By detailed study of the components of each bed of rock - the microscopic particles that form the body of the rock, the plant and animal fossils, the chemistry of the stone, and the subtle changes in thickness and composition across a quarry face, geologists can piece together reconstructions of how the rocks formed and what this area was like millions of years ago.
