In North Attleboro, Massachusetts, I made a fascinating discovery: fossils of Neuropteris ferns. These ancient seed ferns date back to the Carboniferous period, approximately 359 to 299 million years ago. What sets these fossils apart is their captivating ability to fluoresce under certain lighting conditions. This distinctive glow is due to minerals that have over time replaced the fern's original organic material. When these minerals come into contact with specific light wavelengths, they emit a radiant glow, beautifully revealing the fern's detailed structure. Such a find in North Attleboro provides a captivating glimpse into the area's prehistoric ecosystems and geological past.
