Each show featured about twenty seconds worth of spectacular CGI. Twenty seconds will have been all the budget would stretch to. So they showed the twenty seconds over and over again- sometimes with the image reversed or the sequence played backwards. By the end of the hour you'll have seen it God knows how many times.
The better of the two programmes was about the dinosaur mummy they recently dug up in North Dakota. The fact I'll take away with me is that dinos were fatter than we've been thinking they were. And fatter means faster;- bigger muscles, see. This thing was a hadrosaur- a prey animal- and the best estimate is it could easily outrun a T Rex. It ran funny too- on two legs but with the body parallel to the ground- in a sort of a crouch- unlike any creature that's alive today.
Much of the work on the North Dakota dino is being done at the University of Manchester. Yay!
