The Godzillasaurus is different from other theropods because its posture is more upright like a human, and it drags its tail on the ground, much like older theropod reconstructions. At 12 meters in height, it is much larger than any other theropod species, probably due to its erect posture. It has a smaller head than a real theropod, and has a double-row of teeth, much like a shark. The Godzillasaurus species is also different from other theropod dinosaurs due to the fact that it contains a second, or "sacral", brain located in its hip to control lower body functions, like how the Stegosaurus was mistaken to have had a second brain.
As is shown in Godzilla vs. MechaGodzilla 2, Godzillasauruses seem to be telepathic, as Baby Godzilla can contact his father. However, it is unknown if an unmutated Godzillasaurus would have this ability.
The Godzillasaurus lived on Lagos Island in Godzilla vs. King Ghidorah, and was attacked by American soldiers during World War II. This was observed by some of the Futurians and a group of people from the present that had traveled back in time to remove Godzilla from history. The Godzillasaurus fought off the Americans, seemingly 'defending' a bastion of Japanese soldiers who were on the island at the time, but was gravely wounded after multiple naval ships bombarded it with shells and missiles. Badly injured, the Godzillasaurus fell to the ground. After the Japanese soldiers paid their respects and left, the Futurians transported the injured dinosaur to the Bering Sea, thinking that they had successfully altered the present day. However, this was not to be the case, as a nuclear submarine crash in the Bering Sea provided the energy to turn the Godzillasaurus into Godzilla, thus preventing the timeline from changing.

Another Godzillasaurus, Baby Godzilla, is found in Rodan's nest in Godzilla vs. MechaGodzilla 2. This one seems to have been affected by nuclear radiation as well, considering the fact that when he was Little Godzilla in Godzilla vs. SpaceGodzilla, he was bigger than the seemingly adult Godzillasaurus.
Despite its relatively small size, the Godzillasaurus that would eventually become Godzilla displayed a high amount of strength and endurance. Small arm's fire and even rocket launchers were unable to damage him, and only barrages from several battleships were the only things strong enough to draw blood and weaken it.

Godzillasaurus, the King Dinosaur
A relic species of an ancient living being that once roamed all over the northern hemisphere. It is suspected that a living organism on the Island of Lagos in the Marshall Islands in the Pacific Ocean was later transformed into Godzilla. Though omnivorous and gentle, it has a habit of bravely confronting adversaries who dare step foot in its territory. Accounts of it repulsing advancing U.S. G.I.s from the island during the Pacific War endure to this very day.
Originally, the production team planned to have a Tyrannosaurus rex turn into Godzilla. However, this was shifted to the Godzillasaurus concept at the recommendation of the designers.

- In "Godzilla: A History," a book about Godzilla made by Kenichiro Terasawa, the main character of Godzilla vs. King Ghidorah, one of Terasawa's theories about how Godzilla came to be was that he was mutated from a whale, or kujira, that had Godzilla's dorsal plates.
- An actual species of dinosaur was named the Gojirasaurus, in homage to Godzilla himself. However, this "Godzillasaurus" bears only a slight resemblance to its movie counterpart, and is a dubious genus - which means that it may be a different type of dinosaur altogether.
- It is possible that Godzillasaurus is related to Therzinosaurus as it may be also a plant eater despite having sharp teeth (this is proven as of Baby Godzilla's diet). It is also possible that it is not a theropod at all and is instead a species of neo-prosauropod. This would explain its upright stance (some semi-bipedal prosauropods stood like this), its small head, its sacral brain and that it seems to be at least partially herbivorous.
- However, in deleted scenes from Gojira, Godzilla vs. Biollante and Godzilla vs. Destoroyah, Godzilla and Godzilla Junior were seen eating meat (cows, the unmade monster Deutalios, and whales, respectively). This could be an indication that the diet of Godzillasaurus is omnivorous or even completely carnivorous, though this could be because of them being mutated and thus needing an appropriate change in their diets.
- According to an interview with special effects designer Shinji Nishikawa, Godzilla was originally written to be a tyrannosaurus prior to being mutated. Nishikawa, however, said he couldn't accept the idea that Godzilla was mutated from a tyrannosaurus, so he came up with the idea for the Godzillasaurus and submitted concept art of it to Toho, who put it into the script for Godzilla vs. King Ghidorah.
- In Legendary Pictures' Godzilla, Godzillas were giant amphibious reptiles that evolved when Earth had ten times more radiation than it has today.
