Scientists discovered that a widespread network of bony skin structures, called osteoderms, exists beneath the scales of Australia’s well-known monitor lizards, or goannas. This finding, long overlooked, will help us understand how these ancient reptiles survived and thrived in one of the toughest environments on Earth.
To come into this piece of information, Roy Ebel, the study’s lead author and a researcher at Museums Victoria Research Institute and the Australian National University, expressed his surprise at the discovery. Furthermore, he noted that they found osteoderms in 29 Australo-Papuan monitor lizard species where these structures had never been documented before. The graph tries to show the representation of a fivefold increase in the known instances among goannas.
Moreover, it can be confirmed after the points that osteoderms are recognized in crocodiles, armadillos, and some dinosaurs, like Stegosaurus. However, the exact evolutionary function of osteoderms remains largely unclear. They have the possibility to offer protection; scientists are now wondering if these structures could have the possibility to help thermoregulation, mobility, and calcium storage during reproduction. Institutions such as the Museums Victoria Research Institute play an important part in preserving biodiversity, making researchers study species long after their collection.
Dr. Jane Melville, Senior Curator of Terrestrial Vertebrates at Museums Victoria Research Institute, expressed her excitement about the finding, and she noted that it changes our understanding of reptile evolution. Before this study, people believed that only the famous Komodo dragon possessed osteoderms in monitor lizards. It should be mentioned that this landmark study not only tries to add a new chapter to the story of Australia’s goannas but also heavily tries to provide a much more valuable dataset for exploring the complex relationship between skin, anatomical structure, and survival over millions of years of evolution which could be mentioned so far for now.
