It has small glued and tiny filled fractures. This specimen has been stabilized on its surface by Paraloid B 72 to ensure its stability and consistency. This process does not affect neither the color nor any of the characteristics. It simply makes the specimen better preserved in the long term. A beautiful and complete shark tooth of Squalicorax is associated in the same matrix. In the international
