Rhynie chert

Rhynie chert is a geological formation in Aberdeenshire that preserves tiny organisms from the early Devonian period in silica-rich rock. The fossils show plants, fungi, and animals that were rapidly mineralized in the sediment and retain their detailed structures today.

William Mackie discovered this formation between 1910 and 1913, making it central to research on early terrestrial life. His findings revealed how organisms lived during a major transition in Earth's history.

The site serves as a primary resource for paleontologists and geologists studying the transition of life from water to land environments.

The site is protected and requires permits for visits or research work. Visitors should contact local authorities before traveling to confirm access and conditions.

Individual cell walls and internal plant structures remain visible in polished specimens because mineralization happened extremely fast. This is unusual for fossils from this time, as details are typically lost.
