Nice finds. Great photos.  Spend the day there today.  Found the bivalves and oysters in creeks near the lake, and found some large and tiny ammonites as well.  Any tips on what/where to look for the echinoderms would be much appreciated.  Heading back soon.  

 

Looking at your photos and wondering about what I saw, I was curious- are the tiny ammonites part of a larger animate or are they separate individuals? What does the center of an undamaged large animate look like?  Thanks for any wisdom you can provide.
