The Organization of Chipped-Stone Economies at Piedras Negras ...

domestic archaeological record at Piedras Negras suggests that they were not made there.
If the atlatl was used at Piedras Negras, the dart points probably were of laurel leaf form.
5.4.1.3.14: Small tanged uniface (see Figure 5.2 #35). One point of this type was found at
Piedras Negras. The specimen was made of a dark greenish flint. The blank was a
percussion blade, but it is unclear from what kind of blade core it was originally
removed. The term uniface is used loosely, once again, because both faces are partially
worked but with emphasis on one side. The piece is extremely light and could have been
used as a dart point. There also is an impact fracture at the tip of the point. Since the
material, blade technology, and tool morphology is unique at Piedras Negras, it is
assumed that the small tanged uniface was imported, and not made locally.
5.4.1.3.15: Small circular uniface (see Figure 5.2 #36; see Section 5.4.1.2.12 for
description).
5.4.2: Observations and Discussion
The microcrystalline-quartz tools described here represent many different forms
and reduction techniques, but in comparison with other sites from the lowlands, Piedras
Negras was rather conservative. This conservatism may be related to shared lithic
traditions with the Central Petén, as is evidenced by similarities in eccentric forms
between the two areas. Some forms appear to be relatively unique to Piedras Negras, such
as the medium oval uniface, but they are few. Other forms common throughout the Maya
