A Crescent Biface from Southeastern Utah

PaleoAmerica, 2020
Crescent bifaces are one of the most enigmatic stone tool types in North America. While these artifacts are poorly understood, they are widely known from sites throughout a core area consisting of ...

Inter-continental Variation in Acheulean Bifaces

2010
This chapter uses euclidean distance measurements of biface length, width and thickness to assess inter-continental variability in Acheulean biface morphology. Assemblages from eastern Asia and the Arabian peninsula are tested for their similarity to Acheulean assemblages in eastern Africa and the Indian sub-continent.

Bifaces as Knives

2002
As Curry, O’Brian, and Timble (1985) noted in their discussion of hafted bifaces, not all projectile points were used in projectiling. As an argument and explanation, the Native American projectile point has other functions, namely the knife function. This function for a projectile point dates to the Clovis point and continues to the post-Contact era.

The Westfahl and Engle Bifaces: Isolated Finds of Large Bifaces on the Southern Plains

Plains Anthropologist, 1996
La decouverte en surface de deux grands bifaces a l'ouest de l'Oklahoma souleve un certain nombre de questions quant a leur fonction et leur affiliation culturelle. Tout deux sont tailles dans un silex du centre-ouest du Texas. L'etude de leurs attributs technologiques fournit des indices permettant de les relier aux groupes paleoindiens et archaiques ...

Edge Abrasion during Biface Manufacture

American Antiquity, 1973
AbstractNance intended to demonstrate that certain small, bifacially chipped obsidian artifacts from the California Late horizon were used for cutting purposes, and were therefore not projectile points. However, both categories of edge abrasion noted by Nance, attrition and striation, may also appear on the edges of bifacially flaked artifacts during ...

Effects of Raw Materials on Biface Manufacture

Science, 1979
It has been suggested that the degree of refinement of trimming seen on Lower Paleolithic bifaces reflects the level of technical sophistication of the toolmaker. This has been tested by a series of experiments carried out at Olduvai Gorge, Tanzania, and related to some of the archeological assemblages there.

The Three Sides of a Biface

American Antiquity, 1988
Three different sorts of bifacial tools-by-products of the shaping process, cores, and long use-life tools-are used to consider the role mobility plays in producing variability in hunter-gatherer lithic technologies. The relations among tool roles, raw-material distribution, and mobility as well as the archaeological consequences of the different roles
