Hyaenodon ("hyena-tooth") is an extinct genus of carnivorous placental mammals from extinct tribe Hyaenodontini within extinct subfamily Hyaenodontinae (in extinct family Hyaenodontidae), [19] that lived in Eurasia and North America from the middle Eocene, throughout the Oligocene, to the early Miocene.

Hyaenodon, extinct genus of carnivorous mammals that first appeared in the fossil record about 42 million years ago during the middle of the Eocene Epoch and persisted until about 25 million years ago near the end of the Oligocene Epoch. The genus, in the order Creodonta, contained about 30 species.

Hyaenodonta (" hyena teeth") is an extinct order of hypercarnivorous placental mammals of clade Pan-Carnivora from mirorder Ferae. [6][7] Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe [8] and persisted well into the late Miocene. [9]

2012年12月29日 · Hyaenodon was the top predator of its day with the larger forms dominating the landscapes throughout the Oligocene periods.‭ ‬Key to this success was the large head that compared to today‭’‬s animals looks too large to fit upon the body.‭ ‬Indeed the neural spines of the forward dorsal vertebrae are enlarged to allow for an increased surface are...

2024年5月27日 · Hyaenodons are ancient carnivorous mammals that ruled the land in their day. The Hyaenodon was one prolific genus that lived in Eurasia and North America. Over 30 species within the genus showed the diversity and evolution of these animals. With features and behavior similar to modern-day hyenas, they actually weren’t related to hyenas at all.

2019年1月30日 · An in-depth profile of Hyaenodon, including this prehistoric mammal's characteristics, behavior, and habitat.

Hyaenodon was a genus of carnivorous mammals that lived in the Eocene and Oligocene epochs, between 56 million to 34 million years ago. These ancient predators roamed the open plains and woodlands in search of prey. Fossil records show that Hyaenodon lived in North America, Europe, Africa, and Asia.

Hyaenodontidae - The last surviving family of the carnivorous order of mammals called Creodonta, hyaenodons are best described as large, archaic predatory mammals that were widely and geographically distributed during the early Cenozoic.

Superficially doglike, Hyaenodon is quite chunky and robust. It has a short neck and a long, narrow skull. Its jaws are built for bone-crushing. Interestingly, as a Hyaenodon ages, its molars rotate inwards, keeping the teeth sharp. Its senses are well-developed, befitting an arch predator.
