Computer-Assisted Morphometry: A New Method for Assessing and Distinguishing Morphological Variation in Wild and Domestic Seed Populations

A Clovis well at the type site 11,500 B.C.: The oldest prehistoric well in America
An enigmatic circular pit uncovered during archaeological excavations at the Clovis type site, Blackwater Draw, New Mexico, in 1964 has been reexposed and posited as a water well excavated by Clovis people around 11,500 B.C. The prehistoric well, the oldest in the New World, was probably a dry hole. Other Clovis wells may exist in the area. The excavation of wells near where there had been surface water shortly before adds to the evidence for dro…

Extraction of Opal Phytoliths from Herbivore Dental Calculus
Stereological Identification of Opal Phytolith Populations from Wild and Cultivated Zea
Reported criteria for distinguishing wild Zea varieties (teosinte) from cultivated primative maize using plant opal phytolith morphology were tested using computer-assisted image analysis. Results showed current criteria to be effective but inconsistent. A straightforward stereological algorithm was derived from image analysis data providing high-confidence statistical assignment of the Zea phytolith populations in this study to wild or cultivate…
Phytolith Analysis: An Archaeological and Geological Perspective
Macro‐ and micro‐ecological reconstruction using plant opal phytolith data from archaeological sediments
Phytolith analysis is rapidly maturing into a robust and powerful paleobotanical data system. Many plant groups can be identified to family or subfamily, and even species identification has been suggested. Distinctive phytoliths occur abundantly in members of the grass family and are also found in several other groups including rushes, sedges, palms, conifers, deciduous trees, and other dicotyledonous plant taxa. Soil phytolith assemblages have p…
Comment on Bray's “An Eighteenth Century Reference to a Fluted Point from Guatemala”
Bray's interpretation of an eighteenth century reference to a lithic implement in Guatemala as describing a fluted projectile point is challenged on the grounds that semantic variations of the translation may well fit the attributes of a late period-style obsidian prismatic blade. Problems in distinguishing between genuinely fluted points and "pseudofluted" points are also noted. The possibility of widespread pseudofluted points in Central and So…

Note on a Safer Procedure for Opal Phytolith Extraction
Potential of Opal Phytoliths for use in Paleoecological Reconstruction
Opal phytoliths, inorganic biogenetic plant particles of microscopic size, were investigated to determine the level at which their varied morphology is taxonomically significant. Extraction methods for the isolation of these particles from living plants and from soils were developed to provide maximum preservation of morphological features while remaining simple, rapid, and inexpensive. Extracts were made and microscopically viewed from 30 live s…
Preliminary Report of a Stratified Post-Folsom Sequence at Blackwater Draw Locality No. 1
Little is known of the post-Folsom sequence at Blackwater Draw, Locality No. 1, in spite of over 30 years of intermittent excavation by major institutions at this site location. Until recently it has been lumped under the name of the 'Portales complex' under which several culture complexes were grouped as a single entity. This paper makes an initial attempt to separate these cultures in chronological sequence
