360 Million Y/O Alethopteris Fossil Fern Mounted on a Custom Acrylic Stand
About the Item
Name: Alethopteris
Origin: Llewellyn St. Clair Formation, Pennsylvania
Period: Carboniferous 300 to 360 Million Years
They are plants similar to ferns, they were part of the largest of the time, the trees reached about 10 Mt. in height and their branches reached up to 7 Mt. in length.
A very particular characteristic of this formation is that during the strong storms that occurred in that period, many of the plants died and remained sunk in the marshy bottom of the lagoons, without oxygen, creating the perfect environment for fossilization, in the first instance due to the slowly and little pressure, the pyrite replaced the organic material giving an orange color, then as the temperature and pressure increased, the pyrite was replaced by pyrophyllite, which produced its characteristic white color, it is common, however, to find plates with the white and orange, making them very interesting pieces for collection.

Plants are multicellular, photosynthetic eucaryotes. The oldest known land plant body fossils are Silurian in age. Fossil root traces of land plants are known back to the Ordovician era. The Devonian was the critical time interval during which land plants flourished, and Earth experienced its first “greening” of the land. The earliest land plants were small and simple and probably remained close to bodies of water. By the Late Devonian, land plants had evolved large, tree-sized bodies, and the first-ever forests appeared.
Glossopteris is probably the most familiar fossil leaf...
