Good day to hunt
Safe window: 9:20am – 12:20pm
Leave the beach by 12:20pm — the tide will cut off your route back.
Why: A recent westerly blow should have brought fresh cliff material onto the beach. An early-autumn blow like this restocks beaches after the quiet summer. Low tide falls at lunchtime, though it is not an especially big one.

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.
