Monsters We Met (2003)

The first episode shows audiences the American Serengeti that was once North America, and the unearthing of a Clovis child who came from some of the earliest settlers of Montana. The people hunt Caribou and Mammoths as they hide from the Smilodon and run from Arctodus simus - the dreaded Short-Faced Bear. The second episode is set 65,000 years ago, Australia was a forested land of many green plants and megafauna such as Diprotodon. The continent also housed territorial large birds like genyornis and the menacing giant monitor lizard Magalania. The ancient Aborigine found their way to the shores of this strange land of giant Marsupials and Reptiles. The third and final episode is set in the 1200s, and we catch a glimpse of the Maori traveling to New Zealand after their hero Kupe first discovered this magnificent world of birds and flightless bats. They develop a taste for Giant Moa just as the amazing Haast's Eagle had a new taste for man. However, the fastest extinction process wiped the Moa out, and the Haast's Eagle would follow the bird. The episode continues to show how Hawaii and (to an even more horrifying extent) Easter Island suffered the same fate in the end of the episode.
