Other Southern Illinois Localities
Other collecting localities have been recorded west of McLeansboro in Hamilton County, northwest of Mt. Vernon in Jefferson County, near Grayville in White County, and in the Friendsville area of Wabash County. There is no doubt that careful search will turn up many more.
Almost anywhere in the large coal producing areas of southern Illinois plant fossils can be found either in spoil heaps or in outcrops along stream, road, and railroad cuts. The thick Pennsylvanian sandstones that crop out in a belt extending through Gallatin, Saline, Williamson, and Jackson Counties generally contain compressions or replacements of trunks or other woody plant parts.
