Seasalter is a good place to hunt for London Clay fossils as it has an extensive foreshore allowing for collection at low tide.
Most of the fossils found at this site are contained within phosphatic nodules such as crabs. These phosphatic nodules are creamy in colour and can be difficult to identify. To determine if one of these nodules will contain a fossil some black markings should be visible, where legs or other parts of the fossil are being exposed.
Within the shingle areas smaller fossils can be found such as shark teeth and smaller phosphatic nodules.
Since Seasalter only has collecting avaiable at lowtide it is recommended to only visit the site about 1 hour before lowtide as this will provide a large time window for collection. The tide will come in quickly due to the low relief of the beach so it is important to stay mindfull of the tide times in order to not be submerged.
