ABSTRACT - In 1921, Hollis and Neaverson listed 135 and varieties of foraminifera from the Gault Phosphatic Nodule Bed at Ford, Buckinghamshire, England. The material has been reexamined, the list is brought up to date and the species are figured. The Collection has yielded a diverse and well preserved foraminifera1 fauna of 90 species. Nodosariacea are the dominant group, though Ataxophragmiacea, Hedbergellacea and Mitiolacea are abundant. The recorded assemblages allow us to date the Phosphatic Nodule Bed at Ford as belonging to the uppermost Euhoplires luutus Zone to lower part of Morfoniceras inflaturn Zone within the standard ammonite zonation. J. Micropalaeontol. 16(1): 73-84, May 1997.

INTRODUCTION Ford for phosphatic nodules is not known exactly. In their Hollis and Neaverson (1921) published a short paper on the paper, Hollis and Neaverson (1921) commented that the Gault foraminifera from the workings for phosphatic nodules at workings from which Hollis had collected his material in 1919 Ford, four miles southwest of Aylesbury, Buckinghamshire were abandoned and nothing remained but the spoil-heap which (England). They listed 135 species and varieties of foraminifera was by then (1921) completely grassed over. The available but neither descriptions nor illustrations were given by the information, about the fields where the workings are said to authors. After their paper no other workers have given have been (Fig. 1), was provided by the locals or elderly relatives additional infomiation about the foraminifera of the Gault at of the locals to the Buckinghamshire County Museum (pers. Ford. In fact, no references to the paper of Hollis and comm. Ms K. M. Hawkins, Keeper of Biology and Geology of Neaverson (1921) have been found in the Early that Museum). literature of Great Britain except for one by Crittenden (1988: p. The only description of the nodules beds is that of Keeping, 19, Unpublished Ph.D. Thesis, Plymouth Polytechnic). who saw earlier workings near Ford in 1876. According to The location of the site in which the Gault was worked at Jukes-Brown, who incorporated his observations into his

Keeping’s remarks include the more ‘critical’ than in the time of Hollis and Neaverson who following: were under the heavy influence of Chapman and the ‘English School’. The coprolite seam is 3 to 4 inches thick and is constant throughout the pit, though the bed is irregular in position. The MATERIAL irregularity is of two kinds, the commonest being slips of a few The state and characteristics of the collections are described inches (4 to lo), cutting off the seam with a clear face marked by below. slickensides; in other cases the bed is bent downwards to a similar extent, and this bending is due, I am inclined to think, to Buckinghamshire County Museum (Aylesbury) subsequent folding and not to irregularity of deposition. The set consists of slides made of cedar-wood, originally without The matrix of the seam is a stiff calcareous clay crowded with cover-glasses (covered in the course of this study). The accession phosphatised shells and lumps of ‘coprolite’which in my cursory register, number 38, dates from 29 January 1920, and to quote search, I could not prove to have suffered from erosion previous from it, describes the collection as consisting of ‘108 microscope to being embedded in the Gault, while some of them, such as slides, foraminifera from Gault, Ford, Bucks., collected by Hamites were in such a condition that they could not have Hollis 1919’. They are well set out and labelled but the sustained much knocking about on a shore. information on them is limited. The labels are arranged in horizontal orientation and comprise on the left side the generic Above the [nodule] bed comes a hard clay with iron-stained joint and/or specific identification and the locality and unit (Gault, planes, which is covered by a true clay, somewhat lighter in Ford, Bucks.) and on the right side the specific classification, or colour than ordinary Gault, and containing a second irregular nothing. On the back of the slides is written ‘E. Hollis 1919’ and coprolite zone in a series of lenticular patches. Its nodules are the slide number (see Tables 1 & 2). As it now stands, the smaller than in the regular seam below. collection includes 124 slides (Trays 38:20). Of them, 17 slides It should be noted that the emphasis on structural relationships contain specimens as yet unidentified (perhaps not originally in this account may be explained by the fact that Keeping was registered) and 107 slides with identified specimens. Of the 107, teaching geology at Aberystwyth at this time and attempting to four have specimens with only generic classification [Nodosaria work out the structure of Plynlimmon! (two slides), Pleurostornella (one slide) and Pulvinulina (one Jukes-Brown visited the workings in 1885 after they had been slide)], two have specimens left in open nomenclature (Nodosaria abandoned but was able to collect fossils. Collections were also sp.) and 101 have specimens with specific identification. Of all made by a local schoolmaster (Mr Hayter of Monks Risbor- the species and varieties that are identified on the slides, 106 are ough) which put together with those of Keeping presented a included in Hollis and Neaverson’s list published in 1921 and 28 ‘curious assemblage for the Lower Gault’, including ‘Ammo- are not included. In addition, there are 29 species on the list nites’ auritus, cristatus and lautus. which were not found in the slides (see Tables 1 & 2). Hollis and Neaverson in their remarks on the ammonites said, Natural History Museum (London) Judging by specimens of ammonites in the Bucks. County As in the Aylesbury collection the slides are made of cedar-wood Museum, Aylesbury, the deposit worked belonged to the zones and without cover-glasses. The labels are arranged in the same of auritus and H. luutus. At the typical locality of way. The only difference is that there are no labels on the back Folkestone, these zones occupy 17 feet out of a total of 99 feet of the slides. The accession register indicates that the material for the whole of the Gault; but at Ford only three or four feet was deposited by E. Hollis in 1926 and the register numbers are seem to have been worked. Critical zonal study is, of course, from P23018 to P23232 (Tray 494). All the slides have specific impossible; . . . identification and of those, 56 are included in the published list We were pleasantly surprised to discover that there were three of Hollis and Neaverson, 10 are not in it and 79 species and different sets of slides of the Hollis and Neaverson Collection of varieties of the list were not found in the slides (see Tables 1 & the Gault at Ford. One set is located in the Buckinghamshire 2). County Museum (Aylesbury, England), the other one in the Natural History Museum (London, England) and the last one in Micropalaeontological Museum, University of Wales (Aberyst- the Micropalaeontological Museum of the University of Wales WYth) (Aberystwyth, Wales). The first two sets in the Museums were This last set consists of 47 slides, also made of cedar-wood, donated by E. Hollis while the third one was eventually originally without cover-glasses and now with them, attached in deposited at Aberystwyth when acquired by Prof. A. Wood the course of this work. The labels on the slides are arranged in from Neaverson who had been his research supervisor at vertical orientation. The label includes at the top the following Liverpool University. items: ‘Foraminifera, Gault, Ford, Bucks., Aug. 1919, Eng.’. The aim of this work is to bring up to date the list of The generic and specific identification is written down in ink or foraminifera of the Hollis and Neaverson paper, document the in pencil at the bottom of the label. The accession number is three scattered collections of slides and their contents and JH.389 and now all the slides have been numbered (see Tables 1 illustrate all the species, which are mostly represented by very & 2). Two of the slides contain specimens as yet unidentified, well preserved specimens. On this basis we will attempt to relate another two with only generic classification (Bulimina and the fauna to the modern, foraminiferal biostratigraphy of the Nodosaria) and 43 with specific identification.

However, looking at the stratigraphical distribution of foraminifera as seen in several key sections of southern and eastern England, Northern Ireland, northwestern Scotland and the North Sea Basin (Carter & Hart, 1977; Hart, 1973, 1990; LJ Hart et al., 1981, 1989, 1990) it is apparent that some of the P species recorded in the Gault at Ford, such as Haplostiche? ~~ P 5 sherborni Chapman, Eggerellina mariae Ten Dam, Tritaxiu E varicosum R pyramidata Reuss, Textularia chapmani Lalicker, Quinquelocu- lina antiqua (Franke), Frondicularia pinnaeformis Chapman and Vuginulina mediocarinata Ten Dam, are indicative of the Upper G A M. inflaturn Albian.

Zone (orbignyi-varicosum-lowermost auritus? Subzones) of the Albian ammonite zonation (see Fig. 2). DISCUSSION: AGE OF THE ASSEMBLAGES It must be noted that Hart’s treatment of the ammonite zones Many of the species recorded in the Phosphatic Nodule Bed of differs slightly from that of Owen (1971, 1973, 1975) in that the the Gault at Ford are also present in the Chapman Collection of cristatum Subzone is placed in the lautus Zone, i.e. the Middle the Gault of Folkestone (England) which has been examined in Albian rather than the Upper Albian.

These apparently contradictory Although Hart (1973) states that his faunal scheme, ‘can, results could be due to different approaches in the procedures unfortunately, only be described as being of local application,’ used to pick and count the specimens. the type Albian at L‘Aube, again shows a similar, major faunal The recorded assemblages at Ford, which are dominated by change over the Middle-Upper Albian boundary (lower-upper the superfamily Nodosariacea, do not seem to be typical of Gault boundary). Here, as at Folkstone, the passage to the the Middle Albian because in that interval the dominant group Upper Albian is marked by the appearance of Arenobulimina is the Superfamily Robertinacea (e.g. Hart & Carter, 1975; Hart chapmani Cushman and Frondicularia pinnaeformis Chapman et al., 1981, 1989). At the same time they are not quite the and their overlap with Epistomina spinulifera (Reuss) (see table 3 same as the typical assemblages of the Upper Albian because of Magniez-Jannin, 1975). in the upper part of the Gault Clay Formation, the fauna totally changes and becomes dominated by agglutinated taxa ACKNOWLEDGEMENTS although nodosarids and gavelinellids are quite numerous (Hart, The help of Ms K.
