| Geology comments: The distibution trends for plant fossils in the Chester Series of the Illinois Basin are interpreted as suggesting that successive, narrow deltaic lobes were built into the Illinois Basin during the Chesterian, and that only along these most active sites of depostion were land-plant habitats available. The restriction of plant fossils to the top of the clastic-dominated formations can be explained if the lower part of these units is interpreted as progradational, while only the uppermost part represents depostion on a delta platform. | |||
