Triceratops prorsus

Triceratops horridus is a large herbivorous species that encounters itself high in the food web of Mesos. They can be found in herds or solitary all through the eastern zone of the continent all year and seasonally migrate west for reproduction purposes.

This animals become easily aggressive when provoked, and should never be bothered or harassed.

Basic Information

Anatomy

Triceratops prorsus reaches lengths of 8 to 9 meters from beak to tail and up from 2.5 to 3.5 meters in height to their shoulder in both genders.

Their most distinguishable trait are their heads. They have a large skeletal frill in the rear of their skulls, adorned with epoccipitals which are more pronounced in males. Triceratops prorsus have three horns: two large horns of around 1 meter long which are on top of their eyes and curve down and one smaller horn of around 20 to 50 centimeters on top of their nostrils pointing vertically.

Triceratops prorsus are muscly, sturdy animals. Their body is quite spherical and have a good capacity to sustain fat. They have strong arms with three hooves each and strong legs and short strong legs with four hooves each, with their fingers pointing out and away from the body. They are quadrupedal, walking with their four limbs straight from the ground. However, when faced with a threat, they sprawl their arms with an angle from their thorax to lower their heads and expose their horns. Their skin is tough and thick. The skin is mainly scaly and could reach thicknesses of 10 centimeters. It possessed osteoderms along the back and tail. Triceratops prosus had quill-like scales on their backs, increasing on size as they reached the tail.

Genetics and Reproduction

To copulate, a bull needs to be paired to a cow. If a bull is unpaired, by the beginning of fall, it will try to pair with a cow of its preference.

At the end of fall, Triceratops couples copulate in an action called a "cloacal kiss". They will make their cloacas touch each other and the male will impregnate the female.

When winter arrives, Triceratops prorsus migrate to the south of the Selvada, where the height of the hills gives them terrain for nesting when the floods arrive at the north. There, females make nests and lay around 3 to 6 eggs. Eggs hatch by the end of spring. Unpaired females tend to reproduce with the patriarch before marching east.

Growth Rate & Stages

Hatchlings have a very spherical body. Their legs barely let them discover around the nest. They possess very small horns and big eyes relative to their bodies. Mothers take active care of them. Juveniles differ from hatchtlings mainly on their size and activity. They become more vocal and show the first signs of dominance and personality.

A youngster passes from juvenile to subadult when they show the first signs of sexual dimorphism. Males start showing distinct colors on their frills while females show non. They can also be easily difference from other stages by their horns which grow long and upwards. Male Triceratops prorsus reach sexual maturity at 4 months old and females reach fertility at 8 years old. However, bulls tend to reproduce for the first time by 5 years old and females by 10 years old. Adults can be easily distinguished from other stages for their long curve down horns and their very remarked frill. They become sexually active and protect the herd from predators.

Dietary Needs and Habits

Triceratops prorsus are low foraging herbivores. They eat low growing plants like bushes, small ferns and small trees. They use their solid beaks to cut the hard trunk of plants and use their molar teeth to chew on it enough for it to be digested. When a tree is too high to reach yet is isn't too big, they can knock the tree down by pushing it with their heads.

Additional Information

Social Structure

Triceratops live typically in herds lead by a matriarch and guarded by a patriarch. Other bulls follow the herd from a far, using their sense of smell to keep their track.

Geographic Origin and Distribution

Triceratops prorsus can be found all around Selvada all year long. They only become absent in certain locations that flood too much for them to stand on ground.

Perception and Sensory Capabilities

Triceratops possess a really poor vision and hearing. They can see objects afar but cannot distinguished well between what they are until close (around 100 meters away). However they possess a good sense of smell which lets them recognize their environment even if they can't distinguish it with their eyes.

Symbiotic and Parasitic organisms

Some species of ticks and other blood sucking parasites try living in Triceratops skin. However, their thick skin makes it hard for this animals to penetrate it and usually leave their hosts when they reach adult size.

Body Tint, Colouring and Marking

Their skin is generally dull in color in all of its body but in the frill. Triceratops prorsus have specially colorful frills which color varies a lot between individuals. Frills tend to be more brightly colored in males than females.
