Burmese amber

Burmese amber, or Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. It is important for its fossils from the earliest part of the Upper Cretaceous, in the Cenomanian age, 99 million years ago. The amber has been commercially exploited since the first century AD. Research on the deposit may fund internal conflict in Myanmar.
