You don't know about this dinosaur, you don't know what it was like, but I certainly do. He is close by, and he watches over all of us. I'm not sure where he hides, but he can see us, and if we ever become helpless and desperate, the dinosaur will come back to us and save us from tragedy and disaster, just as it did before on that doomed World War II battlefield we once faced.
— Masukichi Ikehata (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.
Godzillasaurus' name is a combination of "Godzilla" and the suffix -saurus, derived from the Greek saûros, meaning "lizard." As with Gorosaurus and Titanosaurus, the "saurus" part of Godzillasaurus' name uses the less common Japanese spelling ザウルス (zaurusu), using the voiced character ザ (za). Shinji Nishikawa's concept art for the creature, however, spells it as ゴジラサウルス (Gojirasaurusu). Though the creature's official trademarked name is Godzillasaurus, some Japanese sources offer the alternate spellings of Godzilla-Saurus and Godzilla Saures. In Godzilla vs. King Ghidorah, the Futurians refer to the Godzillasaurus on Lagos Island as the Dinosaur of Lagos Island (ラゴス島の恐竜. In Omni Productions' English dub of Ragosutō no Kyōryū)Godzilla vs. Mechagodzilla II, BabyGodzilla is called a "Godzillasaur" rather than a Godzillasaurus.
According to concept artist Shinji Nishikawa, Godzilla was originally written to be a Tyrannosaurus rex prior to being mutated in Godzilla vs. King Ghidorah. Nishikawa prepared concept art of the dinosaur, but said that he couldn't accept the idea that Godzilla was mutated from a Tyrannosaurus. Instead, he came up with the idea for the Godzillasaurus and submitted concept art of it to Toho, leading to its inclusion in the film. At least one piece of concept art was also known to have been created by artist "Hurricane" Ryu Hariken. Godzillasaurus was portrayed by suit actor Wataru Fukuda, and his suit was created by Fuyuki Shinada and his company buildup Co., Ltd. In addition to the suit, close-up models of the Godzillasaurus' flesh and the tip of his tail were also constructed. Originally, Fukuda was meant to portray King Ghidorah instead of the Godzillasaurus, but was too small to wear the Ghidorah suit and was assigned to the smaller Godzillasaurus suit instead.

An early draft for Godzilla vs. Mechagodzilla II called for an opening sequence set in the Cretaceous period which featured a battle between a Godzillasaurus and Pteranodon, foreshadowing Godzilla's eventual encounter with Rodan. According to screenwriter Wataru Mimura, this scene was ultimately cut from the film for budgetary reasons.
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 possesses 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. Godzillasaurus is also shown to possess tear ducts when BabyGodzilla is seen crying when Azusa Gojo is forced to leave him behind.
According to godzilla.com, the official English-language Godzilla website, Godzillasaurus is omnivorous. In Godzilla vs. Mechagodzilla II, Professor Hiroshi Omae suggests that it is possible Godzillasauruses acted as brood parasites, laying their eggs in the nests of other species, due to the presence of BabyGodzilla's egg in a Pteranodon nest.
A Godzillasaurus lived on Lagos Island 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 artillery. 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. However, they failed to prevent Godzilla's creation, as a nuclear submarine accident in the Bering Sea provided the energy to turn the Godzillasaurus into Godzilla in this new timeline.

Another Godzillasaurus, named BabyGodzilla, was found in Rodan's nest on Adonoa Island in Godzilla vs. Mechagodzilla II. This infant Godzillasaurus was raised by U.N.G.C.C. scientists and imprinted on a scientist named Azusa Gojo as its mother, but was adopted by Godzilla after Azusa was forced to part ways with him. BabyGodzilla lived with his new adopted father on Baas Island, where he was exposed to his radiation and mutated into LittleGodzilla. As a toddler, LittleGodzilla was already much larger than the seemingly adult Godzillasaurus found on Lagos Island. After living on the island for a year, LittleGodzilla was exposed to a massive dose of radiation when uranium deposits on Baas Island ignited and exploded, mutating him into a sub-adult Godzilla dubbed Godzilla Junior. Godzilla Junior attempted to return to his birthplace on Adonoa Island, but was lured to Tokyo so that Godzilla would follow and battle the monster Destoroyah. Eventually, Junior was killed by Destoroyah, and the grieving Godzilla fought and killed Destoroyah with the help of G-Force. When Godzilla died of a catastrophic meltdown in his heart, the radiation he released was absorbed by Junior, reviving him and transforming him into a new Godzilla.
Despite its relatively small size in comparison to other kaiju, the Godzillasaurus that would eventually become Godzilla displayed a high amount of strength and endurance. Small arms 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.
As is shown in Godzilla vs. Mechagodzilla II, Godzillasauruses seem to be telepathic, as BabyGodzilla can contact his father and Rodan telepathically. Since at this point BabyGodzilla had not yet been mutated, it is possible that all Godzillasauruses naturally have this ability as a form of communication.
After Doctor Oniyama, with the assistance of his 25th century descendant, revived Anguirus as an Ankylosaurus, he forcibly-devolved Godzilla into a Godzillasaurus using KIDS. After Godzilla fought the Ankylosaur, the two Oniyamas fired a syringe containing modified DNA from KIDS at the Ankylosaurus, mutating it into the much larger Anguirus. The un-mutated Godzilla seemingly stood no chance against Anguirus, who leapt into the air and crushed the Godzillasaurus beneath him. For a few moments, all seemed lost, until the devolution wore off and Godzilla re-emerged from the ground.

- In an in-universe 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 Mosasaurus.
- An actual species of dinosaur was named Gojirasaurus quayi in homage to Godzilla himself. However, Gojirasaurus bears little resemblance to its movie counterpart, and is a dubious genus.
- While virtually all sources agree on the Godzillasaurus' height of 12 meters, concept art for the creature created by "Hurricane" Ryu Hariken lists a height of "8 meters (or 12 meters)" with a chart showing him standing at 8 meters. Additionally, due to a misprinting, the Godzillasaurus is given the Dorats' height of 30 centimeters in the publication Toho Special Effects Movie Complete Works (p. 226).
- Though generally accepted to weigh 60 metric tons, some sources give the Godzillasaurus a weight of just 8 metric tons, such as Godzilla Completely Deciphered (p. 107) and Shin Godzilla Walker: The New Legend of the King of the Monsters (p. 70). In concept art of the Godzillasaurus created by "Hurricane" Ryu Hariken, its weight is listed as 5 metric tons. Additionally, due to a misprinting, the Godzillasaurus is given the Dorats' weight of 800 grams in the publication Toho Special Effects Movie Complete Works (p. 226).
