Aztec Rex

Taking place in 1521 on the coast of Mexico, a group of Aztecs worships and makes sacrifices to a pair of living Tyrannosaurus rex. A group of conquistadores led by Hernán Cortés later arrive on the location and venture into the forest to make camp. One of the Tyrannosaurs crosses the path of one of the conquistadores and devours Cortés's horse. His fellow conquistadores do not believe his story and continue to venture through the dense forest. An Aztec who is not aware of the Tyrannosaur is eaten, while another witnesses the event with an expression of deep horror and surprise. Later, the conquistadores try to kill the tribe of Aztecs, but are put to sleep by a hidden Aztec with a tube of tranquilizer darts. Hernán Cortés surrenders and demands a truce, but realizes they cannot understand him. He murmurs to himself that they are savages, not realizing the chief can understand Spanish, and is knocked out. Once he regains consciousness, he meets a Spanish-speaking female Aztec. She tells him the Aztecs call the Tyrannosaurs "Thunder Lizards".
