متن کاملUsing plant microfossils from dental calculus to recover human diet: a case study from Tell al-Raqa'i, Syria
Dietary reconstructions based on plant microfossils, such as starch grains and phytoliths, have been useful in increasing our understanding of past human populations. Microfossils have been recovered from sediments, stone tools, and, more recently, dental calculus. Methods for recovering microfossils from dental calculus have yet to be firmly established and there is some question about potenti...

متن کاملInterpreting Late Precambrian Microfossils
Chia-Wei Li et al. describe microfossils found in Doushantuo phosphate rocks from Guizhou Province, South China that are about 580 million years old (1). Well-preserved macroscopic multicellular fossils associated with prokaryotic and eukaryotic microfossils from the same source rocks have been documented in several studies (2– 6). The Doushantuo fossils are outstanding in both preservation qua...
