First Animals at the Oxford University Museum of Natural History 

Some of you must know about THIS WONDERFUL SERIES OF VIDEOS but I only came across it by accident. It discusses, in great detail, the Cambrian Explosion.

My favourite (so far) is THIS ONE by Paul Smith, which among much else, describes looking for fossils in the very north of Greenland. But every thing I have seen so far is excellent and very professional - in the best sense!
