SANDWICHED IN: Amber: Jewel of the Earth. Forty million years ago a diverse community of insects living at the bottom of a tree in a temperate forest chanced into a sticky pool of pine resin. Then a mere 67 years ago a young boy named David Attenborough was given the amber stone containing the entombed bugs. Jewel of the Earth (56 min.), produced for Nova, explores the remarkable time capsule of ancient life preserved in this and countless other samples of fossilized tree resin, or amber. Sir David Attenborough, now grown up and a celebrated naturalist and TV personality, hosts the program. Join Garvies Point Museum geologist George Allgaier for a screening of this documentary. He will be bring samples and answer questions. 12:10 p.m.
