Response by seller

Good morning! I'm sorry to see, that you are dissatisfied. As I'm a private person I can't issue a certificate. I took all the info from the original advertisement as I bought the piece here a few months ago and just sold it to be able to afford something else. That said, all certifications that come with fossils are worthless as long as they aren't provided by a museum or another scientific society. So every piece sold here is to be taken by one's best knowledge and believe.
