Some paleobotanists study plant remains that have been abraded or degraded into microscopic fragments preserved in rocks and sediments. In the paleobotanical literature one can find references to such fragments described as being comminuted, macerated, or masticated, depending on whether the remains were broken up by mechanical means such as stream transport, wave action, or natural decay (comminuted or macerated) or by chewing and digestive processes (masticated).
