daughter's hair with tar, in an attempt to prevent her from being sacrificed like Sanna. Some weeks later, while Tara is hiking back to his tribe, which has been taken over by the overzealous Kingsor, he is carried off by a giant Rhamphorhynchus. After killing the pterosaur, he finds Sanna and her tamed dinosaur. They are subsequently discovered and Tara is sacrificed to a Tylosaurus by Kingsor. Tara manages to escape and returns to Sanna. The tribe then goes searching for Sanna again, and the two run away into a forest, where Sanna's dinosaur "parent" rescues her, but Tara is recaptured and the tribe prepare to burn him again. The coastline, however, begins to recede, and the tribe is attacked by giant crabs. As a tsunami looms overhead, Sanna arrives to save Tara and they escape with Kane and Ulido aboard a raft. Kingsor tries to command the water to heal in a last effort to appease his deities, only to be swept away. While Ayak is running towards the raft, she steps into a trap of quicksand and is sucked down to her death. As the waters calm, the four survivors stop to witness a lunar eclipse, left in awe by the creation of the Moon above them. Cast Victoria Vetri as Sanna Robin Hawdon as Tara Patrick Allen as Kingsor / Narrator Drewe Henley as Khaku Sean Caffrey as Kane Magda Konopka as Ulido Imogen Hassall as Ayak Patrick Holt as Ammon Carol Hawkins as Yani Production Writing Director Val Guest's screenplay was based on a treatment by J. G. Ballard (author of Empire of the Sun). But like Hammer's other prehistoric films, When Dinosaurs Ruled the Earth anachronistically portrays the dinosaurs of the Mesozoic Era from about living alongside Homo sapiens of the Late Quaternary Period (±200,000 years ago). The film's characters use a language that was specially written for the film, albeit of only a dozen words or so, a frequent one being "neekro", which means "kill", and also "akita", which is heard many times. Special effects The effects unit at Bray Studios was used on the production. The stop-motion animation creature effects were created by Jim Danforth, assisted by David W. Allen and Roger Dicken, with each model costing over $3,000 each on average. Allen made the crab puppet, which was made from a real crab shell, though Dicken modified it with horns and spikes
