The brachiopod fauna from the Anderken Formation (Lower to Middle Caradoc) of the Chu-Ili Range, south-eastern Kazakhstan, is revised and described systematically. It consists of 62 species in 55 genera, of which the genera Tesikella, Olgambonites and Zhilgyzambonites (all Plectambonitoidea) and Ilistrophina (Camarelloidea) are new, and the species Bellimurina (Bellimurina) sarytumensis, Teratelasmella chugaevae, Foliomena prisca, Acculina kulanketpesica, Dulankarella larga, Kajnaria rugosa, Anoptambonites convexus, Olgambonites insolita, Zhilgyzambonites extenuata, Gacella institata, Placotriplesia spissa, Grammoplecia wrighti, Dolerorthis pristina, Austinella sarybulakensis, Plectorthis? burultasica, Bowanorthis? devexa, Pionodema opima, Parastrophina iliana, Ilistrophina tesikensis, Liostrophia pravula, Plectosyntrophia unicostata, Rhynchotrema akchokense and Nikolaispira guttula are new. Six brachiopod-dominated assemblages are recognised and defined, termed the Ectenoglossa, Tesikella, Mabella–Sowerbyella, Acculina–Dulankarella, Parastrophina–Kellerella and Zhilgyzambonites–Foliomena Associations. The relationships with contemporary faunas are assessed, and the Anderken brachiopods appear to have much in common with those of north-west China.

Human induced damage is the main taphonomic modification observed on the fossil bone assemblage of Gough's cave. Fossils from this site are very fragmentary, showing abundant cut-marks, percussion marks and peeling. Some specimens, however, are complete (ribs, vertebrae, carpal-tarsal bones and phalanges), but these elements are characterised by low marrow content where breakage to open the bone is not needed. Human remains recovered from this site show similar butchering patterns to other animals suggesting skinning, dismembering, defleshing and marrow extraction activities. Excavations during the 1986–1987 seasons showed that the human remains appear at the site randomly mixed with animal bones, with no specific distribution or arrangement of human bones. The evidence from this distribution indicates equal treatment of human and animal remains, and the analysis of cut-marks and other modifications suggests that both humans and animals were accumulated as the discarded food remains of the human population. This is interpreted as nutritional cannibalism. One exception to this is seen in the slight differences in skull treatment compared with other sites, suggesting a possible element of ritual cannibalism (cf Fontbrégoua, the French Neolithic site, ca 4000 BC).

Rocks of Lower Liassic (Sinemurian and Lower Pliensbachian) age exposed in Robin Hood's Bay, near Whitby, north Yorkshire, are described from the mapping, stratigraphical descriptions and ammonite collections made by Mr Leslie Bairstow in the years 1927–1970, and preserved in the Palaeontology Department, The Natural History Museum, London. His large-scale map of the geology of the foreshore is published on five sheets at a scale of approximately 1:5000. The stratigraphical sequence from bed 418 at the base up to bed 600.5 at the top of the Lower Pliensbachian is 163.74 m thick, and consists of the Redcar Mudstone Formation, for which four members are formally defined – the Calcareous Shale (at the base), Siliceous Shale, Pyritous Shale and Ironstone Shale Members – overlain by the lower part of the Staithes Sandstone Formation. The lowest beds exposed by the lowest spring tides are Sauzeanum Subzone, Semicostatum Zone, in age; ammonites occur in all subzones, and the only uncertain boundary is that between the Masseanum and Valdani Subzones (Ibex Zone), where there are few characteristic ammonites. Bairstow's ammonite collection consists of more than 2360 specimens, all from recorded horizons, and is notably rich in Promicroceras, Asteroceras, Eparietites and Oxynoticeras from the Obtusum and Oxynotum Zones, Echioceratids, Eoderoceras and Apoderoceras from the Oxynotum, Raricostatum and Jamesoni Zones, and Liparoceratids from the Davoei Zone, making it a primary source for Sinemurian and Lower Pliensbachian ammonite biostratigraphy. The recently proposed selection of Wine Haven at the south-eastern end of the bay as the Global Stratotype Section and Point (GSSP) for the base of the Pliensbachian Stage (ie. the world standard definition), is supported by the sequence of ammonites across the Sinemurian/Pliensbachian boundary. All previously figured ammonites from Robin Hood's Bay are listed in a systematic section that includes the evidence on which the ammonite identifications in the paper are based, and 56 of the best preserved ammonites are figured. Eparietites bairstowi sp. nov. is proposed for an early species of Eparietites and a Sowerby Collection ammonite from the Aplanatum Subzone, Raricostatum Zone, in the bay, is designated neotype of Eoderoceras armatum (J. Sowerby).

The postcranial axial skeleton of Cheddar Man (Gough's Cave 1) is represented by seventeen presacral vertebrae, the sacrum, and nineteen ribs, all of which are relatively well-preserved. Cheddar Man derives from early Holocene deposits in Gough's Cave, and the remains of his axial postcranial skeleton are described here. Comparative evaluation of the Gough's Cave 1 remains reveals an axial skeleton that falls within the range of variation in size and shape of males of the same time period, albeit towards the small end of that range (reflecting relatively short stature in Cheddar Man).

Eleven thin sections of Late-glacial and early Holocene sediments from Gough's Cave were investigated by soil micromorphology in order to complement analyses of contemporary faunal and human remains. Despite the paucity of continuous vertical and lateral stratigraphic sequences, which were the result of cave exploitation during the first half of the twentieth century, we were able to elucidate site formation processes relating to both Late-Glacial environmental conditions and the burial environment affecting human remains.
