Larus is a large genus of gulls with worldwide distribution.
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, sheep and goats. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene.
The family Natalidae, or funnel-eared bats, are found from Mexico to Brazil and the Caribbean islands. The family has three genera, Chilonatalus, Natalus and Nyctiellus. They are slender bats with unusually long tails and, as their name suggests, funnel-shaped ears. They are small, at only 3.5 to 5.5 cm in length, with brown, grey, or reddish fur. Like many other bats, they are insectivorous, and roost in caves.
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates.
The Mexican funnel-eared bat is a bat species. Despite its name, it is native to the Lesser Antilles in the Caribbean.
The tube-lipped nectar bat is a bat from Ecuador. It was described in 2005. It has a remarkably long tongue, which it uses to drink nectar. It additionally consumes pollen and insects.
Barbourofelidae is an extinct family of carnivorans of the suborder Feliformia, sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch and existed for about 7.9 million years. Thought to be an independent lineage from the Nimravidae and Machairodontinae, which had all attained elongated canines, recent research argues that it may be a subfamily of the Nimravidae, extending its biochronological range into the Miocene, although this issue is not yet fully resolved.
Myotis vivesi, the fish-eating bat or fish-eating myotis, is a species of bat that lives around the Gulf of California, and feeds on fish and crustaceans. It is the largest species of the genus Myotis in the Americas, and has exceptionally large feet, which it uses in hunting. It was described in 1901 by Auguste Ménégaux. It was previously considered the only member of the Myotis subgenus Pizonyx, but Pizonyx is now considered to contain all American Myotis species, along with two Eurasian ones.
Thylamys is a genus of opossums in the family Didelphidae. The premaxillae are rounded rather than pointed. The females lack a pouch. The females' nipples are arranged in two symmetrical rows on the abdomen. All species but T. macrurus store fat in their tails., although this is not necessarily true for all species in the genus. Fossils belonging to the genus date back to the Miocene, with the oldest specimens being found in the Cerro Azul Formation of Argentina and the Honda Group of Colombia. Genetic studies indicate that the genus may have originated around 14 million years ago.
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family. Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera.
The Saint Bathans mammal is a currently unnamed extinct primitive mammal from the Early Miocene of New Zealand. A member of the Saint Bathans fauna, it is notable for being a late-surviving "archaic" mammal species, neither a placental nor a marsupial. It also provides evidence that flightless fully terrestrial mammals did in fact once live in Zealandia. This is in contrast to modern New Zealand, where bats, cetaceans and seals are the only non-introduced mammals in the otherwise bird-dominated faunas.
Hesperotestudo is an extinct genus of tortoise native to North and Central America from the Early Miocene to the Late Pleistocene. Species of Hesperotestudo varied widely in size, with a large undescribed specimen from the Late Pleistocene of El Salvador reaching
Metaxytherium is an extinct genus of dugong that lived from the Oligocene until the end of the Pliocene. Fossil remains have been found in Africa, Europe, North America and South America. Generally marine seagrass specialists, they inhabited the warm and shallow waters of the Paratethys, Mediterranean, Caribbean Sea and Pacific coastline. American species of Metaxytherium are considered to be ancestral to the North Pacific family Hydrodamalinae, which includes the giant Steller's sea cow.
Archaeohippus is an extinct three toed member of the family Equidae known from fossils of early Oligocene to middle Miocene age. The genus is noted for several distinct skeletal features. The skull possesses deeply pocketed fossa in a notably long preorbital region. The genus is considered an example of phyletic dwarfism with adults estimated at being on average 20 kilograms in weight. This is in contrast to the most common equid of the period, Miohippus. Characters of the teeth show a mix of both primitive and advanced traits. The advanced traits are very similar to those shown in the genus Parahippus. The noted similarities of Archaeohippus and Parahippus show them to be descended from a common ancestor. They are considered sister species.
Antrozoini is a tribe of bats in the subfamily Vespertilioninae of the family Vespertilionidae. It contains the pallid bat, Van Gelder's bat, the genus Rhogeessa, and the fossil Anzanycteris. All species in this tribe are found in the Americas.
The Cuban greater funnel-eared bat is a species of funnel-eared bat. It is endemic to a cave in westernmost Cuba.
The St Bathans fauna is found in the lower Bannockburn Formation of the Manuherikia Group of Central Otago, in the South Island of New Zealand. It comprises a suite of fossilised prehistoric animals from the late Early Miocene (Altonian) period, with an age range of 19–16 million years ago.
The Alachua Formation is a Miocene geologic formation in Florida. The claystones, sandstones and phosphorites of the formation preserve many fossils of mammals, birds, reptiles and fish, among others megalodon.
The Mexican greater funnel-eared bat is a species of bat found in Central America. While initially and currently described as a species, from 1959 to 2006 it was considered a subspecies of the Mexican funnel-eared bat, Natalus stramineus.
Submyotodon is a genus of vespertilionid bats, published as a new taxon in 2003 to describe a Miocene fossil species. Extant species and subspecies previously included in Myotis were later transferred to this genus. Species in this genus are referred to as broad-muzzled bats or broad-muzzled myotises.
