9.3" Carboniferous Fossil Fern (Callipteridium) Frond Plate - France

This is a fascinating and rare fossil seed fern (Callipteridium sp.) frond plate from the Late Carboniferous-aged Montceau-les-Mines Lagerstatte of France. This formation is Stephanian Stage in age, or approximately 300 million years old. The ferns are beautifully laid out on a rectangular-cut, 9.3 x 7.1", thick slab of rock. A truly incredible fossil fern plate!

Comes with an acrylic-metal display stand. There is some repair work through the rock/fossil where it broke during collection.
