Reconstructing the late pleistocene palaeoenvironment of the Richtersveld using fossil charcoal
… the Richtersveld have provided a rare source of palaeoenvironmental data in the form of fossil wood charcoal assemblages that span a sequence from the last glacial maximum (LGM) to ~14 500 yrs BP. The present study analysed the fossil charcoal deposits from the rockshelter in order to reconstruct …

Unravelling the impacts of palaeoecology, palaeoenvironment and lithofacies on sedimentary organic NSO compounds
… well suited to record precursor biotic and palaeoenvironmental signatures. In addition, their physical properties are such that they possess the capacity to interact specifically with minerals of distinct surface chemistry, so they can provide precise indications for elucidating …

Stratigraphy and Palaeoenvironment of the Paleocene/Eocene boundary interval in the Indus Basin, Pakistan
Marine sedimentary sections across the Paleocene/Eocene (P/E) boundary interval are preserved in the Patala Formation (Upper Indus Basin) and Dungan Formation (Lower Indus Basin), Pakistan. The P/E interval of the Patala Formation is composed of limestone and shale inter-beds indicating deposition …

Scourge or Sustenance: Using microfauna to explore the palaeoenvironment and palaeoeconomics of Epipalaeolithic and early Neolithic communities in Anatolia.
… were analysed in order to: reconstruct the palaeoenvironment; identify whether microfauna were used as part of a broad-spectrum economy; determine if anthrodependent species such as the house mouse were present at either Boncuklu or Pınarbaşı indicating sedentism, and to establish if any of …

New research methods for the analysis of fossil Anura ilia and their utility for reconstructing the palaeoenvironment of Swartkrans Cave
Anura fossils are relatively common amongst microfauna assemblages but remain largely unanalysed because of a lack of expertise. This is unfortunate since Anura are effective indicators of environmental conditions as their life cycles and breeding patterns are integrally linked with temperature and …

4000 years of environmental and climate change at Eilandvlei : a palynological investigation into the late Holocene palaeoenvironment of the Wilderness Embayment
It is a well-known fact that the South African palaeoenvironmental record is fairly limited, mainly because the environmental conditions here do not lend themselves to the preservation of proxy data sources. This being said, new evidence is emerging from the Wilderness Embayment along the Southern …

Investigation the use of oxygen and carbon isotopes and sclerochronology on Turbo sarmaticus and Donax serra for palaeoenvironment reconstruction at Pinnacle Point, South Africa
This thesis investigates the validity of oxygen isotope analysis for the gastropod Turbo sarmaticus (operculum and shell) and the bivalve Donax serra to reconstruct sea surface temperatures. These are the species most commonly retrieved from archaeological assemblages of the South Coast of South …

Palaeoenvironmental reconstruction and geoarchaeology of the Cuatro Cienegas Basin, NE Mexico, from the late Pleistocene to the present
… studied area in terms of conservation. The palaeoenvironment, however, is relatively understudied with only two reconstructions published to date - Meyer [1973] and Minckley and Jackson [2008]. This project has analysed a 15 m carbonate sediment core for multi-proxy palaeoenvironmental …

Archaeology and environment in the vale of York
… deposition and evidence for mode of origin and palaeoenvironment is discussed, with particular regard to insect faunas from within the Sands at Flixborough and Messingham, near Scunthorpe. A brief examination of the nebulous Creswellian industry in relation to the Sands is followed by the study …

Stable isotope analysis of fauna and soils from sites in the Eastern Free State and Western Lesotho, Southern Africa : a palaeoenvironmental interpretation
… carbon isotopes as a means of reconstructing the palaeoenvironment of the Caledon River Valley of the eastern Free State, South Africa, and western Lesotho. In doing so, this work draws upon previous studies that have shown that the distinct distribution and δ¹³C values of C₃ and C₄ grasses are …

Architecture and origin of fluvial cross-bedding based on flume experiments and geological examples field case studies: Rillo de Gallo, Spain and Northumberland, UK
… diagnostic of flow pattern, and should improve palaeoenvironment interpretation. A relationship between the amount of variation in bar lee-face angle with bar height was found in the flume and may be useful for inferring bedform size in the rock record. Integration of laboratory and field …

Neanderthal and Modern Human Adaptations to Climate Change in Southwest Asia: Climate Reconstruction of Marine Isotope Stage 5 to 3 based on small mammal records from Shanidar Cave (Iraqi Kurdistan)
Understanding the link between environmental and climatic fluctuations and changes in hominin populations and their distribution is one of the major challenges facing archaeologists and palaeoanthropologists. One notable key demographic event is the expansion of Homo sapiens (‘Modern Humans’) and …
