I also have an evolutionary bio on them on my Deviantart (https://www.deviantart.com/godzillaloui ... -959980678), which describes how the Godzillasaurus genus evolved from Finagosaurus, a Late Cretaceous genus of theropods that evolved from Acrocanthosaurus atokensis.
Now, here’s where we get into the intelligence of the Godzillasaurus Maximus, for the following is from an ecology section on my WIP document on the species:
Additionally, according to my doc on my world’s take on Godzilla himself, Godzilla is “smarter than the average human, but not as smart as the smartest human.”All Godzillasaurus Maximus live in rather advanced societies, which are referred to as tribes. When a new tribe is being formed, the males make room for nesting grounds by tearing down several trees in large areas while the females find mates. The females will then dig out nests to lay their eggs in, with most of the males leaving the nesting grounds to form packs of 3 or 4 individuals to hunt. The rest of the males will stay behind to protect the eggs alongside the females. When the eggs hatch, the hatchlings will stay with their mothers between 9 and 10 years, after which they begin to fulfill the same roles their parents filled.
Within every tribe of Godzillasaurus Maximus, there is a pair that are at the top of their tribe’s hierarchy, consisting of an Alpha Male and Female. Between 9 and 10 years after their first clutch of eggs hatch, the strongest male offspring of the Alpha Male and Female’s first clutch will become the new Alpha. Usually, the title of ‘strongest’ goes to the offspring who can create the longest lasting plume of fire breath, though this can vary between tribes.
Though extremely territorial, tribes of Godzillasaurus Maximus will sometimes start turf wars with each other, similar to meerkats. However, they are known to avoid these conflicts by a variety of means.
Given all this information, how believable is the evolution of such intelligence, and what could some potential evolutionary catalysts be for such intelligence?
(Also, I know I said ‘fire breath’, which is contradictory of what Godzilla’s atomic breath is: a form of thermonuclear plasma shot out of the mouth as a laser-like beam. But Maximus aren’t Kaiju, they’re titanfuana. When exposed to enough thermonuclear radiation, their fuel source changes from a limited amount of methanol gained from diet to allow them to fire a more conventional beam of nuclear plasma.)
