How did the Qesem Cave people use their teeth? Analysis of dental wear patterns


Sarig, Rachel; Gopher, Avi; Barkai, Ran; Rosell, Jordi; Blasco, Ruth; Weber, Gerhard W; Fornai, Cinzia; Sella-Tunis, Tatiana; Hershkovitz, Israel (2016). How did the Qesem Cave people use their teeth? Analysis of dental wear patterns. Quaternary International: The Journal of the International Union for Quaternary Research, 398:136-147.

Abstract

Dental wear pattern is an important source of information regarding dietary habits, food preparation, and human economic behavior. In the current study we present our preliminary analysis of the dental wear patterns of the Middle Pleistocene (420–200 kya) Qesem Cave teeth. Five types of tooth wear were studied: Occlusal wear, interproximal wear, subvertical grooves, buccal microwear and root striations. We found mild to moderate occlusal wear (stage range 2–4), the largest proximal facet on the M$_2$ medial was 15.3 mm$^2$, presence of three subvertical grooves on the M$_2$ distal surface, a variety of microwear scratches (many are >200 mμ long and >5 mμ wide) and two types of root striations. The data obtained suggests that the Qesem Cave people possessed a strong masticatory system producing massive anterior component of force, and used small flints as food choppers.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
