Have recently seen many small curved objects on the beach. They appear
to be just sand - pick one up and it breaks up into nothing but sand.
Therefore, I rather assume they are some sort of cast. Possibly some
sort of protein binding it all together.

Each one is something like 75 mm long.

Across the beach there must be untold thousands:

I have tried image searches - Google, TinEye, Bing. Nothing I've found
so far matches!

Any good ideas about how to preserve one - as a specimen? Obviously,
without changing its look. Has to be a simple technique using pretty
safe materials as it would have to be done on a public beach.

Hair spray?

Need some kind of spray on fixative, I would say.
