The Paleokarsts and Cavefills project is driven by Roy Plotnick (UIC) and Fabien Kenig (UIC) with the collaboration of Andrew Scott (Royal Holloway, UK) and Ian Glasspool (FMNH at the time; now Colby College). This project led to many publications in the field of paleobotany, stratigraphy, and paleobiogeochemistry because of the excellent uncompressed preservation of plant fossils and the remarkable preservation of plant and arthropod tissues. The publications derived from this project are listed at the bottom of this page. The project was featured in the news.
Central Limestone Co. Quarry in Central, Kendall County, Illinois, USA
Lisbon Quarry, near Central, Kendall County, Illinois (Vulcan Material)
The Lisbon quarry is situated just west of Central quarry, though they are separated by a fault. The Lisbon quarry also display paleocaves and cave fills as well as clear connection with sinkholes (dolines) in the dolomites of the Plateville Formation. When these paleocaves were observed the cave fills already fell from the high wall, forming talus. For most paleocaves, these talus were already removed by the quarry operator.

Lehigh Quarry, Kankakee, Kankakee County, Illinois (Vulcan Material).
Dolines (sinkholes) at the top of the quarry are numerous on the North face of the quarry. This karst system formed in Silurian dolomites (Upper Llandoverian-Lower Wenlockian Joliet Formation) and the karst system is filled by argilaceous material of Pennsylvanian age. These dolines seem connected to a cave system that is visible on the second and third walls of the quarry. These caves are filled by clay as well. For more detail see Plotnick et al. (2014).
