When in Kentucky looking for Geodes, I began finding crinoid stems, and other fossils and decided I needed to collect more of them. When I got home I realized I had no reference books on them. I looked on Ebay found 3 books I like and this was one of them. It will be a guide I will use over and over as it is an amazing collection of fossils that are very findable in North America. I am delighted and would purchase from this seller again!
Have a nephew with a passion for fossils, it has great photos and wonderful descriptions for those with an interest - phenomenal book for kids and adults.
