Arizona Bifaces of Wyoming Chert
KIVA, 1988ABSTRACTSeven bifaces from sites in Arizona and one from New Mexico are so similar in material, form, and workmanship that a single source is inferred. The distinctive raw material is tentatively identified as “Tiger Chert” from southwestern Wyoming. These finds suggest widespread exchange of large bifaces among the pueblos of the late thirteenth to ...

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

Face-regular bifaced polyhedra
Journal of Statistical Planning and Inference, 2001The authors consider polyhedra with two types of faces: \(p_a\) \(a\)-gons and \(p_b\) \(b\)-gons. Moreover, these polyhedra satisfy one of the following conditions: \(\bullet\) \(aR_i\): each \(a\)-gonal face is adjacent to \(i\) \(a\)-gonal faces; \(\bullet\) \(bR_j\): each \(b\)-gonal face is adjacent to \(j\) \(b\)-gonal faces. If the graph \(G_a\)

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 Acquisition of Biface Knapping Skill in the Acheulean
2018The Acheulean stone tools of Homo erectus and Homo heidelbergensis are the longest enduring of all archaeological cultures, lasting for 1.5 million years. Three competing hypotheses have been proposed to explain this longevity: that Acheulean technology lies in a zone of latent, easy to invent solutions to problems that H.

Inter-continental Variation in Acheulean Bifaces
2010This 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.

A Crescent Biface from Southeastern Utah
PaleoAmerica, 2020Crescent 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 ...

Effects of Raw Materials on Biface Manufacture
Science, 1979It 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.

Bifaces to the Ends of the Earth
2018The date of arrival of humans in the Americas is a long-standing puzzle in archaeology. A vein quartz biface from southern New England (South Hadley, Massachusetts) represents the oldest evidence for human occupation in New England, one of the last places in the United States to be colonized by Homo sapiens. The biface, which was resharpened and reused
