Dinosar Eggs

Actually these dinosaur eggs are really called Concretions. On our way back from Boulder we had a great time hunting them. They are formed from Iron separating from the sand and forming a shell. I wish I understood more of the particulars but I don't. Kelly really enjoyed this part of our trip!

They're actually called "Moqui Marbles". Read about them here:

I also found this site about them. Looks like they have a lot of different nick-names.
