It is shown in this paper that deposits virtually identical with those at Westleton extend over an area of about ninety square miles in north-east Suffolk and also occur in a much smaller area in south-east Norfolk. Elsewhere, however, all the deposits of Prestwich's Westleton Beds differ in various ways from those of the type-locality. None of these other deposits can be shown to pass laterally into those of the type-locality and some are certainly younger. Hence it is proposed that they should now be excluded from the Westleton Beds, which would thus be reduced to a relatively uniform formation of restricted areal extent.
It is thought that the Westleton Beds, as here redefined, are older than the Lowestoft Stage and younger than most of the Baventian Stage. Their marine origin is confirmed, and it is suggested that they were laid down to a large extent as beach-plain deposits, similar to those at Dungeness, on a shoreline which was prograding from north-west to south-east.1 aHey, R.W.  uhttps://neogenebryozoans.myspecies.info/hey196701340nas a2200133   4500008004100000245009200041210006900133260001200202490000800214520087400222100001801096700002201114856007001136       1996                        eng d00aA gravel beach-rip channel system: the Westleton Beds (Pleistocene) of Suffolk, England0 agravel beachrip channel system the Westleton Beds Pleistocene of  c01/19960 v1073 aThe Westleton Beds of northeast Suffolk, England, represent a Pleistocene gravelly shoreline within which three facies are distinguished. A large-scale, cross-stratified, gravel-dominated facies (A) dips predominantly offshore and is interpreted as a beach-face deposit. This facies passes seawards into a 'transitional' zone characterized by a horizontally stratified sand facies (B). This is incised into, and replaced seawards, by a third facies (C) deposited in channel-forms. Nearshore these channels are gravel-filled; further offshore they are regularly spaced, up to 2 m deep, their bases commonly being rimmed by gravel which fines upwards into sand. Several such fining-upward pulses are present in the infill of some of the larger channel-forms. It is suggested that these channels were cut and infilled by sporadic high-energy seaward-directed rip-currents.1 aMathers, S.J.1 aZalasiewicz, J.A.  uhttps://neogenebryozoans.myspecies.info/mathersandzalasiewicz199600976nas a2200109   4500008004100000245007100041210006500112490000700177520060800184100001800792856005600810       1983                        eng d00aThe stratigraphy and structure of the Crag of mid-Suffolk, England0 astratigraphy and structure of the Crag of midSuffolk England0 v943 aGlauconite-coated flints at the base of a recently recognized spread of Crag deposits are thought to have been derived from a formerly more extensive basal Bullhead Bed of the Thanet Beds. No lithological basis has been found for subdividing the Crag into Norwich and Red Crag, although the faunal criteria for separation these two Crags is of chronological significance. A number of sub-drift northeasterly trending faults and fault-guided Crag basins have been identified. The age of these structures is thought to be early Pleistocene and there was probably syndepositional movement along the faults.1 aBristow, C.R.  uhttps://neogenebryozoans.myspecies.info/bristow198301478nas a2200157   4500008004100000245006400041210006000105490000800165520099500173100002001168700002101188700001601209700001801225700001701243856006001260       1997                        eng d00aThe Red Crag and Norwich Crag formations in eastern Suffolk0 aRed Crag and Norwich Crag formations in eastern Suffolk0 v1083 aThe Red Crag Formation of eastern Suffolk was deposited in structurally controlled basins during the Pree-Ludhamian, Ludhamian and Thurnian stages. A regression during the Thurnian was followed bya transgression during the Antian/Bramertonian Stage, with the Norwich Crag Formation resting unconformably on strata as old as Upper Cretaceous. A regression during the Baventian Stage led to the formation of a complex of shoreface gravels (Westleton Beds) and intertidal clays at the mouth of a river which flowed from the English Midlands to reach the sea in the Southwold area. The Chillesford Clay Member was formed penecontemporaneously at the estuary of the proto-Thames, further south. A further marine transgression occurred during the Pastonian. The Pre-Ludhamian, Antian/Bramertonian and Pastonian transgressions are tentatively correlated with the reflectors respectively at the base of the Westkapelle Ground, Smith's Knoll and Winterton Shoal formations of the southern North Sea.1 aHamblin, R.J.O.1 aMoorlock, B.S.P.1 aBooth, S.J.1 aJeffery, D.H.1 aMorigi, A.N.  uhttps://neogenebryozoans.myspecies.info/hamblinetal199700983nas a2200109   4500008004100000245017600041210006900217490000800286520050600294100001600800856005700816       2011                        eng d00aField Meeting to the Bawdsey Peninsula, Suffolk, England, 22nd May 2010, to examine London Clay, Coralline Crag and Red Crag deposits.

The boreholes proved three members distinguished on the basis of grain size, sorting, carbonate content and fauna. The oldest, the Ramsholt Member, rests unconformably on the Palaeocene-Eocene London Clay Formation. It comprises a basal phosphorite-rich gravel with shelly mud-rich sands above. The Sudbourne Member unconformably overlies the Ramsholt Member and consists of cross-stratified, well-sorted carbonate sands, laid down as a tidal sand ridge. A third member, the Aldeburgh Member is found only in the northern part of the outcrop where it overlies the Ramshot Member. It consists of mud-poor, moderately sorted carbonate sand, and is probably the offshore (deeper water) equivalent of the Sudbourne Member.1 aBalson, Peter, S.1 aMathers, S.J.1 a  uhttps://neogenebryozoans.myspecies.info/balsonetal199300624nas a2200109   4500008004100000245006600041210006300107490000800170520026600178100001600444856005400460       2005                        eng d00aField Meeting: Coastal Suffolk Crag weekend, 23-25 April 20040 aField Meeting Coastal Suffolk Crag weekend 2325 April 20040 v1163 aThe Coralline, Red and Chillesford Crags were studied in coastal Suffolk, paying particular attention to the depositional environments indicated by the sedimentology and fauna.
