I have never seen anything like that before. Does it completely crumble if you touch it?? If not, and you can move one intact, try take a picture of it.

Definitely snail eggs, most likely Cerith snail eggs.

Cerith or nerite? My cerith look totaly different but when I google nerite eggs they look like the posted pics.
