Introduction
Hunstanton is an excellent place to find fossils and a highly recommended family location. The rate of erosion is great, due to the lack of sea defenses and subsequent wave action to the cliff base.
The location is one of the most spectacular geological formations, with the lower white chalk sitting on top of the striking red chalk - caused by iron oxide (rust) within the chalk. Below these two layers sits a grainy rock, known as Carstone - where it may be possible to find the occasional ammonite.
Where to look for fossils?
Fossils can be found in both the white and red chalk. During our recent visit we concentrated on the foreshore and recent cliff collapses.
A hammer and chisel are necessary to remove specimens from the boulders. A geologist hammer alone is not recommended because precision is required to prevent damaging the fossils.
The best way to find fossils is to carefully examine the weathered surfaces of the foreshore boulders. The wind, rain and sea have eroded the surface, leaving literally thousands of fossil pieces exposed. Most of the fossil fragments are from large mussel shells, these appear as chunks of brilliant white within the white chalk. Other common finds include echinoids (sea urchins) often partially exposed on the surface.

What fossils might you find?
The least common finds at Hunstanton are the ammonites, however this makes them highly prized and worth spending the time to find. During our recent visit, Brian (pictured below) found a wonderful ammonite specimen, partly exposed on a foreshore boulder. Close inspection of the surface indicated the position of the Sutures. The next step will be to prepare the fossil from the underside, which should hopefully be intact.

In summary, Hunstanton is one of the best locations in Norfolk to find fossils. The cliffs are simply spectacular and promise a good range of fossils. The best time of year to visit is the winter or after periods of heavy rain/seas, when the rate of erosion is at its greatest.
Protecting your finds
It's important to spend some time considering the best way to protect your finds onsite, in transit, on display and in storage. Prior to your visit, consider the equipment and accessories you're likely to need, as these will differ depending on the type of rock, terrain and prevailing weather conditions.

When you discover a fossil, examine the surrounding matrix (rock) and consider how best to remove the specimen without breaking it; patience and consideration are key. The aim of extraction is to remove the specimen with some of the matrix attached, as this will provide added protection during transit and future handling; sometimes breaks are unavoidable, but with care you should be able to extract most specimens intact. In the event of breakage, carefully gather all the pieces together, as in most cases repairs can be made at a later time...continued.
