Dragons depicted on the belt-plaques are shown in motion, as if curling spirally, as opposed to the traditional Chinese dragon which is often shown moving in a zigzag fashion.
The image of a dragon served as a talisman and was supposed to protect the owner from danger, researchers suggest. Belt-plaques found in different caches differ in both their size and details, which lead the scientists to believe that they were manufactured in series but according to a single canon.
The Iyus cache was named after the settlement in South Siberia where it was found. The most ancient caches found in the region date back to the Mesolithic epoch, which are much rarer finds than caches the early Iron Age.
