Field Book: Pennsylvanian Plant Fossils of Illinois

This field guide invites anyone curious about ancient plants to explore the rich Pennsylvanian fossil record hidden beneath Illinois' soils. Written for beginners, it walks readers through the basics of finding, collecting, and identifying the most common plant remnants, from primitive vascular stems to leafy ferns. Clear line drawings accompany each description, helping listeners picture the forms that once thrived 300 million years ago.

The book arranges the specimens in a handy time chart, linking each fossil to its modern relatives—such as the scouring rushes of Equisetum or the living cycad that echoes ancient Williamsonia. Alongside the visual guide, it offers a concise bibliography for deeper research and notes on the geological settings that preserved these treasures. By the end of the first section, listeners will feel confident spotting a Lepidodendron cone or a delicate leaf of Baiera in the field.
