Syndyoceras

Syndyoceras was a mammal that looked like modern-day deer. The male had two sets of horns. One set grew between its ears, while the other was just above its nose.

Syndyoceras was about the same size as the white-tailed deer. It grew to a height of three feet (one meter), a length of five feet (1 1/2 meters), and a weight of 130 pounds (59 kilograms). It had a light brown coat with areas of white beneath its neck and tail. The male Syndyoceras had two sets of bony growths, similar to horns. One set grew out from its forehead like those on a cow and the other set grew out just before its nose. The female did not have these growths. Syndyoceras had incisors, or teeth for cutting, on its lower jaw and two sharp canine teeth that jutted outside its mouth when closed. It also had tough molars, or teeth for grinding its food.

Syndyoceras was very picky about what it ate. It lived mainly on a diet of shrubby leaves and soft vegetation. Using large molars and a hard pad on the roof of its mouth, it ground its food until it was soft enough to swallow. Its rows of cheek teeth had sharp edges that helped the animal chew leaves and plants.

Syndyoceras did not have many ways of defending themselves against predators. The horns of the male Syndyoceras were too soft to be used as weapons. It may have used its sharp, canine teeth but probably relied on its swiftness and alertness to escape.

The male Syndyoceras was a solitary animal. This meant he did not like to live closely with other male Syndyoceras. During mating season, he fought with other males to win his territory, or area of land, and to attract a mate. Like deer today, Syndyoceras mated in the fall and gave birth to their young in early summer. The newborn Syndyoceras was born with a coat that helped it blend in with its environment and protected it from predators. A young Syndyoceras would stay with its mother for about a year before going off on its own.

Syndyoceras lived in the plains near the muddy banks of rivers where there was plenty of vegetation to eat. When feeding, the animal kept from sinking into the soft ground near the river by spreading its hooves.

Fossil remains of Syndyoceras have been found in Wyoming and Nebraska.
