There has been a TV show here in Denmark a few times, actually two.
Nigel first goes back and see the seven most deadly seas of our planets history.
Then he travels back in time to "save" animals which will become extinct. He makes a park with two T-rexs, a lot of huge "longnecks" (can't remember their names right now, sorry) in one episode, he actually cought a Deinosuchus.
I wonder if any of you have seen it, and what is your oppinion to these movies?
