One Million Years B.C.Goofs

Throughout the movie, Raquel Welch is shown, from scene to scene, with and without shoes.

According to the fossil record, humans and dinosaurs were not contemporaneous. There were no dinosaurs one million years ago, having gone extinct 65 million years ago, however modern birds are descended from one branch of the dinosaurs.

The attacking Allosaurus is only about twice as large as his human opponents, when in actuality, it was at least five times bigger. Also, the Triceratops towers over Tumak and Loanna at the same height the Allosaur does, while the Ceratosaurus towers over the Triceratops. Allosaurus was much larger than Ceratosaurus. Of course, it could be speculated that the Allosaurus in this film was a juvenile creature.

Ceratosaurus was extinct when Triceratops existed, and they wouldn't have been in a situation to fight each other. Also, Ceratosaurus was much smaller than depicted in the film. An Allosaurus also appears, which, along with Ceratosaurus, was a Jurassic creature. Triceratops lived many million years later in the Cretaceous.

During the ape fight scene, one of the apes is thrown against the cave wall. The entire wall section bounces (moves) as the ape hits it.

As Loana drags the unconscious Tumak away from the attacking Achelon, actor John Richardson helps out by pushing himself along w/ his right leg several times.

During the cavemen's fight with the giant turtle, some of the rocks in front of the animal keep moving between frames or disappear entirely.

When the boy tries to steal the meat and has his hand stood on, he cries out and there is a lingering shot of his mouth showing fillings to his teeth.

The cavewomen's legs are shaved.

In the sunlight, the women's hair is soft and shiny with obvious professional haircut.
