this is a 3 parter, they are all pretty awesome
this is a 5 or 6 episode series, all pretty decent
TV-Shows
at the bottom of this page they have all the bbc planet earth documentaries
the "walking with dinosaurs" series, but i cant find any link that seems to get most of the 5-6 episodes.
only other shitty thing is when i watched those first two documentaries they were not broken into 10 min segments, they were each about a hour long. now you gotta watch them in segments which kinda sucks.
