Every year, in northern Myanmar, thousands of farmers pull tonnes of Cretaceous amber out of the ground, and send the glistening nuggets to local markets. For six years, Bo Wang from the Chinese Academy of Sciences and his colleagues have visited the markets and sifted through 300,000 of the glistening nuggets. It was a lot of work.
