Gojirasaurus

Godzillasaurus (ゴジラザウルス Gojirazaurusu) is a fictional species of theropod dinosaur that first appeared in the 1991 Toho Godzilla film, Godzilla vs. King Ghidorah.

In 1944, Japanese and American garrisons battling on Lagos Island during the Pacific War encountered a Godzillasaurus, which proceeded to attack and repel the American forces in order to defend its territory. The dinosaur later collapsed from injuries sustained in the battle, while the Japanese garrison paid their respects to the creature before departing. In a misguided attempt to erase Godzilla from history, a group of time travelers used the ship KIDS to teleport the wounded Godzillasaurus into the Bering Sea where they expected it would die far from nuclear testing. In the 1970's, a Soviet nuclear submarine crashed in the dinosaur's vicinity, the released radiation revitalizing it and transforming it into Godzilla. In 1994, a team of Japanese researchers recovered what seemed to be an intact Pteranodon egg from Adonoa Island and brought it back to Kyoto. To the scientists' surprise, the egg hatched into a Godzillasaurus, which was given the name BabyGodzilla. Professor Hiroshi Omae came to the conclusion Baby may have been a parasite egg laid in a Pteranodon nest by another Godzillasaurus. Baby was subsequently adopted by Godzilla, with prolonged exposure to his radiation gradually transforming him into another Godzilla.
