This radio broadcast explains how, by examining the clues trapped in amber, a remarkable insight can be gained into how life in the ancient forests would have looked, smelled and even sounded. Throughout the broadcast, there are extracts from a reconstruction of the vanished world of the Dominican amber forest. Scientists explain the difference between the deposits from the Dominican Republic and Baltic region, which reveal unique lost forests; how there is an upper limit to the size of an organism that could become stuck in the resin; and how some organisms lived within air bubbles in the amber. The broadcast from 2005 is 29 minutes in length.
