High precision geochronological techniques have dated Burmese amber in Cretaceous Period, specifically in Cenomanian Stage, 99 million years old. Burmese amber formed at a time of a major change in life on earth. The Angiosperms plant were radiating rapidly, which had a major impact on the Arthropod fauna. This reflected in the amber as it contains a mixture of extinct and living families. Burmese amber is located in the hill area in the southwest corner of the Hukawng basin,{Hukawng valley} Kachin state, northern Myanmar. The mining still carried out by Kachin people by manual method.
