Dinosaur Science, Ancient Diets and Fossilised Crocodiles

27 February 2005
Presented by Chris Smith, Kat Arney.

This week David Norman discusses how dinosaur science is bringing fossils back to life by looking at dinosaur anatomy and physiology, including an explanation of how scientists are able to recreate dinosaur sounds. Also in the studio, Tamsin O'Connell describes how the chemical composition of ancient bone and hair can reveal what animals were eating and the technologies early humans used, and Paul Willis drops in twith a snappy description of how new crocodile fossils in Australia are helping us understand crocodile evolution. The contribution of Einstein to science in the home goes under the laser eye of Philippa Law, as she finds out how a CD player works.
