Description and taxonomic assessment of fossil Cercopithecidae from the Pliocene Galili Formation (Ethiopia)
Gona, Ethiopia
Central Andean (28–34°S) flood record 0–25 ka from Salinas del Bebedero, Argentina
The Salinas del Bebedero occupies an isolated basin in the foreland of central Argentina at 33°S and was flooded repeatedly over past 25 ka. Isotopic evidence demonstrates that this flooding was due to overflow of the nearby Río Desaguadero with waters derived from the distant (≥300 km) central Andes between 28–34°S. Stratigraphic and shoreline evidence shows that floods occurred most frequently from 14.3 to 11.4 ka, followed by lesser events bet…
The 6-Million-Year Record of Ecological and Environmental Change at Gona, Afar Region, Ethiopia
The rift setting of eastern Africa preserves exceptional records of mammalian (including hominin) fossils and archeology. The Afar region is host to multiple deposits with sediments ranging in age from>9 Ma to the present (Chorowicz, 2005; Katoh et al., 2016) and plays a major role in our understanding of human origins. The Gona project area contains fossiliferous deposits that span ca . 6.3 to <0.15 Ma (Quade et al., 2008); the duration of this …
Paleolithic Human Responses to Changing Aridity at Üçağızlı I cave, southern-coastal Turkey
Processes of Paleoindian site and desert pavement formation in the Atacama Desert, Chile
A distinct feature of many of the earliest archaeological sites (13,000-11,200 cal yr BP) at the core of the Atacama Desert is that they lie at or just below the surface, often encased in desert pavements. In this study, we compare these sites and undisturbed desert pavements to understand archaeological site formation and pavement development and recovery. Our results indicate these pavements and their soils are poorly developed regardless of th…
Multitechnique dating of earthen irrigation canals at the La Playa site, Sonora, Mexico
La Playa (SON:F:10:3) is an archaeological site in Sonora, Mexico that contains the remains of an extensive preceramic earthen irrigation canal system. Modern floodplain erosion has destroyed the majority of these canals, but geoarchaeological investigations on areas of the system that remain reveal much about this early agricultural technology. Comprehensive dating using accelerator mass spectrometry 14 C on gastropods, charcoal, and soil humate…
Fossil Cercopithecidae from the Early Pliocene Sagantole Formation at Gona, Ethiopia
Convergence of Evidence Supports a Chuska Mountains Origin for the Plaza Tree of Pueblo Bonito, Chaco Canyon
The iconic Plaza Tree of Pueblo Bonito is widely believed to have been a majestic pine standing in the west courtyard of the monumental great house during the peak of the Chaco Phenomenon (AD 850-1140). The ponderosa pine (Pinus ponderosa) log was discovered in 1924, and since then, it has been included in 'birth' and 'life' narratives of Pueblo Bonito, although these ideas have not been rigorously tested. We evaluate three potential growth origi…

Megalakes in the Sahara? A Review
The Sahara was wetter and greener during multiple interglacial periods of the Quaternary, when some have suggested it featured very large (mega) lakes, ranging in surface area from 30,000 to 350,000 km 2 . In this paper, we review the physical and biological evidence for these large lakes, especially during the African Humid Period (AHP) 11–5 ka. Megalake systems from around the world provide a checklist of diagnostic features, such as multiple w…
Megalakes in the Sahara? A Review – Addendum
A regional record of expanded Holocene wetlands and prehistoric human occupation from paleowetland deposits of the western Yarlung Tsangpo valley, southern Tibetan Plateau
The Asian Monsoon, which brings ~80% of annual precipitation to much of the Tibetan Plateau, provides runoff to major rivers across the Asian continent. Paleoclimate records indicate summer insolation and North Atlantic paleotemperature changes forced variations in monsoon rainfall through the Holocene, resulting in hydrologic and ecologic changes in plateau watersheds. We present a record of Holocene hydrologic variability in the Yarlung Tsangpo…
Isotopic Evidence for Long‐Distance Mammal Procurement, Chaco Canyon, New Mexico, USA
Previous research on the prehistoric communities of Chaco Canyon, New Mexico ( ca . A.D. 800–1250) provides evidence of an extensive procurement system of nonlocal food and economic goods. In this paper, we use oxygen and strontium isotope analyses to establish whether animal protein followed a similar pattern. We contextualized our isotopic analyses of the archaeofaunas from recent excavations at Pueblo Bonito with data on modern faunas across a…
Constraints on Paleoclimate from 11.5 to 5.0 ka from Shoreline dating and Hydrologic Budget Modeling of Baqan Tso, Southwestern Tibetan Plateau
14 C dating of shoreline deposits of closed-basin lake Baqan Tso in the western Tibetan Plateau shows that lake level regressed from the undated highstand (46 m above modern, 4.3 × modern surface area) of likely earliest Holocene age by 11.5 ka, and remained larger than modern until at least ≈ 5.0 ka. The shoreline record broadly matches other regional climate records, with lake level closely following Northern Hemisphere summer insolation overpr…
Lake Level Reconstruction for 12.8–2.3 ka of the Ngangla Ring Tso Closed-Basin Lake System, Southwest Tibetan Plateau
We present a shoreline-based, millennial-scale record of lake-level changes spanning 12.8–2.3 ka for a large closed-basin lake system on the southwestern Tibetan Plateau. Fifty-three radiocarbon and eight U–Th series ages of tufa and beach cement provide age control on paleoshorelines ringing the basin, supplemented by nineteen ages from shell and aquatic plant material from natural exposures generally recording lake regressions. Our results show…

A forager–herder trade-off, from broad-spectrum hunting to sheep management at Aşıklı Höyük, Turkey
Significance This article provides original results on the formative conditions of sheep domestication in the Near East. To our knowledge, none of the results has been published before, and the results are expected to be of wide interest to archaeologists, biologists, and other professionals interested in evolutionary and cultural processes of animal domestication.
Radiocarbon Dating, Mineralogy, and Isotopic Composition of Hackberry Endocarps from the Neolithic Site of Aşikli Höyük, Central Turkey
Carbonate is abundant in many Neolithic tells and is a potentially useful archive for dating and climate reconstruction. In this paper, we focus on the mineralogy, radiocarbon dating, and stable isotope systematics of carbonate in hackberry endocarps. Hackberry fruits and seeds are edible in fresh and stored forms, and they were consumed in large quantities in many Neolithic sites in the Near East, including the site of our study, Aşıkli Höyük in…

Radiocarbon Dating of Interdune Paleo‐Wetland Deposits to Constrain the Age of Mid‐to‐Late Holocene Microlithic Artifacts from the Zhongba site, Southwestern Qinghai‐Tibet Plateau
Microlithic artifacts, some found in situ , are abundant in the Z hongba archaeological site in southwestern T ibet. The site environment consists of extant wetlands and paleo‐wetland deposits found in depressions between sand dunes derived from the Yarlung Tsangpo floodplain. Constraining 14 C dates from wetland vegetation and shell from one site fall between ca . 6600–2600 cal. yr B.P., while a second site is dated 3400–1200 cal. yr B.P. A sign…
Compositional and Isotopic Analytical Methods in Archaeological Micromorphology
Resin‐impregnated sediment blocks are a by‐product of micromorphological sample processing. These blocks can be further studied using a variety of destructive, nondestructive, and minimally destructive geochemical techniques. X ‐ray fluorescence microanalyses conducted on sediment blocks yield semiquantitative major and trace elemental abundances that can be used to generate compositional maps, and to illustrate compositional change within or bet…

A Simplified In Situ Cosmogenic 14 C Extraction System
We describe the design, construction, and testing of a new, simplified in situ radiocarbon extraction system at the University of Arizona. Blank levels for the new system are low ((234 ± 11) x 10 3 atoms (1 σ; n = 7)) and stable. The precision of a given measurement depends on the concentration of 14 C, but is typically 3 atoms g –1 or more. The new system is relatively small and easy to construct, costs significantly less than the original in si…

Late Quaternary Environmental Changes in the Upper Las Vegas Valley, Nevada
Five stratigraphic units and five soils of late Pleistocene to Holocene age crop out in dissected badlands on Corn Creek Flat, 30 km northwest of Las Vegas, Nevada, and at Tule Springs, nearer to Las Vegas. The record is dominantly fluvial but contains evidence of several moister, marsh-forming periods: the oldest (Unit B) dates perhaps to the middle Wisconsin, and the more widespread Unit D falls between 30,000 and 15,000 yr B.P. Unit D therefor…
Late Wisconsin Groundwater Discharge Environments of the Southwestern Indian Springs Valley, Southern Nevada
Badland exposures in the Indian Springs Valley, southern Nevada, contain evidence of formerly widespread spring and seep discharge. The stratigraphic position and appearance of most of these deposits suggests correlation with late Wisconsin (30,000 to ca. 10,000 yr B.P.) marsh sediments in nearby Las Vegas Valley. Previously, all these deposits have been loosely described as lacustrine because of the presence of extensive green mudstones associat…

Reliable Late-Pleistocene Stratigraphic Ages and Shorter Groundwater Travel Times from 14 C in Fossil Snails from the Southern Great Basin
Both aquatic and land snails are common in the geologic record, but their utility in dating is greatly restricted by their well-documented tendency to yield 14 C dates inconsistent with true 14 C ages. In this study, we examine the use of 14 C ages from (1) small, previously unstudied, terrestrial snails to date hosting spring deposits and from (2) cooccuring aquatic snails to constrain groundwater travel times during the last glacial period. Our…

Late Pleistocene C 4 Plant Dominance and Summer Rainfall in the Southwestern United States from Isotopic Study of Herbivore Teeth
Patterns of climate and C 4 plant abundance in the southwestern United States during the last glaciation were evaluated from isotopic study of herbivore tooth enamel. Enamel δ 13 C values revealed a substantial eastward increase in C 4 plant consumption for Mammuthus spp., Bison spp., Equus spp., and Camelops spp. The δ 13 C values were greatest in Bison spp. (−6.9 to +1.7‰) and Mammuthus spp. (−9.0 to +0.3‰), and in some locales indicated C 4 -d…
Black Mats, Spring-Fed Streams, and Late-Glacial-Age Recharge in the Southern Great Basin
Black mats are prominent features of the late Pleistocene and Holocene stratigraphic record in the southern Great Basin. Faunal, geochemical, and sedimentological evidence shows that the black mats formed in several microenvironments related to spring discharge, ranging from wet meadows to shallow ponds. Small land snails such as Gastrocopta tappaniana and Vertigo berryi are the most common mollusk taxa present. Semiaquatic and aquatic taxa are l…
Fish Remains from Homestead Cave and Lake Levels of the Past 13,000 Years in the Bonneville Basin
A late Quaternary ichthyofauna from Homestead Cave, Utah, provides a new source of information on lake history in the Bonneville basin. The fish, represented by 11 freshwater species, were accumulated between ∼11,200 and ∼1000 14 C yr B.P. by scavenging owls. The 87 Sr/ 86 Sr ratio of Lake Bonneville varied with its elevation; 87 Sr/ 86 Sr values of fish from the lowest stratum of the cave suggest they grew in a lake near the terminal Pleistocene…
Holocene Lake-Level Fluctuations of Lake Aricota, Southern Peru
Lacustrine deposits exposed around Lake Aricota, Peru (17° 22′S), a 7.5-km 2 lake dammed by debris flows, provide a middle to late Holocene record of lake-level fluctuations. Chronological context for shoreline deposits was obtained from radiocarbon dating of vascular plant remains and other datable material with minimal 14 C reservoir effects ( 14 C yr B.P. and ended ∼2700 14 C yr B.P. Moderately high lake levels occurred at 1700 and 1300 14 C y…
Holocene Vegetation History from Fossil Rodent Middens near Arequipa, Peru
Rodent ( Abrocoma, Lagidium, Phyllotis ) middens collected from 2350 to 2750 m elevation near Arequipa, Peru (16°S), provide an ∼9600-yr vegetation history of the northern Atacama Desert, based on identification of >50 species of plant macrofossils. These midden floras show considerable stability throughout the Holocene, with slightly more mesophytic plant assemblages in the middle Holocene. Unlike the southwestern United States, rodent middens o…
Strontium isotopes reveal distant sources of architectural timber in Chaco Canyon, New Mexico
Between A.D. 900 and 1150, more than 200,000 conifer trees were used to build the prehistoric great houses of Chaco Canyon, New Mexico, in what is now a treeless landscape. More than one-fifth of these timbers were spruce ( Picea ) or fir ( Abies ) that were hand-carried from isolated mountaintops 75–100 km away. Because strontium from local dust, water, and underlying bedrock is incorporated by trees, specific logging sites can be identified by …

Paleowetlands and regional climate change in the central Atacama Desert, northern chile
Widespread, organic-rich diatomaceous deposits are evidence for formerly wetter times along the margins of the central Atacama Desert, one of the driest places on Earth today. We mapped and dated these paleowetland deposits at three presently waterless locations near Salar de Punta Negra (24.5°S) on the western slope of the Andes. Elevated groundwater levels supported phreatic discharge into wetlands during two periods: 15,900 to ~ 13,800 and 12,…
A Female Homo erectus Pelvis from Gona, Ethiopia
Analyses of the KNM-WT 15000 Homo erectus juvenile male partial skeleton from Kenya concluded that this species had a tall thin body shape due to specialized locomotor and climatic adaptations. Moreover, it was concluded that H. erectus pelves were obstetrically restricted to birthing a small-brained altricial neonate. Here we describe a nearly complete early Pleistocene adult female H. erectus pelvis from the Busidima Formation of Gona, Afar, Et…
