Walk east towards White Nothe and search the foreshore ledges and gravel at low water — oysters and ammonites wash from the Kimmeridge Clay. The rock pools hold polished fragments the sea has already prepared for you.
Ammonites show as coiled ridges in grey limestone, or as golden pyrite spirals the size of a coin. Belemnites are smooth amber-brown rods shaped like rifle bullets. Ichthyosaur vertebrae look like dark, shiny cotton reels. Free identification: the Charmouth Heritage Coast Centre identifies finds in person and from emailed photos (charmouth.org).
This coast is a protected site (SSSI). What does that mean?
Allowed: Loose fossils from the beach are fine to keep for a personal collection.
Never allowed: No digging or hammering into cliffs or bedrock on this protected (SSSI) coast.
Important finds: Report scientifically significant finds to Dorset Museum in Dorchester.
