Description

Details

Beautiful polished examples of Rhynie Chert from the village of Rhynie in Aberdeenshire, Scotland. This is a rare and highly sought after early Devonian sedimentary deposit containing fossils of the earliest land colonisers. It contains the best preserved land plants known from +400 million years ago making it incredibly important to science. The chert formed from silica rich waters which were ejected from hot springs and geyers in Rhynie during the early Devonian period. The silica rich waters coated plants and animals in close proximity to the springs and their organic remains were mineralised. After millions of years of burial these silicic deposits became the Rhynie chert that we see today. Our examples have been cut and polished to help reveal the organic structures preserved within the deposit. Each piece measures 1" x 1" and is supplied in a card tray with an information label.
