Overton, NV

 We were walking around near our chosen spot at Poverty Flats and I looked down and saw this rock that had the imprint of sea shells on it.  

When we looked closer we found on 2 other sides there were some round marks.  Looks to me like it was a 22 shell impression.  

Suzi researched it and it was actually a Crinoid Seal Lily fossil.

I feel like there is a mark on this side also, but maybe not...
