Hyenas or hyaenas are feliform carnivoran mammals belonging to the family Hyaenidae. With just four extant species, it is the fifth-smallest family in the order Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems.
Dinofelis is an extinct genus of machairodontine, usually classified in the tribe Metailurini. It was widespread in Europe, Asia, Africa and North America from 5 million to about 1.2 million years ago. Fossils very similar to Dinofelis from Lothagam range back to around 8 million years ago, in the Late Miocene.
Homotherium is an extinct genus of scimitar-toothed cat belonging to the extinct subfamily Machairodontinae that inhabited North America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. It was one of the last surviving members of the subfamily alongside the more famous sabertooth Smilodon, to which it was distantly related. It was a large cat, comparable in size to a lion, functioning as an apex predator in the ecosystems it inhabited. In comparison to Smilodon, the canines of Homotherium were shorter, and it is suggested to have a different ecology from Smilodon as pursuit predator adapted to running down large prey in open habitats, with species of the genus also proposed to have engaged in cooperative hunting.
Diceros is a genus of rhinoceros containing the extant black rhinoceros (Diceros bicornis) and several extinct species.
Crocuta is a genus of hyena containing the largest extant member of the family, the spotted hyena (Crocuta crocuta). Several fossil species are also known, with the Pleistocene Eurasian cave hyenas either being regarded as distinct species or subspecies of the spotted hyena.
Hadar or Hadar Formation is a paleontological fossil site located in Mille district, Administrative Zone 1 of the Afar Region, Ethiopia, 15 km upstream (west) of the A1 road's bridge across the Awash River.
Ekorus ekakeran is a large, extinct mustelid mammal. Fossils, including largely complete skeletons, are known from the late Miocene of Kenya.
Adelphailurus is an extinct genus of metailurin machairodontine (saber-toothed) cat that inhabited western North America during the middle Pliocene. It is monotypic, containing only the species Adelphailurus kansensis.
Percrocuta is an extinct genus of hyena. It lived in Europe, Asia, and Africa, during the Miocene epoch.
Percrocutidae is an extinct family of hyena-like feliform carnivores endemic to Asia, Africa, and Southern Europe from the Middle Miocene through the Pliocene, existing for about 8 million years.
Mount Blanco is a small white hill — an erosional remnant — located on the eastern border of the Llano Estacado within Blanco Canyon in Crosby County, Texas. With Blanco Canyon, it is the type locality of the early Pleistocene Blanco Formation of Texas and Kansas, as well as the Blancan fauna, which occurs throughout North America. Mount Blanco is a Late Blancan age site, and is associated with other Late Blancan sites from Texas such as Red Light and Hudspeth local faunas from Hudspeth County, and the Cita Canyon fauna from Randall County.
Canis edwardii, also known as Edward's wolf, is an extinct species of wolf in the genus Canis which was endemic to North America three million years ago from the Late Blancan stage of the Pliocene epoch and was extinct by the end of the Irvingtonian stage of the Pleistocene epoch.
Canis lepophagus is an extinct species of canid which was endemic to much of North America during the Early Pliocene. It is notable because its lineage is proposed to have led to both wolves and coyotes.
Borophagus hilli is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the Late Miocene until the Pliocene.
Thalassictis is an extinct genus of terrestrial carnivore in the family Hyaenidae that lived in Asia during the Middle to Late Miocene and in Europe and North Africa during the Late Miocene.
Adcrocuta is an extinct genus of terrestrial carnivore in the family Hyaenidae that lived in Africa and Eurasia during the Miocene epoch.

Enhydriodon is an extinct genus of mustelids known from Africa, Pakistan, and India that lived from the late Miocene to the early Pleistocene. It contains nine confirmed species, two debated species, and at least a few other undescribed species from Africa. The genus belongs to the tribe Enhydriodontini in the otter subfamily Lutrinae. Enhydriodon means "otter tooth" in Ancient Greek and is a reference to its dentition rather than to the Enhydra genus, which includes the modern sea otter and its two prehistoric relatives.
Taowu is an extinct genus of machairodonts, a type of saber-toothed cat. It lived during the Early Pleistocene about 2.5 million years ago in East Asia. So far, only one skull is known, found in northern China. Based on this, a relatively small representative of the saber-toothed cats can be reconstructed, which only reached the size of a present-day leopard. In its dentition characteristics, it mediates between phylogenetic older forms such as Amphimachairodus and younger members such as Homotherium. The genus was scientifically described in 2022, but the find material was recovered as early as the 1930s.
