|— Allen, about Hyaenodon|
Hyaenodon (name meaning "Hyaena Tooth") is a genus of Hyaenodontidae that originated during the Late Eocene epoch in what is now Asia. Fast and vicious canine-like mammals that measured 6 meters long, these carnivores were as large as a rhinoceros and a stag. Among the apex predators of their time, they hunted and killed in packs.
In the episode "The Big, the Small, the Bad, & the Ugly", a small pack of Hyaenodon was brought back to the park from the Oligocene in Mongolia 25 million years ago. They reside in an enclosure in the desert exhibit of the park.
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.
Hyaenodon was a large, dog-like, territorial and predatory creature. Hyaenodon may appear to have had a smaller appearance compared to larger creatures, such as a Paraceratherium. However, these carnivorous mammals were the size of modern rhinos, standing 5–6 feet (1.6–2 m) tall, measuring around 20 feet (6 m) long, weighing a total of 500 kg, and were easily capable of killing a newborn Indricotherium calf, assuming they could get passed the mothers.
Despite their name, Hyaenodon was not at all related to modern-day Hyenas, and they were, by far, more dangerous. Hyaenadon had a bone–shattering force of over 1,000 pounds per square inch. In addition to being deadly carnivores, they were also significantly fast and agile jumpers, able to quickly jump the length of a wide stairway to intercept fleeing prey.
Behavior & TraitsEdit
Hyaenodon was an apex predator, among the top predators of their environment. This animal preyed on the bizarre group of animals called Chalicotherium, 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.
Hyaenodon were stalkers, preferring to spy on and stalk their prey from among cover and shadows, then abruptly leap in for the kill. Hyaenodon apparently lived in very close family units and had fierce parental instincts; mother Hyaenodon would follow and try to stay close to their pups wherever they went, ruthlessly attacking and killing any and all animals that could potentially threaten the young, while the father Hyaenodon would guard the family unit's current surrounding area.
- 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, coyotes, and hyenas), cougar, wolf howls, leopard, and bear roars.
