Trapped in Amber

George Poinar has found evidence in fossil amber that diseases like malaria might have plagued the dinosaurs, even helped force them into extinction. In this audio slide show, Poinar guides you through a gallery of fossil plants and animals, some containing disease microbes, that have been preserved for millions of years in amber.
