What was the world's most interesting dinosaur? Muttaburrasauruses of course!

Why? Was it because of their brown noses?

What killed the dinosaurs? Mutty and David ponder extinction (no, Mutty, you don't smell). Was it "fast food" that outran the dinosaurs? Was it an asteroid from outer space? Or was it a giant Indian volcano?

And what exactly did Mutty's ancestors eat? Bushes and trees or grass?

Mutty talks with David at Questacon. What about? Dinosaurs, of course!
