Description
Monāku Ōkoku, or the "Hollow Earth" as it has been nicknamed, is a enormous subterranean cavern found under the Atlantic ocean. With a size comparable to Australia, it is the largest subterranean structure in Earths history. It is thought that this cavern was easily accessible till some point in the Triassic Period, as the world is inhabited by many species of large Arthropods, Stem-Mammals, Placoderms, Pterosaurs, Early forms of Dinosaurs, Temnospondyls, and many other extremely ancient groups of animals which, in their isolation, survived and evolved into many different forms. unseen in the fossil record. The ceiling is covered by a continent sized colony of microorganisms, making it the largest colony of living things on the planet. These microorganisms feed upon the heat produced by the magma surrounding the cavern and using said energy to produce a orange photosynthetic glow, which is how life exists here at all. These microorganisms also respond to the Earth, Moon, and Suns rotation. As a result they change color every 20 hours to a dimmer bluish-green glow, creating a 40 hour "Day-Night Cycle". Much of the flora or coral is bioluminescent, creating a glow across the darkened world at night.

So for those of you that don’t know what this is, this is for a Speculative Evolution project of mine. Basically, it’s taking the concepts of Legendary Pictures Monsterverse, and taking them in an ultra scientific setting. Making a realistic “Hollow Earth” full of ancient creatures. Obviously none will be building sized like their science fiction counterparts, as I’m making them into genuine animals instead.
Credit to this map goes to The Cryptobiologist on discord, who made it for me as at the time of writing this paragraph I’m in the hospital with no computer access.
So, any questions or curiosities?
