Abstract Two methods are commonly used for the extraction of phytoliths from plant material to be used as reference in the analysis of archaeological phytolith samples: (1) spodograms or dry ashings; and (2) acid digestions or wet ashing. It has been suggested that these techniques may modify the resultant samples in different ways. Dry ashing, in particular, has been implicated as a cause of shrinkage and warping in phytolith assemblages when incineration occurs at ≥450°C. The results of a… 

Comparing dry ashing and wet oxidation methods. The case of the rice husk (Oryza sativa L.)

The results showed that processing methods have an impact on the morphology of two subspecies of rice phytoliths, dry ashing producing more conjoined cell phydoliths or multicells phytolithic cells than acid extraction.

Multi-analytical characterisation of wheat biominerals: impact of methods of extraction on the mineralogy and chemistry of phytoliths

Phytoliths from two different wheat species, Triticum monococcum and Triticum durum, known for their long-lasting significance to humans, were studied by a multi-analytical approach. Characterisation



A comparison of three methods for the extraction of phytoliths from sediments

Abstract This paper compares three methods commonly used to extract fossil phytoliths from sediments. A basic procedure using heavy liquid flotation and oxidation is compared with two other

Metric Analyses of Prehistoric Morphological Change in Cultivated Fruits and Nuts: An Example from Island Melanesia

The comparisons of archaeobotanical remains with modern reference material indicate changes in fruit size and shape through time, which probably reflect selection over the last three millennia by the cultivators for desirable attributes such as larger edible parts.

A typologic and morphometric study of variation in phytoliths from einkorn wheat (Triticum monococcum)

Variation between phytoliths produced in the laminae, inflorescence bracts, and culms of einkorn (Triticum monococcum L.) were examined and it was indicated that there are some significant differences between the mean morphometries of silica cell phytometries produced inthe lamina tissue and those produced inThe culm and inflorescence tissues.

Phytolith Taxonomy in Selected Species of Texas Cacti

For this study we examined sixteen modern cactus samples. Based on descriptions of phytolith surface features and ratios of size variations, we believe it is possible to separate certain cacti at the

Phytolith analysis for a wet tropics environment: Methodological issues and implications for the archaeology of Garua island, West New Britain, Papua New Guinea

Abstract The archaeology of prehistoric occupation of the island of Garua, West New Britain, is beginning to provide a detailed picture of human adaptation to a highly volatile environment in which

Identifying ancient irrigation: a new method using opaline phytoliths from emmer wheat

Abstract A vital factor in the rise of the first state societies is the development of complex farming systems employing labour-intensive irrigation. Ancient irrigation is, however, difficult to

Variation of silica bodies in leaf epidermal long cells within and among seventeen species of Oryza (Poaceae).

Morphometric procedures were used with scanning electron microscopy backscattered images to study silica bodies in epidermal long cells of four different leaf veins of 17 of the 20 species of Oryza, finding that bodies varied with respect to both size and shape.
