Collecting Microfossils
Belemnite Stone Beds, pockets of crinoids and belemnites
The best samples for microfossils are from the Belemnite Stone Beds. During the winter months, the sea exposes the clay at the base of the cliff, this also occurs during scouring conditions at other times of the year. A layer with pockets of crinoids and belemnites can be seen in the clay, these pockets occur at random areas, and it is the clay surrounding them which is superb for microfossils. The microfossils became trapped by the macro-fossils which is why these areas are so good.
Once you find these areas, take a sample of the clay around the sides, below and the pocket itself. Then start the sieving process at home or in the lab in preparation for searching for microfossils.

Searching for microfossils
The best way to process your samples is to soak in water for several days or a couple of weeks allowing the clay to dissolve. Once you have the sample broken down, use water to wash the sediments and remove any sand or ideally use a sieve and wet-sieve the samples at 500, 200, and 150 microns.
Sieves can be purchased from us, (under the 'What to Bring' section). You will need a microscope to view these. We sell a wide range which can be found under 'What to bring' page. Our most recommended model is the IMXZ. We can also help you with setting up your digital camera or viewing onto a TV.
