SALTERFROM CLIFF QUARRY, COMPTON MARTIN, MENDIP HILLSBY MURRAY MITCHELLBIOGRAPHICAL INTRODUCTlONClifford Barnett Salter was born in Bristolin 1910, the only child of Henry and DoraSalter. He was educated at Bristol GrammarSchool w<strong>here</strong> his interest in natural scienceswas quickly recognised. In 1926 he wasoffered the opportunity of further education,but his father, who was chief accountant in asubsidiary firm of the Imperial TobaccoCompany, arranged for him to he a traineet<strong>here</strong>, with security of employment for life -all important during that time of deepdepression. ClifPs interests in thecountryside never waned and years later,after he had changed his job, a move toCompton Martin enabled him to follow manycountry pursuits. Not far from the villagelay Cliff Quarry, a small quarry in theCarboniferous Limest~ne which had producedstone for housebuilding and road making;working had ceased in 1956 and it was whenexploring this quarry that Cliff made thediscovery that enabled him to amass avaluable collection of fossils. His untimelydeath in 1971 prevented him from makingfurther discoveries in this field of geologyw<strong>here</strong> amateurs have always made (and continueto make) such valuable contributions (Figs. 1-51.HISTORY OF THE COLLECTIONCliff Salter made a notable contribution togeology by amassing a very large collectionof fossils from the Carboniferous Limestoneat Cliff Quarry (NGR ST5415681, ComptonMartin, in the Mendip Hills, Somerset. Thefossils from this quarry have been known fora long time (e.g. Sibly 1906, p.3511, hutCliff Salter's meticulous work resulted inone of the largest collections ofCarboniferous Limestone fossils ever madefrom a single locality.Cliff's interest in geology and fossilcollecting was aroused by finds of ammonitesand other fossils from the Jurassic rocks ofDundry Hill, south of Bristol, and it was ahappy chance that turned his attention to thefossils from Cliff Quarry. He and his wifeEsm'e had bought a seventeenth century cottage(The Long House) in the village of ComptonMartin as a weekend retreat; as a break fromthe toils of conversion work, they would taketheir dogs for walks in the hlendip Hillswhich form the high ground south of thevillage. It was not long before ClifPseagle eye noticed that the limestone of CliffQuarry was richly fossiliferous. Hisinterest was fired by this discovery and, onlooking more closely, he found a bed oflimestone in a state of weathering thatenabled even the smallest and most delicatefossils to be extracted from the rock.Fig.1 Cliff Salter (1910-1911).Photograph taken in 1968.Boxes of this weat<strong>here</strong>d limestone weregat<strong>here</strong>d up and carted back to Bristol. Thedining room of the Salters' house at 25Cotham Road was converted into a workshop andlaboratory, and for a number of years Cliffdevoted every spare moment to breaking downthe limestone blocks and cleaning anddeveloping the fossils that he found. Thesight of Cliff, hunched over his microscopevery early every morning in the large frontwindow of his house, roused the interest andcuriosity of passers by; some were driven toenquire about ClifPs labours, hut most neverappreciated what it was that drove him tosuch toil and effort. While this work was inprogress, the Salters' domestic help used togrumble at the dust Cliff created when he was'scratching at his offals'! He sorted thefossils into different species and storedthem with great care so that he was able tokeep a check on the wide range of forms thathe collected. He developed his owntechniques, modifying instruments such asdental tools, for extracting the fossils -many of them very small - from the rock, andused his considerable engineering skill to

Esm6 Salter wasworking in the Geology Department of BristolUniversitv at the time. and Cliff and Esm6showed the specimens to Louise and DesmondDonovan, who realised the importance of thecollection but were unable to give muchassistance with identification.When Cliff turned to the PalaeontologicalDepartment of the <strong>Geological</strong> Survey (then atthe <strong>Geological</strong> Museum in South Kensington,London) for help, the full significance ofthe collection was immediately realised.Eventually, in 1962, the Survey was extremelyfortunate to receive this unique collectioninto its care.IMPORTANCE OF THE COLLECTIONThe C.B. Salter Collection is important inseveral ways. The numerical size of thecollection, and the great variety of speciespresent, makes it one of the most importantcollections from any Carboniferous Limestonelocality, arid certainly the most valuablefrom the Mendips. Although many of thefossils are small, the fine detail of theornament of the shells is beautifullypreserved and t<strong>here</strong> are a number of rareforms, some of which are the first recordsfrom the Mendip area.The details of the Carboniferous Limestonesection exposed in Cliff Quarry were given byGreen and Welch (1965, p.21) who listed someof the stratigraphically significant coralscollected t<strong>here</strong>. The quarry sequence lies inthe Hotwells Limestone near the top of theCarboniferous Limestone and corresponds inage with rocks exposed at Round Point in theclassic Avon Gorge section at Bristol(Vaughan 1905, p.199). This horizon is oneof the most widespread and fossiliferous ofthe late Brigantian Stage of the BritishDinantian; its distribution was brieflydiscussed by Kellaway (1961, p.64) and Georgeet al. (1976, p.17, fig.41, hut it has neverpreviously yielded such a remarkably diverseassemblage of fossils.Cliff Quarry must represent a specialecological habitat of the warm, shallow seain which the Mendip Carboniferous Limestonewas laid down. It was perhaps a shelteredarea with rich coral thickets, w<strong>here</strong> t<strong>here</strong>was little or no storm or current disturbanceof the water, so that the smallest and mostfragile shells could he preserved as fossils.Cliff Salter's great interest in the ComptonMartin fossils waned only when he had nearlyexhausted the supply of weat<strong>here</strong>d material(although a limited quantity of this preciousrock has been preserved for future study).The C.B. Salter collection, now housed at theheadquarters of the British <strong>Geological</strong> Surveyat Keyworth, Nottinghamshire, will remain alasting memorial to the many peaceful butexacting hours that Cliff spent preparing hisspecimens. It is an outstanding contributionto British Geology.CONTENTS OF THE COLLECTIONThe C.B. Salter Collection contains a widerange of invertebrate taxa, but only some ofthe important groups have so far beenproperly studied and described, and it is notyet possible to compile an exhaustive list oftaxa. The following list of initialidentifications does, however, give some ideaof the considerable range of fossils present.Gastropods (Fig.4A and B) are the moatimportant group in the Collection and Formedthe subject of a monographic study by DrRoger L. Batten of the American Museum ofNatural History in New York (see below).Other groups that have been described includethe brachiopod Isogramma (Fig.4C) an8
