Chronostratigraphy of Jerzmanowician. New data from Koziarnia Cave, Poland

Lincombian-Ranisian-Jerzmanowician (LRJ) sites are sparse, and Koziarnia Cave in Poland is one of only few such sites situated at the eastern fringe of LRJ. The aim of the recent study was to obtain new chronostratigraphic data for the LRJ industries due to their extreme scarcity in Central Europe. Although the new fieldworks did not bring new fossil directeur such as bifacial leafpoints, a detail debitage analysis enabled identifying a presence of the ventral thinning chips in layer D, which could be identified as the LRJ assemblage-containing stratum. Besides the LRJ assemblage, strata with traces of Late Middle Palaeolithic and Early Gravettian occupation were found at the site. The radiocarbon dates of Koziarnia samples show that the archaeological settlement represent one of the oldest Gravettian stays north to Carpathians. What is more, these dates demonstrate that the cave had been alternately occupied by humans and cave bears. Additionally the radiocarbon dates indicate rather young chronology of the Jerzmanowician occupation in Koziarnia Cave (c.a. 39-36 ky cal. BP). The results confirm the possibility of long chronology of the LRJ technocomplex, exceeding the Campanian Ignimbrite event.

Postclassic Tool Production at Santa Rita Corozal

This chapter presents a case study of a previously excavated lithic sample from Santa Rita Corozal, considering stone tool production at two structures, 216 and 218. Both exhibit a higher number of Postclassic chert and chalcedony lithic artifacts than other contemporary structures excavated at the site. The authors use debitage analysis to reveal how two households crafted formal tools locally and visual sourcing analysis to better understand how these tools articulated with broader traditions of lithic craft production in a regional exchange network. In contrast to the commercial level of production exhibited at Colha, Belize, these households used a variety of source materials and produced a less standardized tool kit on a much smaller scale.

Identifying Pre-Dorset structural features on southern Baffin Island: Challenges and considerations for alternative sampling methods

This paper describes an isolated Pre-Dorset component found at the Tungatsivvik (KkDo-3) site on southern Baffin Island. Micro-debitage analysis and systematic core sampling are proposed as a combined strategy to facilitate future investigations of Pre-Dorset occupations in this region.
