Finding Fossilised Sea Urchins

Good morning from the bottom of a prehistoric ocean that is now the top of the Southdowns!

Up here at Lewes in Sussex is the top of an approx. 600 foot layer of chalk that is in fact the fossilised remains of plankton skeletons that settled on an ancient seabed. The chalk here is approx. 50 million years old and down several hundred feet below it is 100 million yrs old!

Fossils here are mainly Sea Urchins that occur preserved in the chalk or sometimes in the flint rock layers. I will add another video asap to show you the difference between them and how best to prepare and display them. Watch this space!
