Corrected entry: When the prisoners are being led through the city, there is a shot of a horse's skull on a vendor's stand. Horses were not native to the Americas, but were introduced by the Spaniards.
Corrected entry: In the scene where Jaguar Paw's wife is stuck in the cave, 2 animals are fighting and one falls into the cave. These animals were Tasmanian Devils and are only found in the island Tasmania off the coast of Australia.
Correction: This is a perpetuated myth similar to that of "slaves built the pyramids". The heavy Spanish horse was introduced, but native horses have been in the Americas since 12,000 BC. There have been written accounts of visitors having seen horse and wagons in such places as ancient Mexico (Hui Shen tells of his account in the 5th century). And some native Americans tell of stories of their ancestors having horses before the Spaniards arrival.
