BackgroundIn recent years the Later Stone Age has been redated to a much deeper time depth than previously thought. At the same time, human remains from this time period are scarce in Africa, and even rarer in West Africa. The Iwo Eleru burial is one of the few human skeletal remains associated with Later Stone Age artifacts in that region with a proposed Pleistocene date. We undertook a morphometric reanalysis of this cranium in order to better assess its affinities. We also conducted Uranium-series dating to re-evaluate its chronology.Methodology/Principal FindingsA 3-D geometric morphometric analysis of cranial landmarks and semilandmarks was conducted using a large comparative fossil and modern human sample. The measurements were collected in the form of three dimensional coordinates and processed using Generalized Procrustes Analysis. Principal components, canonical variates, Mahalanobis D2 and Procrustes distance analyses were performed. The results were further visualized by comparing specimen and mean configurations. Results point to a morphological similarity with late archaic African specimens dating to the Late Pleistocene. A long bone cortical fragment was made available for U-series analysis in order to re-date the specimen. The results (∼11.7–16.3 ka) support a terminal Pleistocene chronology for the Iwo Eleru burial as was also suggested by the original radiocarbon dating results and by stratigraphic evidence.Conclusions/SignificanceOur findings are in accordance with suggestions of deep population substructure in Africa and a complex evolutionary process for the origin of modern humans. They further highlight the dearth of hominin finds from West Africa, and underscore our real lack of knowledge of human evolution in that region.
The Ciuntu rockshelter is situated in the north-western part of the Republic of Moldova, on the left bank of the river Pruth. It has a single Upper Palaeolithic layer of occupation, which was originally regarded as Early Upper Palaeolithic and was assigned to the Brinzeni archaeological culture. More recent investigations, including radiocarbon dating, have led to a revision of this suggested age and classification. The site is now regarded as belonging to the Middle Gravettian and is dated to the beginning of the last glacial maximum.
The first inhabitants of Jamaica are now generally referred to as Taínos. It is likely that they arrived in the island after about 650 AD and were extinct by the end of the 16 th century. In 1968, during the exploration of a small cave in Bull Savannah, St. Elizabeth parish, Dr. James Lee found two skulls, teeth, bones, and pottery. The aim of this work is to interpret in a biocultural perspective the one cranium with pathological lesions, such as caries sicca. This adult individual had an artificially modified cranium, a cultural practice common among Taínos, which was studied macroscopically and by radiological and computerized tomography. The radiocarbon dates, obtained by AMS, point to the 10 th-11 th centuries AD and the stable isotopes analysis revealed either the ingestion of a mixed C3/C4 plant diet or an extensive intake of marine resources, the former being more likely. This is the first cranium to be found in Jamaica with evidence of Pre-Columbian treponematosis, most probably syphilis, which has also been demonstrated in a few cases elsewhere in the Caribbean region. This finding agrees with the ethnohistorical narrative, according to which syphilis existed among the native population, who used plant extracts to treat the disease. This paper contributes to our knowledge about the Taínos and the history of treponematosis in the Americas.
Brînzeni cave occupies an important place in the Palaeolithic of Moldova. Its significance is reconsidered in the light of work carried out at the site in 1992–1993 and subsequently, and the opportunity is taken to bring together both published and previously unpublished reports about it, to shed light on its environmental history and archaeological characterisation. On current evidence, the principal occupation layer occupies a chronologically intermediate position between the Aurignacian and the Gravettian in the region, and the archaeological assemblage is certainly distinctive, although probably not ‘transitional’ in the sense previously claimed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
