Informations supplémentaires

Fossil Ferns, St. Clair, PA Neuropter ovata, Pecopteris and Cordaites Species These fossil ferns are preserved in brilliant white impressions on dark shale, a result of natural bleaching by pyrophyllite-rich hydrothermal fluids. These Carboniferous-age plants thrived in lush swamp forests over 300 million years ago. Neuropteris and Pecopteris represent seed ferns with delicate, symmetrical fronds, while Cordaites were ancient gymnosperms with long strap-like leaves. St. Clair is world-famous for these striking plant fossils, prized for both scientific value and visual contrast.
