Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Palynofacies, palaeoenvironments and petroleum [PDF]

Journal of Micropalaeontology, 1982
Abstract. During the past decade, transmitted light microscopy of dispersed organic particles has become an important tool for assessing the petroleum potential of sedimentary basins. The main components of palynofacies and the colours of the microfossils preserved therein are widely used in the oil industry to aid the determination of organic ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Magura Cave, Bulgaria: A multidisciplinary study of Late Pleistocene human palaeoenvironment in the Balkans [PDF]

, 2016
Two trenches excavated at Magura Cave, north-west Bulgaria, have provided Late Pleistocene lithic artefacts as well as environmental evidence in the form of large and small mammals, herpetofauna and pollen recovered from Crocuta coprolites.

Aux origines africaines de l’homme

Afrique Archéologie Arts, 2010
During the past decade, the palaeontological history of man has been considerably enriched by the discovery of several potential ancestors of humans, gorillas and chimpanzees in Africa allowing a better reconstruction of our phylogenetic tree (even ...

Pleistocene glaciation of Fenland, England, and its implications for evolution of the region [PDF]

Royal Society Open Science, 2018
Detailed investigation of landforms and their underlying deposits on the eastern margin of Fenland, East Anglia, demonstrated that they represent a series of glaciofluvial delta-fan and related sediments.

70 years later – New research at Holley Shelter, a Middle and Later Stone Age site in KwaZulu-Natal, South Africa

South African Journal of Science, 2022
In 1952, Gordon Cramb published the first report on his excavations at Holley Shelter, in KwaZulu-Natal, South Africa. Although Cramb’s work implied organic preservation associated with a unique stone tool assemblage from a Middle Stone Age (MSA ...

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...
