Crushitan is a huge hypercarnivore found in forested areas all over the south of mainland Tudera. Famous for their huge keratin growths on head, that form a wide blunt horn. It is used in intraspecific combat but also cleaning and marking territory. The crushitan's "horned helmet" is supported by wide, dense skull that sits on top of muscular neck and robust torso. Such build not only gives strong head but a strong bite too. Bite of crushitan is comparable to the ones of derived tyrannosaurids, good at both killing prey and processing carcasses. As a species they lack specialization for specific type of prey and therefore hunt any animals that can sustain them. But due to crushitans having established territories that have prey often come from the same species, it is when crushitans can in fact develop sort of specialization. Although that is an individual variation in most cases as their offsprings never inherit specialization of their parents. Crushitans mark their territory by damaging trees using their horned helmet and also dung found all over the borders of their home.

A giant herbivore of huge warm wetlands found deep in south. Their actions define the current state of wetlands, and without them wetlands wouldn't be nearly as healthy and productive. Gnarly skin folds make them look scaly as a reptile, but those are in fact mammals. They need such weird skin mainly for thermoregulation and protection from predators. Though a lot of adult voloodars barely face any predation due to sheer size and fearsome tusks.

A giant nocturnal nautilus found in southern hemisphere oceans. Those are scavengers that move closer to water surface during night, feeding on any corpses they find. Dark mucus covering their shell and hood is an additional layer of defense against predation. While usually solitary, sometimes few individuals can be spot near each other.

Adults of this species are skittish grazers of seagrass and algae while juveniles live as parasites of huge marine reptiles.

One of the northern hemisphere large top predators. This giant reptile hunts mainly other marine tetrapods, using massive jaws to cause heavy bleeding. As their prey is often as dangerous as they themself are, spotted tyrathans can form small unorganized pods to minimize risk. Specifically in temperate pelagic waters, tyrathans are considered the top order carnivore.

Some specevo biomes concept doodles without context:

Igugong are sluggish herbivore marine reptiles found in some mangroves of IoRS. Different from their relatives their head shape is much more "normal" and can remind of herbivorous squamates, like iguana. They are generalist and feed on any plant material thatcan be find and processed. Front flippers have six, huge claw-like osteoderms that are used to hold leaves and fruits that igugong feed on. Their front flippers are flexible, especially when it comes to pulling limbs forward. Eyes are quite large and assist in locating food items that might fall from mangrove trees. Igugongs are not picky eaters but will prefer fresh plants over ones that are old or partly rotten. Mangroves lack huge predators due to lack of space but igugongs are still very skittish animals even considering they are the largest animal native here. When afraid they will swim close to the bottom of water. Then stay still and silent before whatever scared them is gone.
