This screenplay by Ib Melchior and Ed Watson would have incorporated the monster footage from GODZILLA RAIDS AGAIN, but little else. Instead, the plot would be set in America (parts in Chinatown to explain Asian-style architecture), with the monsters turned into generic dinosaurs. The basic premise would still be the same (the two giant monsters fight, the "tyranosaurus" (Godzilla) would kill the other dinosaur (Angillas), then be buried under ice.
Below is an image of the suits specially created for the American scenes, which ultimately went unused.
