Everything you find is worth a closer look. Seeing inside is usually both surprising and rewarding, even if sometimes it's hard to get there. This was true of the pine cone, it took
a good deal of effort with a hacksaw to cut it in half.
On the top row is a teasel head and the pine cone. On the bottom row a poppy seed head
and an ammolite (given to me by a good friend). The ammolite is a fossilised opalescent ammonite. It's made up mostly of the same mineral as mother of pearl.
I was happy not to have to cut this in half.
