Trivia

There are two animals that can be linked as a proxy of animals that really co-existed with humans and were quite dangerous. The predatory big cats are often referred to as "sabre-toothed" cats, which could be true if one was using Machairodus or Homotherium as a reference. The giant condor could be based on Argentavis, a giant condor of the South American Miocene Epoch that is considered the largest flying bird to ever have existed. The Haast Eagle seems to also be a source of inspiration, which was the largest bird of prey ever to take flight and existed in New Zealand from the end of the Pleistocene to the middle of the Holocene in approximately 1400 A.D., when their main food source, the giant Moa went extinct through human activity. What this has to do with the condor of this film, is that the Maori Settlers told stories of the bird carrying away children, men, and women, and was known to these people as the Pouakai. See more
