The World's First Predator combines location filming, cutting edge science and stunning graphics to bring the earth’s first complex life forms back to life – and amongst them are some of the weirdest creatures ever to have lived.

Forget the great dinosaur sites of the world, or the sabre teeth of La Brea.  For scientists, the earth’s most important fossils come from a small limestone quarry high up in the Rockies.  Burgess Shale – dubbed the “crucible of creation” – provides a unique glimpse of the extraordinary creatures that appeared half a billion years ago.
