Description: This amazing 13"7.5" carboniferous fern fossil is a true museum-quality piece. With bold fronds, including Pecopteris and Neuropteris, and stunning preservation, this fossil is sure to impress any collector or enthusiast. Excavated in St. Clair Pennsylvania in the United States, this piece is a rare find and a valuable addition to any collection. Believe it or not, these specimens are 100% natural. It is this exceptional state of preservation that gives the Saint Clair, Pennsylvania fossil ferns their great exquisiteness. It's hard to comprehend 100 years, let alone 3 million times that many, but these ferns died well over 300 million years ago! They fell into a swamp where silt, mud, and sediments amassed on top of them. Low temperatures, high pressure, lack of oxygen, and a lot of time helped these ferns slowly mineralize into Pyrite. Pyrophyllite (Aluminum Silicate) replaced the Pyrite at an ensuing stage, creating a bold white color. Any orange or gold tint that may(or may not) be present was caused naturally by the presence of iron ores. This unique type of fossilization makes these specimens perfect for mineral collecting as well as fossil collecting. The locality where these were mined from contained dozens of species, so look closely and you may very well find something rare. More commonly found are Alethopteris, Neuropteris, Pecopteris, and Sphenophyllum. Seed ferns went completely extinct around 73 million years ago, while the dinosaurs were still around! We NEVER paint, repair, or touch our fossils up. Nature and time are the artists. Perfect for display or educational purposes, this fossil is a unique window into the past. Whether you're a seasoned collector or just starting, this piece is a must-have for anyone interested in fossils and natural history. Don't miss out on the opportunity to own this exceptional piece of history. Feel free to contact us with any questions, thanks!.
