Bivalve molluscs are very common. Gryphia, devil s toenails are popular with collectors. Belomnites are found in the hard white limestone. Some beautiful crinoids are to be found. Occasional large vertebrates are reported.
Heavy rain causes the cliffs to become waterlogged.
The resultant mudslides are normally channeled under the coastal road, but in some years the landslips are so bad that the coastal road has to be closed for some weeks while reconstruction work takes place. In some places, reservoirs are built to collect the mudslides on the landward side of the road. It is then taken across the road and dumped into the sea when the reservoir is becoming full. The sea does on excellent job of washing away the mud to reveal whole intact fossils, broken fossils, and boulders containing fossils. The best time for collecting is therefore the low tide of a spring tide following a period of storms, which was preceded by heavy rain.
