Are We Alone? SETI Institute Science Radio

Hosted by Dr. Seth Shostak

July 26, 2006 (available for download July 27, 2006) Dinos and Carnivorous Kangaroos

Dinos are still big, even though they vanished from the landscape 65 million years ago: it seems we just can't get enough of these economy-sized lizards.

Meet the only ichnologist* in Canada, and discover what he’s learned about dinosaur behavior from the footprints they leave behind.

Also, a new theory about what really obliterated these scaly hulks (are rocks from space out, and magma from Earth in?)

Plus, why T-Rex never needed corrective lenses and the discovery in Australia of ancient, flesh-eating kangaroos.

Guests:

• Rich McCrea – Palaeontologist at the Peace Region Palaeontology Research Centre in Tumbler Ridge, British Columbia
• Andy Saunders – Geologist at the University of Leicester
• Luann Becker - Geophysicist at the University of California, Santa Barbara
• Sue Hand – Palaeontologist, University of New South Wales
