Cryptozoology / Dinosaur / Extinct Animal Species / Related Documentary Recommendations

I couldn't think of a more suiting section for this thread, so I thought this will do? I've asked about this (thread title) in other message boards, but I realized that if anywhere is the place to ask, it's on ATS, considering ATS goers have the best watch over this sorta stuff.

So I just finnished watching this "Giants of Patagonia" documentary, which I recommend everyone to watch (You can easily navigate to the following Parts (2,3,4 and 5) on the right hand side of this video.):

www.youtube.com...

It had me hooked the whole way through. So now that I've recommended my documentary, can you guys continue this thread by listing your recommendations (preferably your TOP one/s, because I bet the list can be pretty long). And remember it has to be strictly about Cryptozoology or Dinosaurs, or anything related. I guess I could allow documentaries on extinct human species (ie our ancestors) as well.

Any recommendations highly appreciated, as I'm dying for some new ones to watch!!

Note: I prefer recommendations that are watchable on Youtube, or just the internet in general.
