Corrected entry: There are several technological errors in this film. Firstly, the earliest known use of sailing ships was around 3500 B.C. The film shows humans riding horses, which were not domesticated until around 3500 BC. The use of swords and other bladed weapons is also terribly inaccurate, as the first use of swords dates back to only the late 3rd millennium BC in the Middle East and most certainly would have been made from copper, not from any grey coloured metals. And finally, there is a scene in the film with a telescope, which wouldn't be invented until the 17th century AD, not 10000 B.C.

Corrected entry: The Terror birds were indigenous to the Americas and had gone extinct 1.8 million years ago. Therefore never had any contact with humans.
