Where to look
Search the London Clay foreshore for rounded brown nodules and pyrite fossils lying on the washed surface — but only on firm ground, never out on the open mudflats. The freshest material appears after a north-easterly blow.
What fossils look like here
Shark teeth are glossy, dark and triangular — usually under an inch, lying in the low-water gravel. Pyrite fossils look like brassy twigs. Rounded brown nodules with rusty cracks can hide crabs and turtle bone. Identification: photograph finds for the Natural History Museum's identification service.
Allowed: Loose fossils from the beach and foreshore may be kept; sieving loose gravel is fine.
Never allowed: No digging into the cliffs or sea defences on this SSSI coast.
Important finds: Unusual finds (bird bones, complete crabs, turtle material) are scientifically valuable — photograph them for the Natural History Museum.
Rules can change — check locally before you collect.
Limited parking at Warden Bay / Warden Springs area.
Facilities
Very little nearby — bring everything you need.
Access
Access points change as the cliff erodes; follow current signed paths down.
Hazards
The London Clay foreshore hides deep, dangerous mud that has trapped collectors — test every step and never cross the open mudflats. Actively collapsing cliffs; go on a falling tide only.
