1.9" Fossil Fern (Pecopteris) Pos/Neg - Mazon Creek
Pecopteris is an extinct family of seed ferns. That is to say, it reproduces by dropping seeds rather than spores as with many modern ferns.
Over 500 animal and 200 flora species have been described from Mazon Creek. The event that caused this die off and preservation is believed to have started with a catastrophic flood event that buried the biota of the modern day Mazon Creek area. The deposition of river-borne silt and clay, brought on by upland erosion and delta progradation, contributed to the incredible preservation of one of the most complete records of Paleozoic biota.
This site has been collected for more than 100 years, and likely will continue to be collected by both professionals and amateurs for many years to come.
Comes with an acrylic stand.
