Hello,

Can you help me please?
In the spring I get a rusty bucket with shell (and scree and litter <img src="images/smiley/smile.gif" alt="" border="0" />). They said it’s from Mediterranean area but I think it isn’t. (Maybe Africa?)

The shells are mostly these (size 2-5 cm): <a href="http://www.badongo.com/pic/10386171" target="_blank"><!-- m --><a class="postlink" href="http://www.badongo.com/pic/10386171">http://www.badongo.com/pic/10386171</a><!-- m --></a>
