Proteles is a genus of distinctive hyenas which contain the aardwolf (Proteles cristatus) and its close fossil relatives. [1] It is the only extant genus of the subfamily Protelinae.
While the oldest fossils definitely belonging to Proteles date back to the Pliocene, material from the Miocene dating to around 10 million years ago has been suggested to belong to the genus, which would significantly increase its temporal range. [2]
It has been suggested that the Proelinae subfamily may actually be an offshoot of the "running hyenas" (such as Lycyaena ) who adapted to an insectivorous diet due to increased competition from canines and felines. [3]
The aardwolf is an insectivorous hyaenid species native to East and Southern Africa. Its name means "earth-wolf" in Afrikaans and Dutch., termite-eating hyena, based on its habit of secreting substances from its anal gland.
Carnivora is an order of placental mammals that have specialized in primarily eating flesh, whose members are formally referred to as carnivorans. The order Carnivora is the sixth largest order of mammals, comprising at least 279 species on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. These mammals have a large array of diverse body plans with a wide diversity of shapes and sizes.
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.
Homininae, is a subfamily of the family Hominidae (hominids). This subfamily includes two tribes, Hominini and Gorillini, both having extant species as well as extinct species.
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.
The piculets are a distinctive subfamily, Picumninae, of small woodpeckers which occur mainly in tropical South America, with just three Asian and one African species.
Gavialidae is a family of large semiaquatic crocodilians with elongated, narrow snouts. Gavialidae consists of two living species, the gharial and the false gharial, both occurring in Asia. Many extinct members are known from a broader range, including the recently extinct Hanyusuchus. Gavialids are generally regarded as lacking the jaw strength to capture the large mammalian prey favoured by crocodiles and alligators of similar size so their thin snout is best used to catch fish, however the false gharial has been found to have a generalist diet with mature adults preying upon larger vertebrates, such as ungulates.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
Dipterocarpaceae is a family of flowering plants with 22 genera and about 695 known species of mainly lowland tropical forest trees. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. The greatest diversity of Dipterocarpaceae occurs in Borneo.
The Hominini (hominins) form a taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: Homo (humans) and Pan, but in standard usage exclude the genus Gorilla (gorillas), which is grouped separately within subfamily Homininae.
Pachycrocuta is an extinct genus of prehistoric hyenas. The largest and most well-researched species is Pachycrocuta brevirostris, colloquially known as the giant short-faced hyena as it stood about 90–100 cm (35–39 in) at the shoulder and it is estimated to have averaged 110 kg (240 lb) in weight, approaching the size of a lioness, making it the largest known hyena. Pachycrocuta first appeared during the late Miocene. By 800,000 years ago, it became locally extinct in Europe, with it surviving in East Asia until at least 500,000 years ago, and possibly later elsewhere in Asia.
Lybiidae is a family of birds also known as the African barbets. There are 42 species ranging from the type genus Lybius of forest interior to the tinkerbirds (Pogoniulus) of forest and scrubland. They are found throughout sub-Saharan Africa, with the exception of the far south-west of South Africa.
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats, hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia.
Alopecocyon is a fossil genus of ailurid belonging to the subfamily Simocyoninae. It has two species, Alopecocyon goeriachensis and Alopecocyon getti. It is based on fragmentary fossils dating to the middle Miocene of both Europe and Asia.
The Viverrinae represent the largest subfamily of the Viverridae comprising three genera, which are subdivided into six species native to Africa and Southeast Asia. This subfamily was denominated and first described by John Edward Gray in 1864.
The tribe Bovini or wild cattle are medium to massive bovines that are native to Eurasia, North America, and Africa. These include the enigmatic, antelope-like saola, the African and Asiatic buffalos, and a clade that consists of bison and the wild cattle of the genus Bos. Not only are they the largest members of the subfamily Bovinae, they are the largest species of their family Bovidae. The largest species is the gaur, weighing up to 1,500 kg (3,300 lb).
Eogavialis is an extinct genus of eusuchian crocodylomorph, usually regarded as a gavialoid crocodylian. It superficially resembles Tomistoma schlegelii, the extant false gharial, and consequently material from the genus was originally referred to Tomistoma. Indeed, it was not until 1982 that the name Eogavialis was constructed after it was realised that the specimens were from a more basal form.
Proteles amplidentus is an extinct species of hyena closely related to the aardwolf. It lived during the Plio-Pleistocene in South Africa, where fossils have been found in the Swartkrans dated to as recently as 1.5 million years ago.
Kerberos ("Cerberus") is an extinct genus of hyainailourid hyaenodonts in the subfamily Hyainailourinae, that lived in Europe. It contains the single species Kerberos langebadreae.
