Search the boulders and loose shingle west of the Cobb on a falling tide. Big ammonites sit in the grey boulders — photograph those — while smaller loose ones hide in the gravel between. The famous ammonite pavement is for admiring, not hammering.
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 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.
Rules can change — check locally before you collect.

Holmbush car park above the Cobb, or Monmouth Beach car park by the boatyard.
Toilets and cafés around the Cobb; fossil shops in town.
Walk west past the Cobb; the famous ammonite pavement is exposed at low tide.
The ammonite pavement is only safe on a falling tide — you can be cut off returning. Ledges are very slippery. Do not hammer the pavement: it is protected.
