Dinosaucers

On Reptilon, a twin planet to Earth, dinosaurs never became extinct, but evolved into two races of highly intelligent space travelers - the Dinosaucers and the Tyrannos. The desperate Dinosaucers have arrived on Earth seeking new energy sources. Tyrannos, however, share nothing and are determined to conquer Earth. It's up to four kids and the Dinosaucers to outmaneuver and outwit the Tyrannos.
