La Ferrassie (France) Discovery of New Deposits

In 2010, we began new excavations at the classic Mousterian site of La Ferrassie. One of the main results of this project is the discovery of new, in situ deposits in the western portion of the site. These deposits are now the focus of excavation to better understand the site formation and how it relates to the proported burials, the chronology, and the industries.

Abri Peyrony (France) Late Mousterian Adaptations

In 2009, we re-opened the MTA site of Abri Peryony (part of the Combe-Capelle complex of sites). The site is situated at the base of a low cliff and contains only two levels of MTA. Faunal preservation is good, and along with Pech I, Pech IV and Jonzac, it brings further data on late Neandertal adapations. Excavations finished in 2012.

Contrebandiers (Morocco) Aterian Coastal Adapations

From 2007 to 2011, we excavated the Aterian and so-called Mousterian site of La Grotte des Contrebandiers on the Moroccan coast just south of Rabat. This cave site yielded new human remains that are currently under study along with lithic and faunal assemblages. Some results have now been published.

About OSA

OSA represents a diverse group of researchers who have been working together for a number of years mainly on Neandertal sites in southwest France but also on penicontemporaneous sites in north Africa (Morocco and Egypt) and in east Africa (Ethiopia). Broadly our goal has been to better understand the evolution of hominin behavior through the excavation of archaeological sites using a comparable set of standards and methodologies. This work has resulted in a data set coming from ten sites (caves, rockshelters, and open-air) and over 140 different stratigraphic contexts. New excavations by students who trained with us are expanding this data set still further.

On this web site we also host pages put together by Anta Montet-White to published additional data from her excavations in France and Bosnia. If you have Paleolithic material that you would like to host here, please contact us.

Methods, Data, and Other Resources

Over the years we have emphasized the use of technology to make excavation and analysis more efficient and effective. We have published many of these efforts, and we have shared our software freely in part to encourage the development of standards.

Several data sets from excavations that are finished and published are available here (including data from Montet-White's excavations). When we finish the publication of Pech de L'Aze IV, it will be the next database to go on-line.
