shaly clay”, ascribed by those observers to the Lower Gault, led to the conclusion that it belonged to the top part of the Lower Greensand. The discovery of its fossils was considered to throw welcome light on the faunal characters of the latest Lower Cretaceous rocks in England, represented in more southern counties by relatively unfossiliferous sands.
