Abstract We examine three distinctive biostratigraphic signatures of humans associated with hunting and gathering, landscape domestication globalization. All have significant fossil records regional importance that can be correlated inter‐regionally help describe the developing pattern human expansion appropriation resources. While none individual first or last appearances provide a globally isochronous marker, all overlap stratigraphically, in they are part continuum change, complex...
A punctuated 103.3 m thick succession of upper Palaeogene to Quaternary sediments has been recovered in a borehole from the Hebrides Slope, west Britain. The proved 11.2m Oligocene, carbonate-rich muds at base, unconformably overlain by 2.85 middle Miocene, glauconitic sands. This is turn 89.25 predominantly Plio-Pleistocene sands and muds, with Holocene sea-bed veneer. post-Miocene subdivided into two units: sand-dominated, Pliocene lower Pleistocene, Lower MacLeod sequence between 67.82 m,...

In this article, we present a glaciotectonic model for raft emplacement based on study of large‐scale and small‐scale deformation structures associated with the accretion chalk rafts at three Middle Pleistocene sites north Norfolk coast, eastern England. Detailed structural measurements taken from localities indicate an overall sense ice movement towards south/southeast, suggesting source area located to coast in offshore North Sea. Provenancing rafts, analysis foraminifera, also indicates...
Abstract Examination of two radiocarbon‐dated vibrocores taken from south St Kilda at a water depth about 155 m, short distance within the maximum position Late Devensian (Dimlington Stadial) ice sheet, suggests that Basin became free glacier after 15250 yr BP. Sedimentation in shallow, low energy, high arctic, muddy environment continued until 13500 There followed higher energy temperate episode during which depths were roughly 40 m: this is correlated with latter part Windermere...
Abstract The Mississippian Strathclyde Group of the Midland Valley Scotland yields some earliest non-marine ostracods. succession records shallow marine, deltaic, estuarine, lagoonal, lacustrine, fluvial and swamp environments representing a series staging-posts between fully marine limnetic settings. Macrofossils ostracods are assigned to marginal brackish freshwater based on their faunal assemblage patterns. Key Geisina arcuata , Paraparchites circularis n. sp., Shemonaella ornata sp....
Abstract The term ‘Anthropocene’ has been proposed to indicate a geological interval characterized by global anthropogenic environmental change. This paper attempts recognize method which the Anthropocene can be defined micropalaeontologically. In order do this, microfloras and microfaunas (diatoms, macrophytes, dinoflagellate cysts, foraminifera ostracods) from nearshore waters through paralic freshwater aquatic milieux are considered, biotic variability with an causation identified....
ABSTRACT Species of the benthonic foraminiferal genus Bolivinoides provide a refined biostratigraphic biozonation for Late Campanian to Early Maastrichtian (Late Cretaceous) Shiranish Formation in NE Iraq. Three biozones and two subzones are identified: decoratus Biozone Campanian) subdivided into lower B. Subzone upper laevigatus Subzone; miliaris (Earliest Maastrichtian); draco (late Maastrichtian). These zones can be related biostratigraphical interval Globotruncana aegyptiaca Campanian),...
A San Francisco Estuary core was analysed at high resolution to assess its component stratigraphic signatures of the Anthropocene in form non-native species, Hg, spheroidal carbonaceous particles, δ 13 C org , 15 N, radiogenic materials, and heavy metals. Time series analysis using Ti data provides a chronology depth 167 cm into 1960s. Below this, 230 cm, lowermost part may extend 1950s or potentially little earlier. The earliest anthropogenic marker recorded is excursion Hg (beginning 190...
<strong class="journal-contentHeaderColor">Abstract.</strong> The Upper Cretaceous Kometan and Shiranish formations of the Kurdistan region, NE Iraq, yield diverse planktonic foraminiferal assemblages, with a total 93 species, which enable recognition nine biozones two subzones spanning early Turonian to late Maastrichtian. Sequential changes in assemblages map discrete intervals within that suggest dominantly warm, nutrient-poor marine surface near-surface conditions during mid-Turonian...
