Aztec Rex, also known as Tyrannosaurus Azteca, is a film directed by Brian Trenchard-Smith and starring Ian Ziering.

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.

An Aztec who is not aware of the Tyrannosaur is eaten, while another witnesses the event with an expression of deep horror and surprise.

Eventually Rios is found by Ayacoatl and Fra Gria who marries them at their request, the Chief (who witnesses) gives blessing to the union before passing away in peace.

Ayacoatl then cuts out Xovozin's heart to use as bait for the female Tyrannosaurus who then is killed in a gunpowder explosion.
