Stars Ward Ramsey, Kristina Hanson and Paul Lukather. A frozen Tyrannosaur, Brontosaurus and caveman unthaw from watery depths and find themselves in the 20th century. A young boy befriends the Bronto and even gets a ride. While the Tyrannosaur is just plain nasty (as expected) and the caveman provides the humor as he tries to cope with a modern world.
The unforgettable climax has the T. Rex battling a steam shovel! Real quality kids entertainment for 1960.
