What's an SSSI, and can I still collect?

Most of Britain's great fossil beaches are Sites of Special Scientific Interest — SSSIs. That sounds forbidding, but for beach fossil hunters it usually isn't.

An SSSI protects the cliffs and the rocks in place — the pages of the book, if you like. It does not usually stop you picking up what has already fallen out. A fossil lying loose on the beach has been torn out by the sea; the next tide will grind it to sand. Rescuing it is not just allowed at most sites, it's positively useful.

The rules that matter, almost everywhere:

Loose on the beach? Usually fine to keep for a personal collection.
Still in the cliff, ledge or bedrock? Leave it. No digging, no hammering — it is illegal at many protected sites and dangerous at all of them.
Something special? A bone, a big skull, anything unusual — tell the local museum or heritage centre first. You'll usually still be credited as the finder, and scientists get the context they need.

A few places have stricter local rules (Kimmeridge Bay, for example). Every beach page on this site has a "Can I take fossils home?" panel with the local position — and rules can change, so when in doubt, ask locally. The people who run our coast's heritage centres love talking to collectors.
