Where Are the Real Dinosaur Bones Kept?

While bone fossils are not the actual bones but rather casts that have been mineralized over millions of years, there are still many opportunities for you to see real dinosaur bones. These bones are primarily housed in museums, but they often require specific conditions to preserve their integrity. This article will discuss the various locations and methods used to store and display these fascinating relics from the past.

The Diverse World of Dinosaur Bones

It is true that dinosaur bones are not the only preserved remains of these ancient creatures. Even small mammals coexisted with theropod dinosaurs during the Jurassic and Cretaceous periods. However, birds, specifically theropod dinosaurs, are the only surviving members of that group today. This makes the distinction that 'dinosaurs' are merely a broad term for a certain group of animals somewhat debatable.

Displaying and Preserving Dinosaur Bones

Dinosaur bones are cherished by both scientists and enthusiasts. Many museums display individual bones, skeletal mounts, or even full skeletons. However, most of these skeletons are casts rather than the actual bones to prevent damage and ensure their longevity. Casts are accurate reproductions made from the original bones, providing visitors with a realistic view of what these ancient creatures looked like.

When displaying dinosaur bones, there are various methods used, depending on the availability and condition of the bones. Sometimes, bones are displayed individually, and other times, they are mounted together. In some cases, casts are used in place of missing bones or to recreate the entire skeleton. Storage, however, is crucial for the preservation of these valuable artifacts.

Many museums have extensive storage facilities equipped with technical expertise to maintain the proper conditions for long-term preservation. These conditions include optimal temperature, humidity, and light levels to prevent deterioration. Real bones, like other artifacts, can be affected by exposure to the elements, leading to decay and damage. Proper storage can help balance accessibility for study and exhibitions while also protecting the integrity of the bones.

Real Examples and Special Cases

One example of a well-displayed dinosaur skeleton is the full T. Rex skeleton at the Whitby Museum. Discovered in the Whitby area, this skeleton provides a vivid reminder of the prehistoric era. Additionally, the discovery of Whitby jet fossils in the vicinity adds to the significance of this location. These fossils are not only important for scientific study but also for those interested in the history and culture of the region.

However, displaying dinosaur bones comes with its challenges, particularly the preservation of the original fossils. Over time, pyrite within the fossils can break down, leading to corrosion. Museums use various methods to preserve these delicate specimens. One such method involves exposing the fossils to ammonia vapors, which can help stabilize the FeS2 to FeSO4 transformation. Some institutions also use chemical treatments like thioglycolic acid (silanes) or store the fossils in a very dry environment (below 15-20% humidity).

Conclusion

The preservation and display of dinosaur bones require delicate handling and specific conditions to ensure their longevity. While many bones are on display, the majority are stored in museums for conservation and research. By understanding the methods and challenges involved in preserving these prehistoric artifacts, we can appreciate the rich history and scientific value of these fascinating bones.
