Holodistortia

**Holodistortia** (meaning "entirely misshapen") is a terraformed world larger than Earth within the Jigoku-system with the star Jigoku. It also has a moon called Meido. Holodistortia's atmosphere consists mostly of nitrogen and oxygen. Like the Earth, it has icecaps, and greenhouse gases for regulating the temperatures.

The planet is inhabited by fauna descended from somewhat obscure or underrated animals, with a few exceptions.

### Notable introduced animal species

* Unnamed basal lepospondyl
	+ Ancestor of the salamander-like urophorates, the eel-like anguillophidians, and the frog-like sinecaudates.
* *Caerorhachis bairdi*
	+ Ancestor of the paramniotes, amniote-like tetrapods closer to true amphibians (frogs, salamanders, *Eryops*, etc.) than they are to true amniotes (the last common ancestor of *Deinonychus antirrhopus* and *Smilodon fatalis*).
* *Sanctacaris uncata*
	+ Ancestor of the scalpects, which are known as Distortion insects as they are analogous to true insects, though they are closer to arachnids as they are chelicerates.
* Unnamed non-monotreme yinotherian
	+ Ancestor of many mammal lineages found here.
* Basal feliform
	+ Ancestor of the primate-like homofeliforms.
* Unnamed basal oxyaenodont
	+ Ancestor of the cat-like patrioleoniforms and the seal-like plototheriiforms.
* A genetically-modified aquatic fetus-like organism descended from *Homo sapiens*
	+ Ancestor of many aquatic and terrestrial animals.
* Unnamed basal treeshrew
	+ Ancestor of many tillodont and eulipotyphlan-like forms.
* Unnamed basal arctocyonian
	+ Ancestor of many somewhat bear-esque carnivores
* Unnamed basal mesonychian
	+ Ancestor of many carnivorous, omnivorous, and secondarily herbivorous forms (assuming that the ancestral ungulate was a herbivore).
* Unnamed basal ankyramorph parareptile
	+ Ancestor of the primochelydians, turtle-like parareptiles that live on many continents.
* Unnamed captorhinid
	+ Ancestor of the eucotylosaurs, lizard-like reptiles that have well-developed pineal eyes.
* Unnamed weigeltisaurid
	+ Ancestors of the daedalosaurs, flying reptiles with 'wings' derived not from forelimbs, but from novel rod-like bones controlled by modified abdominal muscles. As this form of flying is the least efficient as these rods lack joints, they have to flap rapidly and thus use up lots of energy. As such, they are nectarivores (energy) and scalpectivores\* (proteins, minerals, vitamins, etc) as those contain the energy needed for this lifestyle.
		- Scalpectivory is a term used for animals that eat scalpects as strictly speaking, scalpects are not true insects.
* Unnamed cyamodontoid placodont
	+ Ancestor of the planarmids, a clade of terrestrial and amphibious turtle-like reptiles and one of 3 tetrapod lineages on Holodistortia that have experienced "testudinization", a phenomenon where a tetrapod evolves a turtle-like physiology, including a shell composed of a carapace and usually a plastron, a typically small head and short tail.
		- The other 2 are some the basal sauropsid parareptiles and non-reptiliomorph paramniotes, though unlike them, the ancestral cyamodontoid already had a shell.
		- Testudinized lineages outside Holodistortia include the saurosphargids, other cyamodontoids, and of course true turtles distantly related to archosaurs.
* Unnamed tangasaurid
	+ Ancestor of a marine lineage known as the magnatatorians, fully-aquatic piscivores similar to ichthyosaurs and pliosauroids.
* Unnamed thalattosaurian
	+ Ancestor of a mostly marine lineage known as the archonatricids, fully-aquatic reptiles similar to plesiosauroids and mosasaurids. Unlike the magnatatorians, they are more varied in their diets, with some species being macropredators, piscivores, osteophages, molluscivores, crustaceovores, corallivores, and even herbivores.
* Unnamed allokotosaur
	+ Ancestor of the amcelites, medium-large desert/savanna herbivores that sometimes have buffalo-like humps used for fat storage as food tends to be somewhat sparse in those environments.
* Unnamed rhynchosaur
	+ Ancestor of the bathyfossorids, small to medium-sized strictly herbivorous fossorial reptiles that feed on tubers and bulbs, though they will eat surface plants in areas where there are very few predators above ground.
* Unnamed proterochampsian
	+ Ancestor of the fauxosuchids, medium to large semi-aquatic predators found all over Holodistortia. Despite all appearances, they are not closely related to actual crocodilians.
* Unnamed aphanosaur
	+ Ancestor of the horrendosaurs, a lineage of avemetatarsalian archosaurs similar in appearance to dated reconstructions of non-avian dinosaurs. As such, their lifestyles are varied though due to a nocturnal bottleneck causing them to lose colored vision, many of them are bland, earthy colors such as brown, reddish-brown and grey. They are distantly related to the pterosaurs and dinosaurs of Earth. A few have become fully aquatic animals.

* Unnamed basal poposaur
	+ Ancestor of the thermosaurs, a lineage of pseudosuchian archosaurs similar to theropods and ornithischian dinosaurs. They show a blend of traits found in dated-restorations of dinosaurs and up-to-date restorations of dinosaurs. They tend to be more colorful in appearance than the horrendosaurs.
* Unnamed lagerpetid
	+ Ancestor of the arborosaurs, the reptilian equivalent of mammals like squirrels and lemurs.
* Unnamed rugose coral
	+ Rugose corals are common reef-building organisms worldwide.
* Unnamed tabulate coral
	+ Ancestor of many reef-building organisms found on Holodistortia.
* *Opabinia regalis*
	+ Ancestor of the basal arthropod clade Proboscihelminthes, which contains velvet worm-like animals with five eyes, an "elephant trunk", and a true mouth underneath.
* Unspecified rudists
	+ Unique bivalve molluscs that are common reef-builders worldwide, typically have a colorful soft body in a strange shell.
* Unnamed therocephalian
	+ Ancestor of the crotalomustelids, a lineage of ancestrally carnivorous therapsids containing small, colorful, and venomous forms and large non-venomous forms (a few large forms have venom to take on herbivores far larger than them). Some have became omnivorous. Small forms can also spray venom from their mouths.
* Unnamed conodont
	+ Ancestor of many jawless fish species found on Holodistortia
* Unnamed myllokunmingiid
	+ Ancestor of the clade Paraichthyes, which contains algivorous and bottom-feeding forms.
* Unnamed hagfish
	+ Ancestor of the myxophores, aquatic (bottom-feeding) and terrestrial pseudo-lobopods (frugivores and carnivores) that can exude a toxic or suffocating slime when threatened. Terrestrial forms can also shoot out clumps of this mucus to restrain prey or blind predators.
* Thelodus parvidens
	+ Ancestor of the cetonavids, a family of small to mid-sized filter-feeders.
* Unspecified trilobites
* Unspecified holostean
	+ Ancestor of most Holodistortian jawed-fish.
* Unnamed rhenanid
	+ Ancestor of many stargazer and ray-like forms
* Unnamed arthrodire
	+ Ancestor of many shark-like forms
* Unnamed gondwanathere
	+ Evolved into the hoofed septentriungulates of the north.
* *Anomalocaris sp.*
	+ Ancestral to the swamp-dwelling sebecaridids found on a few remote locations.
* Unnamed archaeocyathan sponge
	+ Major reef-building organisms, ancestral to the neocyathans.
* Unnamed euthycarcinoid
	+ Ancestor of the gumonids, arachnid-like animals unrelated to arachnids as they are closer to insects, and the lignopediculans, woodlouse-like animals found worldwide.
* Unnamed thylacocephalan
	+ Many have become krill-like animals and the main component of ocean ecosystems, while others have evolved into predators and scavengers.
* Unnamed stomatopod
	+ Some have become terrestrial, living in trees and giving birth to small versions of themselves.
* Unnamed cyclidan
	+ Occupy crab-like niches on land and in water.
