How to Distinguish Between Real Dinosaur Bones and Artificial Reconstructions
Museums are home to some of the world's most fascinating treasures, including original dinosaur bones that have been preserved and displayed for the public to see. However, sometimes these fascinating specimens are not the real deal but rather artificial reconstructions. How can visitors or curious individuals tell the difference between original mineralized fossils and artificial bones? Here are several methods that can help you make an informed decision.
Visual and Textural Distinguishing Features
Modern museums have evolved in their approach to presenting dinosaur exhibits. Many now opt for a clear color and texture contrast when displaying both real fossils and reconstructions. Reconstructed parts often use a single neutral color, such as gray or brown, and tend to be smoother than actual fossil parts. This contrast is designed to inform visitors about the authenticity of the specimen on display.
A common technique involves making cast copies of the original bones, allowing the real fossils to remain protected in the museum's collection. When a cast is displayed, it is typically labeled with information indicating it is a copy, such as "cast of original." Visitors can also identify the nature of the exhibit by observing the mounting itself. If the frame of a display looks like it goes right through the bones, it is likely that these are cast and not original specimens.
Heavy and Supported Original Fossils
In some cases, museums maintain the display of original bones, even if they are heavy. A good indicator of this is to look at how the bones are mounted. If the display features a significant amount of metal with collars, cradles, and steel bands, these are likely supporting original fossils. As these bones are valuable for both scientific and historical value, museums often want to preserve them in their entirety.
One example of such a display is the Eremotherium, a giant sloth. This exhibit showcases extremely heavy original bones, and upon closer inspection, one can observe a multitude of metal rods and cradles. The supporting structure, shaped like a tree, is designed to hold these massive bones securely.
Display Poses and Preservation Efforts
For some visitors, the use of casts instead of original bones can be disappointing, as it restricts the creative possibilities of exhibit design. However, displaying casts has many advantages. It allows museum curators to create more dynamic and visually engaging displays without risking the safety of priceless artifacts. Furthermore, it ensures that the original bones remain protected, preserving them for future generations to study and admire.
When a display is labeled as a cast, it means that the original fossil is being carefully preserved and stored away from public view. This practice helps in maintaining the integrity of the fossil record and allows for the continued scientific study and conservation of these precious specimens.
By understanding these methods, visitors to museums can appreciate the nuances of dinosaur exhibits and gain a deeper appreciation for the care and attention that goes into their preservation. When you come across a display marked as a cast, remember that this is a testament to the museum's dedication to both public education and the preservation of our natural history.
In conclusion, museums employ a variety of techniques to distinguish between original dinosaur bones and artificial reconstructions. Understanding these methods can help visitors appreciate the integrity and scientific value of the dinosaur exhibits they see.
