• "A mid-Cretaceous age has been assigned to both the amber and surrounding rock. There are thousands of arthropods in the amber considered to be from the Turonian– Cenomanian, as well as a specimen of the ammonite Mortoniceras (Middle-Upper Albian) and distinctive palynomorphs (Upper Albian to Lower Cenomanian) from the amber-bearing horizon, among many other biological inclusions. A recent study using U-Pb dating of zircons in amber-bearing rock refined the date to 98.79 Ma ± 0.62 Ma. This date was further verified by a newly-discovered Late Albian–Early Cenomanian ammonite, Puzosia (Bhimaites), found among the amber inclusions. A 98.79 ± 0.62 Ma (earliest Cenomanian) origin is now the most widely accepted age for the Hukawng Valley amber mine" (Shi et al. 2022)
