TRMS Field Trip Report Pennsylvanian Period Fossil Plants Coweta, Oklahoma January 11, 2009 Virgil G Richards Field Trip Coordinator Last month we had twenty-three folks turn out for the field trip to a local borrow pit near Coweta, OK. The weather cooperated beautifully for the activity and plenty of specimens were recovered by everyone. Some of the things found were sandstone and hematite impressions, casts, and replacement of various Pennsylvanian plants, carbon films, and coal layering. Some impressive yard rocks were wrestled into a couple of vehicles, and everyone appeared to enjoy their new discoveries. Some of the plant species represented was: Sigillaria, Lepidodendron, Calamities, and Cordaites. It is likely that other Lycopods and Gymnosperms were also represented in the finds. The following pictures represent a few of the specimens recovered: This mold measures more than a foot wide and is only a partial impression from the middle Pennsylvanian period and may represent a large Cordaites tree.
The next picture shows a nicely contrasting mineralized replacement of the pithy stem of a Cordaites leaf, called “Artesia”. This was found by Julia Allende.
This next photo shows a Calamites cast found by Tony Morris, and is the best one I’ve seen from this locality.
The photo below shows the base of a cone from one of the Lycopsids.
These are by far some of the best specimens I’ve seen from this locality. As the material from this borrow pit consumes and destroys thousands of examples of the remains of a Pennsylvanian age Mire Forest, these examples of 300 million year old fossils will survive for now and serve as proof of Oklahoma’s tropical past. ۞
