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 Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems.
The Pliocene is the epoch in the geologic time scale that extends from 5.333 million to 2.58 million years ago. It is the second and most recent epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene.
Falcons are birds of prey in the genus Falco, which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.
Hippopotamidae is a family of stout, naked-skinned, and semiaquatic artiodactyl mammals, possessing three-chambered stomachs and walking on four toes on each foot. While they resemble pigs physiologically, their closest living relatives are the cetaceans. They are formally referred to as hippopotamids.
A pika is a small, mountain-dwelling mammal found in Asia and North America. With short limbs, very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. The large-eared pika of the Himalayas and nearby mountains is found at heights of more than 6,000 m (20,000 ft), among the highest of any mammal.
The darters, anhingas, or snakebirds are mainly tropical waterbirds in the family Anhingidae, which contains a single genus, Anhinga. There are four living species, three of which are very common and widespread while the fourth is rarer and classified as near-threatened by the IUCN. The term snakebird is usually used without any additions to signify whichever of the completely allopatric species occurs in any one region. It refers to their long thin neck, which has a snake-like appearance when they swim with their bodies submerged, or when mated pairs twist it during their bonding displays. "Darter" is used with a geographical term when referring to particular species. It alludes to their manner of procuring food, as they impale fishes with their thin, pointed beak. The American darter is more commonly known as the anhinga. It is sometimes called "water turkey" in the southern United States; though the anhinga is quite unrelated to the wild turkey, they are both large, blackish birds with long tails that are sometimes hunted for food.
The buntings are a group of Old World passerine birds forming the genus Emberiza, the only genus in the family Emberizidae. The family contains 45 species. They are seed-eating birds with stubby, conical bills.
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOU adopted a consensus taxonomy of seven genera. The great cormorant and the common shag are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.
The common raccoon dog, also called the Chinese or Asian raccoon dog to distinguish it from the Japanese raccoon dog, is a small, heavy-set, fox-like canid native to East Asia. Named for its raccoon-like face markings, it is most closely related to foxes. Common raccoon dogs feed on many animals and plant matter, and are unusual among canids in that they hibernate during cold winters and can climb trees. They are widespread in their native range, and are invasive in Europe where they were introduced for the fur trade. The similar Japanese raccoon dog, native to Japan, is the only other living member of the genus Nyctereutes. Other names for the common raccoon dog include mangut, and neoguri.
Ostriches are large flightless birds. They are the heaviest living birds, and lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, with significant industries in the Philippines and Namibia. Ostrich leather is a lucrative commodity, and the large feathers are used as plumes for the decoration of ceremonial headgear. Ostrich eggs have been used by humans for millennia.
Hadar or Hadar Formation is a paleontological site 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.
Nyctereutes is a genus of canid which includes only two extant species, both known as raccoon dogs: the common raccoon dog and the Japanese raccoon dog. Nyctereutes first entered the fossil record 5.5 million years ago (Mya) in northern China. It was one of the earliest canines to arrive in the Old World. All but two species became extinct before the end of the Pleistocene. A study suggests that the evolution of Nyctereutes was influenced by environmental and climatic changes, such as the expansion and contraction of forests and the fluctuations of temperature and precipitation.
Nyctereutes donnezani is an extinct relative of the raccoon dog. It has been found in Spain Poland, Greece, and Turkey.
Ferrucyon is an extinct genus of omnivorous mammal of the family Canidae, which inhabited North America during the Pliocene, Blancan in the NALMA classification, from about 4.9 to approximately 2.6 Ma. The type species, F. avius, was originally interpreted as a relative of the modern crab-eating fox, and described as a species belonging to the genus Cerdocyon. Ruiz-Ramoni et al. (2020) reinterpreted it as a vulpine canid related to North American species Metalopex macconnelli, and to the Eurasian genus Nyctereutes. This reinterpretation necessitated removal of "Cerdocyon" avius from the genus Cerdocyon, and Ruiz-Ramoni et al. (2020) transferred it to the separate genus Ferrucyon.
Pliohyrax, is a genus of hyracoids. It grew to sizes greatly exceeding those of any living hyrax, though it was by no means the largest member of this family.
Suinae is a subfamily of artiodactyl mammals that includes several of the extant members of Suidae and their closest relatives – the domestic pig and related species, such as babirusas. Several extinct species within the Suidae are classified in subfamilies other than Suinae. However, the classification of the extinct members of the Suoidea – the larger group that includes the Suidae, the peccary family (Tayassuidae), and related extinct species – is controversial, and different classifications vary in the number of subfamilies within Suidae and their contents. Some classifications, such as the one proposed by paleontologist Jan van der Made in 2010, even exclude from Suinae some extant taxa of Suidae, placing these excluded taxa in other subfamilies.
The Japanese raccoon dog, also known as the tanuki, is a species of canid endemic to Japan. It is one of two species in the genus Nyctereutes, alongside the common raccoon dog, of which it was traditionally thought to be a subspecies.
Nurocyon is an extinct member of the dog family (Canidae) from the Pliocene of Mongolia. Nurocyon chonokhariensis is the only species in the genus. The teeth of Nurocyon show adaptations to an omnivorous diet, comparable to the living raccoon dog. The overall structure of the skull and dentition of Nurocyon are intermediate between the living genus Canis and the more primitive Eucyon.
Archaebalaenoptera is a genus of extinct rorqual known from late Miocene to Pliocene-age marine deposits of the Netherlands, northern Italy, and Peru.
Dolichopithecus is an extinct genus of Old World monkey that lived in Europe during the Late Miocene and Pliocene.
