Migratory behavior in the enigmatic Late Pleistocene bovid Rusingoryx atopocranion
For many animals, migration is an important strategy for navigating seasonal bottlenecks in resource availability. In the savannas of eastern Africa, herds of grazing animals, including blue wildebeest ( Connochaetes taurinus ), Thomson's gazelle ( Eudorcas thomsonii ), and plains zebra ( Equus quagga ), travel hundreds of kilometers annually tracking suitable forage and water. However, we know nearly nothing about migration among the extinct spe…

Ecomorphology and ecology of the grassland specialist, Rusingoryx atopocranion (Artiodactyla
Rusingoryx atopocranion is an extinct alcelaphin bovid from the late Pleistocene of Kenya, known for its distinctive hollow nasal crest. A bonebed of R . atopocranion from the Lake Victoria Basin provides a unique opportunity to examine the nearly complete postcranial ecomorphology of an extinct species, and yields data that are important to studying paleoenvironments and human-environment interaction. With a comparative sample of extant African …
Human burials at the Kisese II rockshelter, Tanzania
OBJECTIVES: The Late Pleistocene and early Holocene in eastern Africa are associated with complex evolutionary and demographic processes that contributed to the population variability observed in the region today. However, there are relatively few human skeletal remains from this time period. Here we describe six individuals from the Kisese II rockshelter in Tanzania that were excavated in 1956, present a radiocarbon date for one of the individua…

Reconstruction of a semi-arid late Pleistocene paleocatena from the Lake Victoria region, Kenya
The effect of changing environment on the evolution of Homo sapiens is heavily debated, but few data are available from equatorial Africa prior to the last glacial maximum. The Karungu deposits on the northeast coast of Lake Victoria are ideal for paleoenvironmental reconstructions and are best studied at the Kisaaka site near Karunga in Kenya (94 to > 33 ka) where paleosols, fluvial deposits, tufa, and volcaniclastic deposits (tuffs) are exposed…
L’Aurignacien vu de l’Afrique
Le techno-complexe aurignacien en Eurasie, daté entre ~43-28 ka, ne connaît pas d’équivalent archéologique taxonomique en Afrique pour la même période, ce qui pourrait indiquer des différences liées à la communication intergroupes ou encore des différences découlant des définitions archéologiques actuellement employées. Des espèces d’hominidés disparues sont présentes en Eurasie et en Afrique pendant cette période, mais contrairement à l’Aurignac…
The Aurignacian Viewed from Africa
The Aurignacian technocomplex in Eurasia, dated to ~43-28 ka, has no direct archeological taxonomic equivalent in Africa during the same time interval, which may reflect differences in inter-group communication or differences in archeological definitions currently in use. Extinct hominin taxa are present in both Eurasia and Africa during this interval, but the African archeological record has played little role in discussions of the demographic e…
The Pleistocene prehistory of the Lake Victoria basin
Stable isotope paleoecology of Late Pleistocene Middle Stone Age humans from the Lake Victoria basin, Kenya
Paleoenvironmental context of the Middle Stone Age record from Karungu, Lake Victoria Basin, Kenya, and its implications for human and faunal dispersals in East Africa
Variability in the Middle Stone Age of Eastern Africa
Eastern Africa is an important area to study early populations of Homo sapiens because subsets of those populations likely dispersed to Eurasia and subsequently throughout the globe during the Upper Pleistocene. The Middle Stone Age (MSA) archaeology of this region, particularly aspects of stone-tool technology and typology, is highly variable with only rare cases of geographic and temporal patterning. Although there are differences in timing and…
The environmental context for the origins of modern human diversity
Late Pleistocene artefacts and fauna from Rusinga and Mfangano islands, Lake Victoria, Kenya
Surveys and excavations in 2009–2011 recovered fossil and artefact assemblages from late Pleistocene sediments on Rusinga and Mfangano islands (Lake Victoria, Kenya). Radiometric age estimates suggest that the Rusinga material dates to between 100 and 33 kya, whereas that from Mfangano may date to ≥35 kya. The preservation of a large and diverse suite of vertebrate fossils is unusual for Pleistocene sites in the Lake Victoria region and the compo…
Taxonomic status and paleoecology of Rusingoryx atopocranion (Mammalia, Artiodactyla), an extinct Pleistocene bovid from Rusinga Island, Kenya
Rusingoryx atopocranion is a poorly known extinct alcelaphine bovid, documented in Pleistocene deposits associated with Middle Stone Age artifacts on Rusinga Island, Kenya. Following its initial description, Rusingoryx was subsumed into Megalotragus , which includes the extinct giant wildebeests, on the basis of its cranial architecture. Renewed investigations of the Pleistocene deposits on Rusinga Island recovered a large sample of Rusingoryx sp…

Tephrostratigraphy and the Acheulian to Middle Stone Age transition in the Kapthurin Formation, Kenya
"Early" Middle Stone Age Lithic Technology of the Kapthurin Formation (Kenya)
The production of Levallois flakes is considered a hallmark of many Middle Stone Age (MSA) sites, but this aspect of African Pleistocene hominin technology remains poorly documented relative to that from adjacent regions. The site of Koimilot, from the Kapthurin Formation of Kenya, preserves stratified artifact assemblages that show use of multiple Levallois methods to produce flakes of varied shapes and sizes, comparable to that described from L…

Tephrostratigraphy and the Acheulian to Middle Stone Age transition in the Kapthurin Formation, Kenya
Tephrostratigraphy of the Bedded Tuff Member (Kapthurin Formation, Kenya) and the nature of archaeological change in the later middle Pleistocene
Correlation of volcaniclastic deposits of the Bedded Tuff Member (K4) of the Kapthurin Formation (Kenya) provides the means to assess the nature of archaeological change during the later middle Pleistocene, a time period critical to human evolution but poorly represented at other African localities. Field stratigraphic evidence, and petrographic and electron microprobe geochemical analyses of volcanic glass and phenocrysts, define eight subdivisi…
The Destructive Potential of Earthworms on the Archaeobotanical Record
Earthworms are widely recognized as important agents in the formation, preservation, and alteration of archaeological sites. I conducted experiments that test the ability of earthworms (Lumbricus rubellus) to ingest and subsequently destroy carbonized seeds (Tapaver somniferum) under controlled settings, designed to reflect field conditions during feeding or burrowing. Results suggest modest seed breakage rates at short time scales that may resul…
