Fascinating Geology: Preserving Original Fossil Remains
After being preserved by experts and registered in accordance with the Fossil Conservation Act of 2008, the excavated fossil remains will be stored in a sample repository to maintain their condition as best as possible.
Storing and preserving fossil remains in a sample repository can be done in several ways. For example, they can be stored in separate sections based on the type of fossil, such as vertebrate fossils (with backbones) and invertebrate fossils (without backbones), plants, trace fossils, or categorized by the discovery site to facilitate easy retrieval. There should be knowledgeable personnel in paleontology to oversee and allow experts from other locations to study and compare conveniently. The storage room should maintain low humidity and stable temperature to ensure optimal preservation.
Maintaining a stable temperature is crucial because significant temperature fluctuations can cause fossil remains or fossils to contract and expand, leading to eventual damage and breakage. Additionally, controlling humidity is necessary because air moisture can react with minerals in the fossils, especially those containing salts, causing further deterioration and damage.
Suppose it's a holotype specimen, a specimen of a newly discovered species that is unique worldwide. In that case, it is used as a reference and for comparison with other specimens when researchers study it. It is stored separately in a room with a secure cabinet to prevent loss or damage.
However, holotype specimens are not displayed in public areas because they are at risk of breakage or damage. If such a specimen is damaged, it will immediately lose its holotype status.
