All fossils we sell are guaranteed to be 100% authentic, with no repair or restoration (unless specifically noted). We DO NOT SELL replicas and detailed photos allow you to accurately see what you are buying. We back this with more than 25 years of highly respected experience in the field and guarantee everything we sell. Remember a certificate of authenticity is just a piece of paper - it's the REPUTATION that gives you peace of mind. We won't jeopardize our reputation to sell you something that isn't a 100% authentic fossil.
