Dinorattus ("terrible rat" in Latin) was a carnivorous rodent that lived during the late Postanthropocene (approximately 25 million years after present). It hunted small to medium-sized animals in packs, similar to wolves, and raised its young in burrows. It would have shared large portions of it's habitat with another large rodent, Brontomus.

DescriptionEdit

Dinorattus was a relatively small carnivore, about the size of a sheep. It had two sharp canine teeth that it used to bleed it's prey to death, in a manner similar to saber-toothed cats. These teeth developed from the front teeth of rodents, and were continually growing, which presented an evolutionary advantage.

It also possessed a furry tail that it used to signal to other individuals during hunting and social interaction.

Additionally, it possessed strong forelegs that it used to dig burrows, jump and hold on to prey, and dig out the burrows of small animals.

BehaviorEdit

The behavior of Dinorattus was very similar in many aspects to that of modern-day wolves. It hunted in packs with a dominant breeding pair and up to 13 subordinate individuals.

HuntingEdit

Dinorattus hunted in packs, much like a present-day wolf or lion. Due to the large size of it's packs and it's ability to jump, it was able to hunt animals as big as Posthippius, a horse the size of a kodiak bear. It used it's sharp canine teeth to sever large arteries in its prey, causing it to die of blood loss. It generally hunted large to medium-sized animals as a group, often corralling the animal into a group of waiting hunters. Dinorattus, however, was also fast enough to prey on small animals such as gazelles, small burrowing animals, and lizards.

ReproductionEdit

Dinorattus bred during the winter or dry season, depending on what latitude it lived at. Unless prey was especially abundant, only the dominant breeding pair bred.

Pups were born in early spring and nursed in a sheltered, hidden burrow by various females of the pack. Young began leaving the burrow at about three weeks of age, and older pack members began tutoring the pups in hunting techniques at six weeks. By this time, the young were generally about 3.5 feet long and weighed about 20 pounds.

Young Dinorattus reached sexual maturity at about 2 years, at which point females began breeding. At that point, males left the pack to join other packs or start packs of their own.
