I have posted 3 pictures on the web of a shell I found on the shore of the Clyde Estuary in Scotland, UK. It is almost certainly an ice-age subfossil as many other subfossil species can be found nearby. It measures 66mm across. The pictures can be seen at at http://www.geocities.com/slongrigg/mystery1.html Any ideas? Sorry they have rather a blue cast as I haven't had time to correct them yet.
