A Spider Encased in Burmese Amber Burmese amber is one of the oldest ambers in the world, formed during the mid-Cretaceous period around 99 million years ago, and is found in the Hukawng Valley of Kachin State in northern Myanmar. The most important value of Burmese amber lies in its unparalleled significance for paleobiological research. It perfectly preserves snapshots of prehistoric tropical forests, making it a true "time capsule." The images of these insects were taken under a magnifying glass; please refer to the size information in the images below. We use PE boxes to store each piece of amber, ensuring its safety and ease of collection.
