Discovering the lost world of the amber forests.
Wednesday 16 February 2005 9.00-9.30pm

Howard Stableford embarks on a wonderful detective story following the听clues which lead him to the lost world of the amber forests.

Millions of years ago, a forest flourished in the Dominican Republic. One of the species of tree exuded copious amounts of resin which acted as a sticky trap, capturing and holding small insects and other animal and plant debris.听The resin hardened and over thousands of years a process of fossilization took place.

In this programme, Howard joins the 鈥渁mber detectives鈥, the scientists for whom the study of amber has been a lifelong passion. By examining the clues trapped in the amber, Howard gains a remarkable insight into how life听in the ancient forests听would have looked, smelled and even sounded like!

Amber occurs in many parts of the world. Most of the amber which is used in the commercial production of jewellery comes from the Baltic region or the Dominican republic.听The oldest recorded amber comes from the Upper Carboniferous (approx. 300 million years ago). The oldest know amber containing insects comes from the Lower Cretaceous (approx. 146 million yeas ago).

The plant and insects inclusions preserved in Baltic amber indicate that it was produced in a subtropical forest with a mixture of trees. Dominican amber inclusions indicate that it was formed in a tropical forest.

Throughout the programme, we hear abridged extracts from "The Amber Forest", written by amber experts George and Roberta Poinar, which is a fascinating reconstruction of a vanished world the Dominican amber forest. When Howard meets George Poinar, (Courtesy Professor at Oregon State University) he gets the chance to examine听a beautiful jumping spider trapped in a piece of amber under a microscope.

Howard also meets David Grimaldi, Curator of Invertebrate Zoology at the American Museum of Natural History in New York.听David听shows Howard听some amazing examples of amber inclusions including a tiny skeleton of a lizard which died on the surface of a resin flow, decayed, and then was covered by more resin, so the skeleton is beautifully preserved.

Last, but by no means least of our three amber detectives is Andrew Ross, Curator of Fossil Arthropods at The Natural History Museum in London.听Like the two other 鈥渁mber detectives鈥, Andrew has spent many years studying the fossil inclusions and trying to get an insight into life in the ancient amber forests.

Amber 听is a fascinating detective story and a wonderful and evocative journey through time, as the programme captures in sound, the lost world of the amber forests which existed millions of years ago.

The wildlife sound recordist was Chris Watson.
