Description
Offered here is a 100% genuine British fossil fern plant, preserved in fine detail from the Carboniferous period, approximately 300 to 320 million years ago. This beautiful specimen was discovered in Radstock, Somerset, a classic UK locality known for its fossil-rich geological layers of the Coal Measures Group.
The Coal Measures are a key component of the Upper Carboniferous System in the United Kingdom and consist of:
- Lower Coal Measures Formation
- Middle Coal Measures Formation
- Upper Coal Measures Formation
During the Carboniferous period, the region that is now the British Isles lay near the equator and was covered in dense, swampy rainforests, forming an incredibly biodiverse ecosystem. These tropical wetlands were dominated by large vascular plants including ferns, lycopods (clubmosses), seed ferns (pteridosperms), and horsetails, many of which grew to enormous sizes. The remains of this vast forest floor accumulated over millions of years, becoming compressed and fossilised to form the rich coal seams found today.
This specimen likely represents the foliage of a true fern or seed fern, featuring delicate leaf impressions preserved in shale or mudstone. Fossils from this environment offer extraordinary insight into Earth’s early plant evolution and climate.
