Small patches of friable tufa associated with the cemented tufa apron of Lower Beck, Malham have yielded a land molluac fauna indicative of woodland conditions totally unlike the treeless aspect of much of the northern Pennines today. By analogy with similar faunas in southern England and Lincolnshire, an age in the Middle Flandrian is suggested for the tufa accumulation. Among the species found is Vitrea subrimata (Reinhardt) otherwise unrecorded in the Flandrian in Britain.
