Africa: Northern Africa (Geographic Keyword)
1-7 (7 Records)
Earth system models are climate models capable of simulating land-atmosphere feedbacks and the complex biogeochemical and biogeophysical processes that drive them. These models are particularly well-suited to studying the impact of preindustrial land use on regional climate change, as they explicitly resolve the impacts of irrigation, deforestation, and agropastoral production on the flow of water and energy between the land and atmosphere. Generating realistic maps of past land use is a...
The Middle Stone Age Record in Egypt and Sudan: Implications for Out of Africa 2 (2019)
This is an abstract from the "Recent Advances and Debates in the Pleistocene Archaeology of Africa" session, at the 84th annual meeting of the Society for American Archaeology. Africa is the continent of origin for Homo sapiens and thus is the source for human colonization of the Old (and eventually New) World. Out of Africa 2 (anatomically, then behaviorally, modern humans) is supported archaeologically by African stone artifact industries found outside of Africa. Two routes widely...
Multi-isotopic Investigation of Late Pleistocene Human Diet from the Site of Taforalt, Morocco (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. The Paleolithic to Neolithic transition generally denotes a dietary change from hunting, gathering, and fishing to agriculture. However, due to the limited number of Pleistocene sites that have yielded preserved human remains, our knowledge of the diets of pre-agriculturist human populations is still limited. Previously published isotopic studies have...
Preliminary Results of Ground Penetrating Radar (GPR) Geophysical Prospection at the Neo-Punic/Roman Period Site of Zita, Tunisia (2018)
During the summer of 2016, preliminary geophysical prospection survey using ground penetrating radar (GPR) was conducted at the Neo-Punic and Roman period site of Zita, Tunisia. Since the time available for the fieldwork was limited to two weeks, the survey focused on examining specific areas of the site to document certain architectural features, and in several locations where industrial activities were known to have occurred based on previous limited excavations. Additionally, a region...
Radiocarbon Dating of Land Snail Shell and the Chronology of MSA-Neolithic Human Activity in the Haua Fteah, Libya (2018)
Land snails have a radiocarbon ecology which leads to offsets in shell radiocarbon age, relative to contemporary biogenic carbon. We describe new methods for evaluating and calculating this offset. We radiocarbon date and apply the new methods to land snail food debris, from the deep MSA to Neolithic sequence in the Haua Fteah cave, NE Libya. Oxcal modelling of the resulting 136 dates over ~45000 years shows the site was used for short episodes separated by long periods of abandonment. The...
Roman Amphoras of North Africa: Markers of a Pan-Mediterranean Economy (2018)
This project is centered around the Roman amphorae excavated from the Palatine East Archaeological Project. The site is located on the northeast slope of the Palatine Hill in Rome. The ceramic deposits date from the first century to about the fifth of sixth century CE. I focus on the amphorae produced in North African, specifically those of Tunisian origin. My work is hoping to better understand the geographical location of production sites of these trade vessels. The results of this project...
Which Way Did They Go? Using Individual-Based Models to Identify Out of Africa Hominin Dispersal Routes (2018)
There is a broad paleoanthropological consensus that hominins left Africa multiple times during the Pleistocene, but the geographic routes through which they exited the continent remains unclear. Although the Sinai Land Bridge and the Strait of Bab-al-Mandab on the southern end of the Red Sea are commonly implicated as the likely pathways used by early humans during their expansion out of Africa, the evidence supporting each route is still much debated. Here, we identify viable pathways for...
