Anomalotheria

Anomalotheres (  anomalous beasts  ) are four-limbed life-forms constituting the superclass Anomalotheria. Anomalotheres evolved from a group of  animals  (not biologically animals but yeah) known as the anomalopods which, in turn, evolved from ancient anomalotheriformes around 390 million Corian years ago in the middle Novacorian period; their forms were transitional between 6-legged anomalotheriformes and the four-limbed anomalotheres. The first anomalotheres appeared by the late Novacorian, 367.5 million Corian years ago. The specific aquatic/semiaquatic ancestors of the anomalotheres and the process by which they colonized Coria 4UKM's land after emerging from water remains unclear. The change from a body plan for breathing and walking on the seabed to a body plan enabling the animal to move on land is one of the most profound evolutionary changes known. The first anomalotheres were primarily semi-aquatic. Modern aoosaccoids(without egg-bags), which evolved from earlier groups, are generally gliding swamp creatures; the first stage of their lives is as caterpillar-like larva, and later stages are partly terrestrial and partly aerial. However, most anomalothere species today are oosaccoids, most of those are terrestrial anomalotheres whose branch evolved from earlier species about 340 million Corian years ago (crown amniotes evolved 318 million Corian years ago). The key innovation in oosaccoids over aoosaccoids is giving birth or laying egg sacs(there are 300-18 eggs inside one, the less eggs means the more derived, also the babies eat each other inside the sac, so only 4-3 hatch and live).

Oosaccoids began to dominate and drove most aoosaccoids to extinction. One group of oosaccoids diverged into the teratognaths, which includes all species of neoteratognaths and extinct relatives; while another group diverged into the galactognaths and their extinct relatives. Oosaccoids include the species that further evolved for flight, flying galactognaths.

Some anomalotheres, such as the tatzelwurms, have only two feet, because the other two were lost through further speciation and evolution; some have only concealed vestigial bones as a remnant of the limbs of their distant ancestors. Others returned to being amphibious or otherwise living partially or fully aquatic lives, the first during the Purpuriferous period, others as recently as the Holozoic.

Anomalotheres have numerous anatomical and physiological features that are distinct from their aquatic ancestors. These include the structure of the jaw and teeth for feeding on land, limb girdles and extremities for land locomotion, lungs for respiration in air, a heart for circulation, and eyes and ears for seeing and hearing in air.
