Season 2

According to palaeontologist Bob Baker, there's plenty of evidence to show birds are dinosaurs. Using natural history footage of live animals combined with a detailed look at the fossil record, maverick paleontologist Baker shows us the evidence.

Ever since their discovery dinosaurs have ruled our imaginations. But one new kid on the block has outstripped all the others in its reputation for viciousness- the raptor.

A very long time ago, some tiny creature discovered how much more efficient it is to convert its neighbour into food than to convert sunlight into food. By the time of the dinosaurs, the ever-escalating arms race of predator and prey had brought about some of the most remarkable deadly killing machines that the Earth would ever see.

Palaeontologists are discovering and re-creating the mechanisms by which the dinosaurs gradually adapted to flight; and they're finding that the Pterosaurs were once as diverse as modern birds.

When the dinosaurs died off 65 million years ago, it was killer birds not mammals which dominated areas of South America.
