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 across settlements, agricultural practices, and seasonality of preagrarian site occupations. The durability of these microremains makes them particularly valuable at archaeological sites where preservation conditions are not suited to the survival of charred, desiccated, or waterlogged macro remains. Phytoliths provide both complementary and unique information about plant use at sites where charred macrobotanical remains (cereals, seeds) are present since these datasets preserve information about different suites of plant parts and enter the archaeological
