Return of the Dinosaurs

A huge mysterious comet aiming straight for earth barely misses a collision. It's gravitational pull causes tidal waves, exploding mountains and huge earthquakes. Leaving the earth broken and destroyed, up from the depths come creatures of another time. Earth has returned to the age of tangling jungles, sweaty swamps and ancient monsters who once again roam the land, terrorizing all who are in their way. But something is wrong - the climate suddenly changes and the dinosaurs start dying. What can be done? Quickly all nations unite and a 'Dinosaur Patrol' is formed to capture and protect these misplaced creatures. CAN THEY DO IT?
