“…The molluscan assemblage from Association A provides some biostratigraphical information though the critical species used in biostratigraphical schemes for late Middle Pleistocene interglacials (Keen, 1990(Keen, , 2001Preece, 1999), such as Belgrandia marginata and Corbicula fluminalis, are absent. However, three species that may be significant are present.…”

“…Many of the adult shells of V. piscinalis in the deposit are of the low-spired globular form that is regarded by Green et al (1996) as being typical of interglacial conditions in MIS 7, although this polymorphic species can only be used with care as a biostratigraphic indicator. The occurrence of P. clessini and C. crayfordensis also suggests an age no younger than this as these species are thought to have become globally extinct after MIS 7 (Preece, 1999;Keen 2001), although the representation of the former by a single shell fragment could be due to reworking. Records of the latter's occurrence in the Ipswichian Interglacial (Sparks, 1964) are due to the mistaken use of pollen biostratigraphy to identify deposits as Ipswichian, which are actually of MIS 7 age.…”

Pleistocene fluvial sediments of the Northmoor Member of the Upper Thames Formation exposed at Latton, Wiltshire, record episodic deposition close to the Churn-Thames confluence possibly spanning the interval from Marine Isotope Stages (MIS) 7 to 2. The sequence is dominated by gravel facies, indicating deposition by a high-energy, gravel-bed river. A number of finegrained organic sediment bodies within the sequence have yielded palaeoenvironmental and biostratigraphical data from Mollusca, Coleoptera, vertebrates, pollen and plant macrofossils. The basal deposit (Facies Association A) contains faunal material indicating temperate conditions. Most of the palaeontological evidence including a distinctive small form of mammoth (Mammuthus cf. trogontherii), together with the U-series age estimate of >147.4 AE 20 kyr suggest correlation with MIS 7. The overlying deposits (Facies Associations B and C) represent deposition under a range of climatic conditions. Two fine-grained organic deposits occurred within Association B; one (Association Ba) in the northern part of the pit as a channel fill and the other (Association Bb) in its southern part as a scour-fill deposit. The coleopteran assemblages from Ba, indicate that it accumulated under temperate oceanic conditions, while Bb, which also yielded a radiocarbon age estimate of 39 560 AE 780 14 C yr BP, was formed under much colder and more continental climatic conditions. The sequence is considered to represent deposition within an alluvial fan formed at the Churn-Thames confluence; a depositional scenario which may account for the juxtaposition of sediments and fossils of widely differing age within the same altitudinal range.

“…Wood, 1851)) is also quite abundant. In western Europe Meijer (1989), Keen (2001), and Gittenberger et al (2004) link the last appearance of this species with the Holsteinian Interglacial, but in Britain it also occurred in sequences assigned to both MIS 9 and MIS 7 (Roe et al 2009). It was also common in the Early Pleistocene, but in Poland it has only been found in the Mazovian.…”

“…Their age was established on the basis of the pollen analysis (Albrycht 2002b;Szymanek and Bińka 2006;Szymanek 2007Szymanek , 2008Szymanek , 2011, as well as the molluscan fauna, which included two species characteristic of the Mazovian, Viviparus diluvianus (Kunth, 1865) and Lithoglyphus jahni Urbański, 1975(Albrycht et al 1995Szymanek 2011). In Britain V. diluvianus is also regarded as an indicator of the Hoxnian stage = early part of MIS 11 (Kerney 1971;Meijer and Preece 1995;Keen 2001;Roe 2001;White et al 2013), whereas in the Netherlands it appears in both the Holsteinian and Tiglian (Meijer 1989;Gittenberger et al 2004). L. jahni is unknown from the late Middle Pleistocene in NW Europe but is known from the Augustovian (Bavelian) of Poland (Skompski 2009) and the Netherlands, where it also occurs in the Tiglian (Meijer 1989;Gittenberger et al 2004).…”

Szymanek, M. 2014. Environmental changes of the Mazovian (Holsteinian /~MIS 11) palaeolake near Szymanowo (eastern Poland) in the light of malacological analysis. Acta Geologica Polonica, 64 (2), 249-260. Warszawa.The malacofauna of the palaeolake deposits at Szymanowo (eastern Poland) was investigated. It represents the younger part of the climatic optimum of the Mazovian (Holsteinian) Interglacial (~MIS 11) and possibly the postoptimal period. The mollusc assemblage is composed of both standing and running water species, mostly connected with temperate climate. The presence of biostratigraphical indicators of the Mazovian, Viviparus diluvianus (Kunth, 1865), Lithoglyphus jahni Urbański, 1975 and Pisidium clessini Neumayr, 1875, is noteworthy. Variability in the structure and composition of the assemblage enables palaeoecological reconstruction. Changes in the water-level, vegetation and energy conditions are inferred from the malacological succession. Three stages of the lake development were distinguished. The first one is connected with deeper conditions and predominance of V. diluvianus and L. jahni. The second one, dominated by Bithynia tentaculata (Linnaeus, 1758), records a fall of the water-level and the growth of aquatic plants, evidenced by high frequencies of Valvata cristata Müller, 1774 and Acroloxus lacustris (Linnaeus, 1758). The third stage corresponds to another rise of the water-level and an increase in V. diluvianus, L. jahni, Valvata piscinalis Müller, 1774 and Pisidium henslowanum (Sheppard, 1823), which evidence some higher energy conditions.

In the case of sites in the Middle and Lower Thames valley it is also supported by terrace stratigraphy and, in particular, the relationship between the Boyn Hill/Orsett Heath terrace to Anglian till in north London (Bridgland, 1994).…”

The archaeological, environmental and geological data from Hoxnian Interglacial (Marine Isotope Stage (MIS) 11) sites from Britain are examined to elucidate the type of habitats that humans preferred during this temperate episode. The conclusion is that humans avoided lacustrine situations, but did make use of the full range of resources that fluvial environments provide. This model is strengthened by the examination of other non-archaeological Hoxnian sites. The problem of archaeological visibility in lacustrine sediment sequences is also discussed and methods of identifying other evidence of human presence are suggested that may offset the deficiencies in the lithic record. These include presence of cut-marked bone, micro-debitage and possibly charcoal in fine-grained sediments deposited in distal settings. The reasons for human selection of fluvial situations are discussed. It is concluded that these environments provide a greater diversity of animal, plant and lithic resources, but also are major route-ways through the landscape. Patterns of human site use are identified, which seem to be triggered by local changes in hydrology and drainage, themselves possibly caused by regional changes in climate. Finally, Lower Palaeolithic sites on the interfluves are discussed. Although they lack environmental or dating evidence, it is tentatively suggested that they were used during cooler episodes, when more open conditions prevailed.
