Late Pleistocene Sciurids from Kokoweef Cave
… Spermophilus townsendii, and Spermophilus lateralis) sciurid species (Sciuridae) were identified from the late Pleistocene-early Holocene Kokoweef Cave paleofauna. This fauna was the first documentation of T. minimus, T. palmeri and S. townsendii from the Pleistocene of the Mohave Desert. …

Assessing Holocene and late Pleistocene geomagnetic dipole field variability
… The dipole tilt reconstruction is highly correlated to millennial scale variations in the length of day, reconstructed from ancient records of eclipses, which suggests that the 1350-year cyclicity may constitute an important component of core flow dynamics.

Reconstructing the late pleistocene palaeoenvironment of the Richtersveld using fossil charcoal
… biome are thought to have originated during the Pleistocene epoch. However, due to the paucity of palaeobiological proxy data available for the Succulent Karoo, relatively little is known about its environmental history and how an important core of this region, Namaqualand and its subregion the …

Late Pleistocene Stratigraphy And Events In The Asbestos-valcourt Region, Southeastern Quebec
… at least two regional glacial advances underlie Late Wisconsinan ice-contact and glaciolacustrine sediments. Glaciolacustrine sediments (unit B), which underlie surface till (drift unit C), were deposited during a rather short-lived interstade, prior to the Late Wisconsinan glacial maximum; unit …

Climate, environment, and competition influenced human land preference in late pleistocene Australasia
… models. Here, for the first time, we calculate fossil estimates of human-carnivore competition (competition index) from five Late Pleistocene sites in Laos and Vietnam to be included in ENM analyses of human land preference. We also take traditionally used environmental predictors and apply …

Stratigraphy and Depositional Environments of a Late Pleistocene Barrier Island Complex, Southeastern Virginia
<p>The Norfolk, Kempsville, and Sand Bridge Formations beneath the HIckory Scarp of southeastern Virginia are reinterpreted as representing one glacio-eustatic transgressive cycle. The timing of this transgressive event is set during the earliest Wisconsinan. The formations were previously …

Late Pleistocene and Holocene geology of the Moe Site, New Town, North Dakota
Eight stratigraphic units of Late Cenoioic age are present around the Moe Archeological Site near New Town, North Dakota. Unit Zero is a layer of glacial sediment consisting of grayish brown pebbly clay loam. Unit One consists of fluvial and beach sand and gravel. Unit Two consists of light …

Sedimentological analyses of late Pleistocene sediments from Lake Lisan in the Jordan River Valley, Israel
… were formed in the hypersaline Lake Lisan, the Pleistocene precursor of the Dead Sea, sometime between 31,000 and 19,000 years ago. Abundant calcite and shells of the brackish water ostracod Cyprideis torosa in the sediments, as well as additional shells of species such as Humphcypris …

Ocean circulation and carbon cycle dynamics in the Pacific Southern Ocean during Late Pleistocene interglacials
… as the West Antarctic Ice Sheet stability during Pleistocene interglacial periods that are often considered analogs for the current interglacial period. Applying a multi-proxy approach, this thesis investigates CDW upwelling dynamics using planktic and benthic foraminiferal δ13C, bottom water …

Evaluating Late Pleistocene and Holocene Rupture, Seismic Hazards and Ground Motion in the Lake Tahoe Basin

Luminescence based chronologies on Late Pleistocene loess-palaeosol sequences: an applied-methodological study on quartz separates
… Luminescence dating, especially optically stimulated luminescence (OSL), is the leading dating approach for establishing chronologies on loess archives. Furthermore, the development of luminescence dating techniques on sediments is closely connected with the history of loess research and vice …

Palaeoenvironmental and palaeogeographic reconstruction of the Tequixquiac Basin, Central Eastern Mexico: Mid to late Pleistocene environments
… the first time, sedimentary evidence for mid to late Quaternary environmental change in the Tequixquiac region of Central-eastern Mexico. This project has logged over 50 stratigraphic sections and geochemically analysed a 55 m lithostratigraphic sequence for multi-proxy palaeoenvironmental …

Late Pleistocene lithofacies, paleolimnology and ostracode fauna of kettles on the Illinoian till plain, Illinois, U.S.A
The response of sediment, vegetation and aquatic environments to climate change during the last glacial--interglacial--glacial intervals were investigated from fossiliferous successions in four breached kettle basins in south-central Illinois. The thickest measured successions of lacustrine/paludal …

Stable Isotope Sclerochronology of Melanopsis (Gastropoda) Shells: Inferring Late Pleistocene Seasonality in the Upper Jordan River Valley
Sub-weekly to sub-monthly records of δ 18 O and δ 13 C values in Melanopsis shells from the Jordan River Dureijat (JRD) archaeological site in the upper Jordan River Valley are assessed for changes in seasonal hydrology in the gastropod’s habitat, and these records are compared to results from one …

Geochemistry of karst deposits in Borneo detailing hydroclimate variations in the Warm Pool across the late Pleistocene
… U/Th-dated and continuous throughout most of the late Pleistocene (0-160 thousand years ago, kybp). The record comprises an entire glacial-interglacial cycle, which allows us to investigate orbital-scale climate forcings and compare two well-dated glacial terminations in the western tropical …
