Marvellous microfossils (Part 2): The fascination of Microfossils from the Gault of Folkestone

Joe Shimmin (UK) The beauty and variety of the microfossils of Folkestone’s Gault Clay cliffs has amazed me ever since I was about 14 years old. At about this time, I had the good fortune to see some samples sent to me by Jim Craig, who I had met at the site. These microfossils roused in me such enduring enthusiasm that I eventually wrote an article entitled Marvellous microfossils (Part 1): Collecting Microfossils from Folkestone on how to process Gault Clay to obtain. This is the second article on this topic. Apart from the fact that the Forams, Ostracods and other microfossils found in the residue left by wet- sieving Gault Clay are interesting and unusual, in themselves it is also a bonus that there are vastly more of these fossils, in terms of numbers, to be found than the larger fossils that people usually go there to collect. If you collected hundreds of these larger fossils from a site in one go, you might be seen to be selfishly depriving other collectors of the opportunity to collect some for themselves. However, within 1kg of Gault Clay, there are literally thousands of microfossils. Therefore, removing a few kilograms of Clay from the site will do no damage whatsoever. So, within reason, you can build up a huge collection of a vast variety of microfossils with minimal impact on the site. These reasons have led me from writing the article referred to above to attempting to write a small book (or, … Read More
