Tiny tiny shells ....

.... for Tiny Tuesday.  I found these tiny little shells on Brighton Beach in South Australia near Adelaide when I last visited my brother in 2010.  I had taken my lenses out so that I wouldn't risk losing them in the sea and so was able to see the tiniest things nestling in the sand!  I've included a 20 pence piece to give an idea of how minute and perfect they are!  Many thanks to Trisharooni for hosting Tiny Tuesday.
