trilobits

Hard to see, but it looks like a bit of upside down trilobite in he middle.

Mostly Crinoid stems

Cambrian crinoids, brachiopods and the bow shaped thing is part of a trilobite.  They molted, which is probably why so many trilobits are found.  Northern Kentucky

I think this is going out to be a yard rock.  It is pretty fragile, so I thought I'd photograph it first.  What I like is the delicate shells which seem to still have a bit of shine to them after, what, 250 million years or so.
