Abstract The drivers of the global Quaternary megafaunal extinction are constantly being updated and discussed. Most paleoarchaeological sites in South America with proboscideans and humans in association are considered as clear killing sites, an interpretation that might not consider their taphonomic aspects and neglect other ecological interactions. Here we describe a unique example of megafaunal killing by humans in South American, a skull of a young Notiomastodon platensis from Brazil with a...
Abstract The Torca del Leon site (Asturias, NW Spain), discovered in 2014, provided an interesting fossil assemblage including a P. spelaea partial skeleton and a rich micro-mammal community with palaeoenvironmental significance. The bone accumulation was formed in a karstic cave that acted as a natural trap, as indicated by the geomorphology of the cavity (connected to a 16 m deep shaft) and the lack of signs of human or carnivore activity on the bones. The large-mammal assemblage is composed o...
Abstract Reconstruction of Paleomagnetic Secular Variation (PSV) of the geomagnetic field is fundamental both to assess geodynamo models and to obtain age constraints for rocks, sediments and archaeological material. We present refined age-calibrated Holocene PSV and relative paleointensity (RPI) stack curves derived from Arctic marine sediments (Northwestern Barents Sea). The Holocene sections of four sedimentary cores were correlated on the basis of paleomagnetic trends and age models, and sta...
Abstract Based on data from analyses on previously-reported carbon stable isotope data from dental enamel and dentine from tusks reported in the literature, diets were inferred for the gomphothere genera Amebelodon, Cuvieronius, Gomphotherium, Rhynchotherium, Serbelodon, and Stegomastodon (Proboscidea, Gomphotheriidae) that inhabited the Americas during the Cenozoic. Amebelodon, Gomphotherium, and Serbelodon specimens of the Barstovian and Clarendonian faunal stages fed on C3 plants; while the s...
Abstract During the Late Glacial, hunter-gatherers began using ceramic cooking containers in three separate geographic regions of East Asia: China, Japan and in the Russian Far East. While recent research has clarified the use of early pottery in Japan, very little is known about what led to the emergence of pottery in the other two areas, including the likely environmental, economic or cultural drivers. In this paper we focus on a series of key sites along the Amur River in the Russian Far East...
Abstract Past climates and environments experienced by the Saharo-Arabian desert belt are of prime importance for palaeoclimatic and palaeoanthropological research. On orbital timescales transformations of the desert into a grassland landscape in response to higher precipitation provided “windows of opportunity” for hominin dispersal from Africa into Eurasia. On long timescales, palaeoenvironmental reconstructions for the region are predominantly derived from marine sediments and available terre...
Abstract Climate variability and its forcings in eastern South Africa during the late Quaternary remain poorly understood with data suggesting temporal variability and spatial heterogeneity. To constrain the variability and the drivers of past climate, we explore vegetation (C3/C4) and hydrological change using stable carbon and hydrogen isotopes of plant-waxes and X-ray fluorescence (XRF) analysis in marine core GeoB20610-2 offshore the Limpopo River. We find evidence for two climatic phases: a...
Abstract Here we present an integrated earth surface process and paleoenvironmental study from the Tingri graben and the archaeological site of Su-re, located on the southern rim of the Tibetan plateau, spanning the past ca. 30 ka. The study area is characterized by cold climate earth surface processes and aridity due to its altitude and location in the rain shadow of the Mount Everest–Cho Oyu massif and is thus sensitive to climatic and anthropogenic perturbations. In this highly dynamic geomor...
Abstract Sequences of uplifted marine terraces are widespread and reflect the interaction between climatic and tectonic processes at multiple scales, yet their analysis is typically biased by the chosen sea-level (SL) curve. Here we explore the influence of Quaternary SL curves on the geometry of marine terrace sequences using landscape evolution models (LEMs). First, we modeled the young, rapidly uplifting sequence at Xylokastro (Corinth Rift;
Abstract This paper presents a reappraisal of evolution in the extinct Pleistocene straight-tusked elephant Palaeoloxodon, based on cranial morphology. Particular emphasis is given to the parieto-occipital crest (POC), a specialised structure of the Palaeoloxodon skull. A key aim of this contribution is to discuss the systematic significance of the so-called “Stuttgart” and “namadicus” cranial morphs among Eurasian Palaeoloxodon. Materials examined and discussed mostly represent large-sized cont...
