What does a Certificate of Authenticity mean when buying fossils?

When you buy a fossil, you're not just acquiring an object – you're acquiring a piece of Earth's history. But how do you know if the fossil is truly authentic? And what exactly is included in a certificate of authenticity? In this article, we explain what such a document entails, why it is so important, and what you should look out for when buying.

What is a Certificate of Authenticity?

A certificate of authenticity is an official document issued by the dealer or seller that records the most important information about a fossil. It serves as proof of authenticity and as permanent documentation of the piece – both for the buyer and for future generations.

What should a good certificate contain?

A reputable certificate of authenticity contains at least the following information:

  • Scientific name: The Latin name of the genus and species (e.g., Dactylioceras commune)
  • Geological epoch: In what era did the animal live? (e.g., Lower Jurassic, approx. 180 million years)
  • Find locality: Where was the fossil found? (e.g., Holzmaden, Germany)
  • Condition of preservation: Is the fossil complete? Are there any restorations or additions?
  • Dimensions and weight: For clear identification of the piece
  • Dealer information: Name and contact details of the issuing dealer

Why is the certificate so important?

A certificate of authenticity protects you on several levels:

  • Protection against fakes: It confirms that you have purchased a genuine fossil and not a replica or fake.
  • Transparency in restorations: Many fossils are professionally restored. A good certificate openly states the extent to which this has been done.
  • Preservation of value: Should you ever want to resell or bequeath the fossil, the certificate is an important part of its provenance.
  • Scientific value: For collectors and researchers, the documented origin of a fossil is of great importance.
