Oligocene-Miocene calcareous nannofossils from the Torquay Basin,Victoria, Australia

Oligocene-Miocene rocks of the Torquay Basin contain at least 55 different species of calcareous nannofossils. These species allow zonation of an offshore subsurface section (Nerita No. 1 Well) and two onshore sections (near Torquay). The Angahook Formation and the base of the Jan Juc Formation in the Nerita No. 1 Well belong to Martini's (1971) NP 22 calcareous nannofossil Zone (early Oligocene). The NP 23 Zone could not be identified with certainty, but Zones NP 24/25 (late Oligocene) to NN 2 (early Miocene) were recognized in the Jan Juc Formation. The Oligocene-Miocene boundary is present between 122 m and 135 m below the sea floor at this site. The Puebla Formation, exposed at the sea floor, contains NN 5 spanning the early-middle Miocene boundary.

Onshore along the Torquay coast, NP 24/25 (late Oligocene) is present in the Angahook Formation; the Jan Juc Formation at Bird Rock also contains NP 24/25, except the uppermost 2.5 m which belongs to NN 1. The NN 2 Zone begins at the contact between the Jan Juc and Puebla Formations and continues upward for at least 3 m. After a covered interval, NN 4 was identified 10 m above the contact. The Oligocene-Miocene boundary is placed at the base of the hard band capping Bird Rock in the type section of the Jan Juc Formation.

Nannofossil assemblages in the Torquay sections suggest deposition in cool, shallow continental shelf waters. The assemblages in Nerita No. 1 Well also suggest cool shelf waters, although deeper than at Torquay.     

CROSS‐CHANNEL CONNECTIVITY: WEALDEN WHETSTONE IMPORTS FROM ROMAN BRITAIN TO THE CONTINENT

The purpose of this paper is to demonstrate cross‐Channel exchange of calcareous sandstone‐type whetstones derived from the Weald (Sussex, UK) in the Roman period. The presence of this particular type of whetstone at several Roman sites on the Continent – more specifically, in Belgium, France and the Netherlands – is reported for the first time. The morphology, geological provenance, petrographic characteristics and distribution patterns are discussed, based on a comparative analysis with archaeological and geological reference material. The geological analysis identifies a common geological source for the Continental finds: the very fine‐grained, thin‐bedded, flagstone‐like calcareous sandstone beds of the Lower Cretaceous Wealden Clay Formation. These sandstones were, most probably, extracted in the north‐western part of the Weald area. The distribution pattern of the archaeological material implies the importance of personal mobility, with potential military affinities.     

Shell tool use by early members of Homo erectus in Sangiran,central Java,Indonesia: cut mark evidence

Sangiran has been known as a source of fossil Homo erectus but is better known for the absence of archaeological tools. Cut mark analysis of Pleistocene mammalian fossils documents 18 cut marks inflicted by tools of thick clamshell flakes on two bovid bones created during butchery at the Pucangan Formation in Sangiran between 1.6 and 1.5 million years ago. These cut marks document the use of the first tools in Sangiran and the oldest evidence of shell tool use in the world.     

Devonian trilobites from the Shogrām Formation,Kurāgh,Chitral (NW Pakistan)

Late Devonian trilobites from horizons close to the Frasnian-Famennian boundary in the Shogrām Formation at Kurāgh, Chitral (NW Pakistan) are described. A new species of Asteropyginae, Neocalmonia chitralensis sp. nov., and a new subpecies, Neocalmonia batillifera orientalis subsp. nov., are described; these extend the range of Asteropyginae eastwards from Iran and southern Afghanistan. The Upper Kellwasser Event is located within KUR 19 of Talent et al. (1999).     

First evidence of a Late Cretaceous sea turtle from Australia

The isolated scapula of a chelonioid sea turtle is described from the Upper Cretaceous (upper Maastrichtian) Miria Formation of the Giralia Ranges in Western Australia. Character states including the wide angle of divergence between the scapular processes (possibly reaching 140°), projection of the glenoid on a constricted scapular neck, and highly vascular glenoid articular surfaces suggest affinity with dermochelyoids—the most diverse and geographically widespread clade of Mesozoic chelonioids. The Miria Formation chelonioid scapula constitutes the first definitive record of a Late Cretaceous sea turtle from Australia and is one of the few occurrences thus far documented from Upper Cretaceous–Paleogene deposits in the Southern Hemisphere.     

Early Upper Paleolithic industries of Eastern Europe

Early Upper Paleolithic sites are known in various parts of Eastern Europe, but the two main concentrations of them are the Prut-Dniester basin and the middle Don. The flint industries are divided into archaeological cultures (cultural traditions), of which some show clear archaic features (Kostenki-Streletsian, Gorodtsovian, Brynzenian, etc.), while others have no Mousteroid characteristics (Spitsynian, Telmanian, etc.). Both types of culture coexisted throughout the Early Upper Paleolithic. In some cases, it is possible to trace genetic links between archaeological cultures and to follow the transition between the Middle and the Upper Paleolithic. The radiocarbon age of the oldest Upper Paleolithic sites in the Russian Plain is about 40,000 B.P., but some sites may be older. The Early Upper Paleolithic ended about 24,000–23,000 B.P. In the Crimea, the Middle-Upper Paleolithic transition appears to have taken place at about 20,000–18,000 B.P.     

Prehistory of the Upper Yenisei area (southern Siberia)

Our understanding of the prehistory of the Upper Yenisei area is based on several key multilayered sites, which provide an excellent opportunity for the investigation of long-term culture change and the reconstruction of culture history. The earliest traces of prehistoric people in the region date to the Sartan glacial. Ui I is dated to ca. 22,000–17,000 B.P. and belongs to the middle phase of the Yenisei Upper Paleolithic, predating the period of the Final Paleolithic Afontova culture (16,000–10,000 B.P.). The Early Holocene period remains little known; there is only one assemblage (the lower cultural layer of Sosnovka Golovan'skaya) which may be attributed to the Epipaleolithic. In the seventh and sixth millennia B.P., the aceramic Early Neolithic (the uppermost cultural horizons of Maina and Ui II, Ust'Khemchik 3, etc.) was widespread and was replaced by the Late Neolithic Verkhneeniseisk culture in the fifth millennium B.P. This was succeeded by the Eneolithic Afanas'eva culture at the end of the fifth millennium B.P. and, later, by the Bronze Age Okunev culture (until the twelfth century B.C.). From the eighth to the second centuries B.C., Scythian cultures flourished in the area, until the invasion of the Huns. All of these stages of the Holocene culture sequence are represented in the stratified site of Toora-Dash.     

An archaeometric contribution to the characterization of Renaissance maiolica from Urbino and a comparison with coeval maiolica from Pesaro (the Marches,central Italy)

The results of an archaeometric trial study performed on an important finding of Renaissance maiolica (mid‐15th to early 16th century) from the Ducal Palace of Urbino are presented. Mineralogical–petrographic data (XRD, OP, SEM–EDS) and chemical characterization (ICP/AES–MS: major and trace elements) of both ceramic bodies and glazes were compared with similar data provided on coeval maiolica found in archaeological excavations in Pesaro, now stored in the city's Municipal Museum, in order to verify an origin of the potteries from common (Pesaro) or different (Pesaro and Urbino) production centres. The results indicate that ceramic bodies were produced with quite similar illitic–calcareous clays, most probably taken from the same local Pliocene Formation. Similarities were also found concerning the glaze's glass (silica–lead), colourants (cobalt, copper and manganese) and pigments (lead antimonate and cassiterite).     

Chagyrskaya Cave:A Middle Paleolithic Site In The Altai

This article presents the results of multidisciplinary studies conducted at Chagyrskaya – an Upper Pleistocene karst cave in the northwestern Altai where Middle Paleolithic stone tools and fossil remains of Neanderthals were found. Taphonomic aspects of the site are addressed, and results of science-based analyses including radiocarbon and paleomagnetic dating are presented. The deposits are similar to loess-like Upper Pleistocene loams of Western Siberia. Among the Middle Paleolithic industries of the Altai, the Chagyrskaya industry is paralleled only by that of Okladnikov (formerly Sibiryachikha) Cave. Both represent a local Middle Paleolithic Mousteroid facies, named Sibiryachikha after the eponymous site.     

Composite projectiles and hafting technologies at Ohalo II (23 ka,Israel): analyses of impact fractures,morphometric characteristics and adhesive remains on microlithic tools

This study focuses on the correlation between the production of backed microliths in the Levant during the late Upper Palaeolithic and their use as side elements of composite projectile weapons. The investigation is based on assemblage sample of microliths from Ohalo II, a 23,000 years old submerged campsite, and involves analyses of diagnostic impact fractures, location of adhesive remains and morpho-metric characteristics of the tools. Two distinct adhesive materials have been also analyzed, and the preliminary results indicate the use of both calcareous and organic substances.

A new crustacean clam shrimp (Spinicaudata: Eosestheriidae) from the Upper Triassic of Argentina and its importance for ‘conchostracan’ taxonomy

A new species of a fossil crustacean clam shrimp (Spinicaudata: Eosestheriidae) Menucoestheria wichmanni is described from the lower Upper Triassic Vera Formation (Los Menucos Complex) in Río Negro Province, southern Argentina. This discovery represents the first record of this family in the Triassic of Argentina and the southernmost record of South American Triassic ‘conchostracans’ (Spinicaudata). The new species shows close affinities with Middle Jurassic faunas from Antarctica and offers important data on the taxonomy (notably the use of ornamentation characters), palaeobiogeography (as South America hosts the oldest-known fossils of this family) and evolution of the Gondwanan faunas. Other South American eosestheriid species are tentatively recognized. Menucoestheria is hypothesized to be the ancestral form of the Triassic–Jurassic Gondwanan eosestheriids. Relationships between European and Gondwanan eosestheriids remain unresolved.     

Palynology of the Jurassic-Cretaceous transition in the Rajmahal Formation,West Bengal,India

Borehole PGD-1A penetrated Cretaceous Rajmahal Formation and underlying Triassic Panchet Formation between 288–423.51 m. Palynoassemblages recovered within the Mesozoic sequence are assigned to three palynozones closely comparable to Australian assemblages. The oldest palynozone is the Verrucosisporites-Lundbladispora zone, which occurs between 373.5–376 m in the uppermost Panchet Formation. The first occurrence of Callialasporites turbatus occurs at 373.5 m and signals the presence of Jurassic deposits. The overlying Infratrappean greyshales (371.5–354 m) of the Rajmahal Formation is represented by the Murospora florida palynozone of Late Jurassic age. The youngest palynozone identified is the Cicatricosisporites australiensis zone which occurs within the Inter-trappeans (346.35–295.0 m) of the Rajmahal Formation. Based on ages assigned to the M. florida and C. australiensis zones in Australia, the Rajmahal Formation is dated as Oxfordian-Berriasian. The first appearance datums (FADs) of Cicatricosisporites australiensis, Crybelosporites stylolsus, Aequitriradites spinulosus and Lycopodiacidites dettmannae suggest that the Jurassic-Cretaceous boundary probably lies just within the interval 346.35–328.81 m in Inter-trappean bed II.     

Oceanic palaeoenvironment of the Miocene Fyansford Formation from Fossil Beach,near Mornington,Victoria, interpreted on the basis of Ostracoda

Study of an ostracode assemblage from the Miocene Fyansford Formation near Mornington allows determination of the principal characteristics of the hydrologic environment at that time.

Palaeodepth was upper epibathyal (about 150–250 m). The oxygen minimum zone mostly was weakly demarcated at about O₂ 5 ml/l. Productivity was good and the benthic ostracode microfauna was rich and varied. Occasionally, a sudden and strong increase in productivity occurred which correlated to a rapid and well marked increase in the oxygen minimum zone. Physico-chemical factors, which developed following bacterial breakdown of organic matter that had accumulated on the bottom, are reflected in Bradleya shells by distinct signs of aggradation/degradation. A few allochthonous forms from the nearby continental shelf were transported downwards onto this part of the upper slope. Bottom currents contributed (by furrowing) to the formation of calcareous ‘hard grounds’.

Bradleya morningtonensis n.sp. is described as new.     

Exponential Decline in the Dispersal of Stone Artefacts in Roman Britain: Further Expressions of Trade

Several industries that exploited stone are known to have sprung up in Iron Age–Roman and Roman Britain. They include the fashioning of rotary querns from the Upper Old Red Sandstone of the Forest of Dean and the Lower Cretaceous Hythe Beds (Lodsworth rock) of West Sussex, the production of whetstones from sandstones in the Weald Clay Formation of the north‐west Weald, and the manufacture of a wide range of products from the Upper Jurassic Purbeck Marble of south‐east Dorset. The dispersal of goods from these sources is found to exhibit a similar exponential decline with distance to that previously demonstrated for prehistoric stone artefacts and Romano‐British ceramics. Evidently, interactions at settlements led to the retention of a roughly constant proportion of the goods brought there.     

Palaeogeographic setting of a deep-water trilobite fauna from the Early Devonian (Pragian) of the Upper Yarra,central Victoria. Phacopidae of Victoria,Part 3

A Pragian (Early Devonian) trilobite fauna from the Norton Gully Formation in the Upper Yarra area of central Victoria consists exclusively of the phacopid Prokops moorei sp. nov., a species with a highly variable visual surface including greatly reduced and blind morphologies. Several trilobites are preserved as moult assemblages, but most occur as isolated tergites on bedding-planes crowded with dacryoconarids and small bivalves. The autecology and taphofacies of the fauna indicate a deep-water setting, with the biofacies associations closely resembling deep-water assemblages described from Devonian sequences elsewhere. The distributions of laterally equivalent late Pragian facies from eastern areas of the Melbourne Zone indicate an inclined shelf between Lilydale and the Upper Yarra area, deepening eastwards from shoreline to outer shelf settings. To the northwest and northeast of the Upper Yarra area, the shelf was bounded by tectonically active margins associated with the converging Benambra Terrain, and to the south by the Waratah Bay Platform.     

Trilobite faunas and palaeoenvironmental setting of the Silurian (early Ludlow) Melbourne Formation,central Victoria

Trilobites are common faunal elements in the Melbourne Formation, a unit of early Ludlow (upper nilssoni Biozone) age, which crops out extensively in the Darraweit Guim Province of the Melbourne Zone, central Victoria. New diagnoses are given for species previously described, including Maurotarion euryceps (McCoy, 1876; = Cyphaspis spryi Gregory, 1901), Raphiophorus jikaensis (Chapman, 1912; = Ampyx yarraensis Chapman, 1912), Cromus simpliciculus (Talent, 1964), Cromus spryi (Chapman, 1912), Sthenarocalymene kilmorensis (Gill, 1945; = Gravicalymene hetera Gill, 1945) and Trimerus harrisoni (McCoy, 1876). A new phacopid genus, Orygmatos is described, represented by the species O. yanyeani gen. et sp. nov. Other species newly described include Cromus melbournensis sp. nov., Arcticalymene australis sp. nov., “Ananaspis” woiwurrungi sp. nov. and Kettneraspis hollowayi sp. nov.

Species composition of the trilobite fauna varies spatially, and a number of distinct assemblages can be defined. Abundant trilobite moult configurations are conclusive for interpretation of the benthic fauna as autochthonous, inferring depth estimations based on benthic community distribution to be valid. A depth-related succession of communities is recognised and indicate the Melbourne Formation was deposited at relatively shallow depths on a broad, eastwardly deepening shelf, with deposition dominated by storm processes. The palaeoenvironment comprised a BA-1 community including the Arcticalymene australis trilobite assemblage, restricted to very shallow depths (～20 m) on the SW coastal margin of the shelf and preserved in proximal tempestite lithologies; and a BA-5 community group containing three distinct trilobite assemblages dominated by species of Cromus and a deeper water fauna, preserved in distal tempestite lithologies and ranging widely over the shelf at depths in the range of maximum storm wave base (～50 – 80 m).     

On the Supposedly Young age of Angara Alluvial Sediments Based on the Findings of Salvage Excavations in the Flooding Area of the Boguchany Hydroelectric Plant

Based on the stratigraphy of Paleolithic sites on the northern Angara, the Upper Pleistocene and Holocene history of the region is reconstructed. Findings of recent salvage excavations in the Boguchany flooding zone as well as the evidence of Quaternary geology, geomorphology, neotectonics, and archaeology jointly disprove the “young Angara” model proposed by G.I. Medvedev and other “geoarchaeologists.” The principal event postulated by that model – the alleged disastrous outburst of the Angara along the Baikal channel 12–7 ka BP is supported neither by the relief nor by the Upper Pleistocene and Holocene sedimentation record nor by the stratigraphy of the Paleolithic sites on the northern Angara.     

Infrared radiofluorescence (IR-RF) dating of middle pleistocene fluvial archives of the Heidelberg Basin (Southwest Germany)

The infrared radiofluorescence (IR-RF) dating technique was applied to eight fluvial samples that were collected from two sediment cores at the Heidelberg Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the IR-RF derived ages of the samples it was possible to establish a chronological framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin. The results allow us to distinguish between four main periods of aggradation. The lowermost sample taken from 100 m core depth lead to an IR-RF age of 643 ± 28 ka pointing to a Cromerian period of aggradation (OIS 17–16). For the Elsterian it is now possible to distinguish between two aggradation periods, one occurring during the Lower Elsterian period (OIS 15) and a second during the Upper Elsterian period (OIS 12–11). For the so called Upper interlayer (or “Oberer Zwischenhorizont” — a layer of organic-rich and finer-grained deposits), the IR-RF results point to a deposition age of around 300 ka, with samples taken directly on top and out of this layer yielding IR-RF ages of 288 ± 19 ka and 302 ± 19 ka, respectively. Hence, the measured IR-RF ages clearly point to a deposition during the Lower Saalian period (OIS 9–8) whereas earlier studies assumed a Cromerian age for the sediments of the Upper Interlayer based on pollen records and also mollusc fauna. The new IR-RF dataset indicates that significant hiatuses are present within the fluvial sediment successions. In particular the Eemian and Upper Saalian deposits are missing in this part of the northern Upper Rhine Graben, as the 300 ka deposits are directly overlain by Weichselian fluvial sediments. It is obvious that time periods of increased fluvial aggradation were interrupted by time periods of almost no aggradation or erosion which should have been mainly triggered by phases of increased and decreased subsidence of the Heidelberg Basin.     

Mammalian fauna from Palaeolithic sites in the Upper Yenisei River basin (southern Siberia): Review of the current zooarchaeological evidence

The palaeontological data on mammal remains from two Middle Palaeolithic (ca. 125 000 years ago – 27 200 BP) and 34 (ca. 34 000–12 000 BP) Upper Palaeolithic cultural complexes in the upper part of the Yenisei River basin (southern Siberia) are considered. General features of the faunal assemblages are established. Several issues are discussed, including (a) changes in species composition through time and palaeoenvironmental implications of the zooarchaeological records; (b) patterns of human exploitation (hunting) of mammals; (c) issue of mammoth hunting and (d) possibility of domestication of dog in the late Upper Palaeolithic in the Yenisei River basin.
