Stereology and its impact on our understanding of human placental functional morphology.

abstract：:Phytoliths are an important component for interpreting the ancient botanical record. However, phytoliths can be altered through heating, either as the result of such activities as firing ceramics, clay molds use for casting metal or in hearths. Phytoliths can also be altered through heating as the result of creating c...
