Leilão Bidspirit | A large collection of fossilized

A large collection of fossilized shark teeth arranged in a clear display box. - The collection is arranged in a transparent, rigid Plexiglas honeycomb. The items can be arranged in a different order in the honeycomb. Dimensions of the honeycomb: 14X14cm. These fossils are the teeth of ancient sharks that have undergone a process of fossilization over millions of years. In this process, organic material such as tooth enamel is preserved by turning into stone when minerals from the earth crystallize around it. Characteristics of the collection: Variety of species: The collection may include teeth from various sharks (such as a nurse shark or a white shark) as well as the teeth of the great white shark. Source: Such teeth are often found in geological layers from periods such as the Eocene or Miocene, and are collected in coastal areas or rivers. Appearance: The fossils are characterized by a natural shine and dark shades of black, brown and gray, resulting from the minerals that have been absorbed into them over the years
