Water Chevrotains were the only ruminant to survive the holocene since all the others were killed by the extinction or hunted down by the last humans. It only survived since it had the advantage of being excellent at hiding and having a more varied diet. The descendants of these resiliant creatures would rapidly diversify and fill all sorts of new niches. The calidocene chevrotains only live in Africa due to sea levels isolating the continent. Lets take a look at some of the more highly derived descendants.

The Tragulibara

Tragulibaras (Lamacervus spumaesus, scum-eating marsh-deer) are semiaquatic and live in the saltree forests, rivers, and lakes of the Adzanian islands. Tragulibaras are about as big as a capybara and weigh about 100 pounds. Tragulibaras much like their ancestors use the water to escape from predators and are very good swimmers. They are able to stay underwater for about 5 minutes and graze along the bottom. Unlike their ancestors, they have a fully developed 4 chambered stomach, smaller eyes due to being diurnal, and higher up and stronger front limbs. Their diet consists of algae, aquatic plants, and grasses. They have a stronger jaw and a larger skull than their ancestors. The canine teeth have reduced in length but are still used for fighting.

Tragulibaras are mostly solitary but are more open to being around each other, fights break out less and territorial boundries are very loose.

The Towertain

Towertains (foliumlappero longuscollum, long-necked leaf-lapper) are high browsers and reside in the central african rainforests. They are about 5 feet tall at the shoulder and have a back hump to help support its flexible 3 foot long neck. Their front quarters are slightly larger than their hind quarters. They have a fully developed 4 chambered stomach and stronger jaw much like their relatives. They have a longer snout with a 2 foot long prehensile tongue, this tongue allows it to reach higher and grab food. The Towertain's diet mostly consists of leaves and fruit. Towertains have a gestational period of one year and the young hit maturity at 1, they mate for life and die at age 20.

Towertains are mostly solitary but to come together once a year in groups of 100 in small clearings to mate. The towertains get each others scents and females select which males they want to mate with with. If the female selects 2 males, the males fight by smacking their necks against each other and biting each other with their blunt tusks, whoever gets knocked down first loses and might have a shot at mating next year.
