This is Hyaenodon. Despite the name, these are not relatives of Hyenas. They are more dangerous by far.
— Allen, about Hyaenodon

Hyaenodon (name meaning "Hyaena Tooth") is a genus of Hyaenodontidae that originated during the Late Eocene epoch, lived through the Oligocene epoch and up until to the Early Miocene epoch in what is now Mongolia. Fast and vicious dog-like carnivorous predatory mammals that were as large a rhinos, these were among the apex predators of their time.

FactsEdit

Era & DiscoveryEdit

Hyaenodon first appeared in the Late Eocene period, about 42 million years ago, and lived during the Oligocene to Miocene period, over 25 to 15 million years ago. They were among the apex predators in their environment, often rivaled by the prehistoric hogs Entelodon. Hyaenodon was first discovered in 1838.

Physical AttributesEdit

Hyaenodon were large, dog-like, territorial and predatory creatures. Despite their name, Hyaenodon was not at all related to modern-day Hyenas, but they were by far more dangerous.

Next to a large animal like a Paraceratherium, Hyaenodon may have had a smaller appearance, however these carnivorous mammals were the size of modern rhinos, standing 5–6 feet (1.6–2 meters) tall, measuring around 20 feet (6 m) long, weighed a total of 500 kg, and were easily capable of killing an Indricotherium calf, if they could get passed the mothers. Hyaenadon had a bone–shattering force of over 1,000 pounds per square inch.

Behavior & TraitsEdit

Hyaenodon was an apex predator, among the top predators of their environment. This animal preyed on the bizarre group of animals called Chalicotheres, newborn or juvenile Paraceratherium, bear-dogs and a large, omnivorous relative of pigs and wild boars, the Entelodon. Its sheer size and meat-shearing teeth would make a deadly combination, making it an efficient and successful predator. It would also hunt cooperatively with other members of its kind. However, like most other early carnivorous mammals, Hyaenodon wasn't the brightest of animals.

TriviaEdit

  • It is coincidental that Hyaenodon has lived the same amount of time as hyenas, both being 21 million years.
  • The sound effects for Hyaenodon are that of canines (dogs, wolves, hyenas), cougar, leopard, and bear roars.
