Heather Pringle (Special Section, Archaeology, 20 Nov. p. (1446)(1)) cites recent plant opal phytolith research by Dolores Piperno and Deborah Pearsall bearing on the question of agricultural origins in South America. Those of us with long experience in the development of phytolith analysis are convinced it has enormous potential, especially in such areas as archaeobotanical research.
In paleoecology, the unit of analysis and interpretation and the basis for intra- and interregional comparisons of the phytolith record is the phytolith assemblage. This chapter discusses method and theory regarding the interpretation of phytolith assemblages. It is the tabulation and quantification in percentages, absolute numbers, or ratios of all morphological variants observed in a sample.
Phytolith analysis is a micro-botanical technique used in archaeology to study ancient plant remains. Phytoliths are opaline silica bodies formed during the lifetime of a wide variety of plant taxa within and between certain cells. These micro-remains can provide insight into ancient diet, the non-food uses of plants (such as for fuel or weaving), spatial arrangements of plant use and discard.
For example, where pollen analysis is weak, as in the recognition of herbaceous and arboreal taxa of mature tropical rain forest, phytolith analysis provides significant information (Piperno, 1993). Conversely, in the recognition of woody, secondary tropical forest growth where phytolith analysis may be “silent”, pollen data come to the rescue. Phytolith studies have also significantly.Learn More

Dr. Dolores Piperno, Curator of Archaeobotany and South American Archaeology, is an archaeologist and archaeobotanist. Her research focuses on the antiquity and character of prehistoric human adaptations in the lowland tropical regions of the world, including agricultural orgins, together with the biogeographical and climatological history of the tropical biome.Learn More
Phytolith is the combination of two Greek terms - “plant” (phyto) “stone” (lith). When a plant absorbs water from the ground, it will also absorb the nutrients that it needs to live, breathe and reproduce. Nutrients are vital to the plant's survival, and because of the chemical make-up of some types, will leave a residue long after the individual plant has died and been absorbed back.Learn More
Phytolith Analysis. Using our state of the art laboratory facilities and expertise in the departments of Archaeology and Geography and Environmental Science we can offer a full pollen analytical service. From preparation of samples from sediment to slide, (including duplicate slides where required, with return of surplus material from the preparation); to quick assessments, (100 counts per.Learn More
The potential of phytolith analysis Greater experience with the phytolith taxonomy of present-day plants enables researchers to detect some plant taxa in archaeological sediments based on silica microfossils. The most studied phytolith assemblages come from Central and South America (Piperno 1998a, 1998b; Piperno et Becker 1996; Piperno et al 2000; Piperno et al 2001), North America (McClaran.Learn More
Get this from a library! Phytolith analysis: an archaeological and geological perspective. (Dolores R Piperno) -- This is a methodological guide to the use of plant opal phytolith analysis in paleoenvironmental and paleoecological reconstruction. It is the first book-length treatment of this promising technique.Learn More
Phytolith Analysis. Phytolith studies are important in reconstructing an approximate profile of vegetation present in local environments through time. In many plants, phytoliths are durable, microscopic bodies formed of silica absorbed through groundwater. Inside the plant, the silica deposits harden and form “copies” of the plant cells. Opal phytoliths, as they are called, have.Learn More

Phytolith analysis is now a popular technique in palaeoecological and archaeological investigations. Phytoliths can tell us much about past environments and agriculture, what animals and people ate and more. Considerable progress has been made on phytolith taxonomy with the development of the International Code for Phytolith Nomenclature 1.0 (version 2.0 is in progress). A combination of image.Learn More
