English Flint Nodule Specimens with Cortex, set of 3

English Flint Nodule Specimens hand collected from the base of white cliffs of Southern England. The South of England’s coastline features "shingle" beaches which are made of accumulations of rounded, black Cretaceous flint that occurs as horizontal layers in the chalk cliffs. After flint nodules drop into the sea from the eroding cliffs, they are beaten into the material that forms these beaches. However, these specimens show the small nodules as they first enter the water, all with a distinctive white cortex. Sold in sets of three 2 to 4 inches long Natural, irregular shapes Our specimens are selected to show the characteristics of natural English flint. Most have a small flake removed so the interior black flint is visible. This variety of flint was extensively used for gunflint material and mined to make axe heads. Flint artifacts in England can be over 100,000 years old. Most of these are 2 to 4 inches in length and are curiously irregular in shape--great specimens for educators and collectors.
