Where to look
Search the gravel patches and rock pools below Thorncombe Beacon at low water. This quiet beach is rarely picked over — the tideline after a south-westerly blow rewards a slow, patient walk.
What fossils look like here
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).
Allowed: Loose fossils from the beach and foreshore are yours to keep — collecting them here is positively encouraged, because the sea destroys what nobody saves.
Never allowed: Never dig or hammer into the cliffs, ledges or landslide material; fossils still in place must stay in place.
Important finds: Register scientifically important finds with the Charmouth Heritage Coast Centre under the West Dorset Fossil Collecting Code.
