Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms.
Stilt is a common name for several species of birds in the family Recurvirostridae, which also includes those known as avocets. They are found in brackish or saline wetlands in warm or hot climates.
The large bird genus Columba comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove, has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon.
Cladium is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence. Like many plants found in wet habitats, it has deeply buried rhizomes that can produce tall shoots with dense canopies.
The waterfowl genus Anser includes the grey geese and the white geese. It belongs to the true geese and swan subfamily (Anserinae). The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed further south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) to 5 °C (41 °F) isotherms.
Phlaocyon is an extinct genus of the Borophaginae subfamily of canids native to North America. It lives from the Early Oligocene to the Early Miocene epoch 33.3–16.3 Mya, existing for approximately 17.3 million years. It is closely related to Cynarctoides.
Cormohipparion is an extinct genus of horse belonging to the tribe Hipparionini that lived in North America during the late Miocene to Pliocene. This ancient species of horse grew up to 3 feet long.
Hesperotestudo is an extinct genus of tortoise native to North and Central America from the Oligocene to the Late Pleistocene. Species of Hesperotesudo varied widely in size, with the largest unnamed species from El Salvador reaching 150 cm (4.9 ft) in carapace length, larger than that of extant giant tortoises. Historically considered a subgenus of Geochelone, it is now considered to be distantly related to that genus. Its closest relatives are the extant Gopherus and the extinct Stylemys. The ancestor of the three genera arrived in North America during the Early Eocene. The bodies of Hesperotesudo species were extensively covered with large dermal ossicles, which in life were covered in keratin. It has been suggested that species of Hesperotestudo were relatively tolerant of cold weather. Hesperotestudo became extinct at the end of the Pleistocene and beginning of the Holocene co-incident with the arrival of the first humans in North America, and sites have been found where Hesperotestudo were butchered.
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.
Oligobunis is an extinct genus of mustelids, which existed during the Miocene epoch.
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 20kg 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 and are considered sister species.
The Thomas Farm site is an Early Miocene, Hemingfordian assemblage of vertebrate fossils located in Gilchrist County, northern Florida.
Ecphora is the common name for a group of extinct predatory marine gastropod mollusks within the family Muricidae, the rocks snails or murexes. The common name is based on the first officially described genus, Ecphora. The entire lineage of these ocenebrinid murexes are descended from the Eocene murex, Tritonopsis. Ecphoras are indigenous to the North American Eastern Seaboard, being found in marine strata from the Late Eocene until their extinction during the Pliocene. Many ecphora species are important index fossils.
Thecachampsa is an extinct genus of gavialoid crocodylian, traditionally regarded as a member of the subfamily Tomistominae. Fossils have been found from the eastern United States in deposits of Miocene age. Those named in the 19th century were distinguished primarily by the shape of their teeth, and have since been combined with T. antiquus. More recently erected species were reassigned from other genera, although their assignment to Thecachampsa has since been questioned.
Primophaps schoddei is an extinct genus and species of bird in the pigeon family. It was described from Late Oligocene material found at Riversleigh in north-western Queensland, Australia. It was closely related to the Australian bronzewing pigeons, especially those in the genus Phaps. The genus name comes from the Latin primordium,, and the Greek phaps (“pigeon”). The specific epithet honours Australian taxonomist Richard Schodde for his work on the relationships of Australian birds.
Rupephaps taketake, also referred to as the Saint Bathans pigeon, is an extinct species of pigeon from the Miocene of New Zealand. It is the first species of columbid to be described from pre-Pliocene fossil deposits in the Australasian region.
Manuherikia is a genus of extinct species of ducks from the Miocene of New Zealand. It was described from fossil material of the Saint Bathans Fauna, in the lower Bannockburn Formation of the Manuherikia Group, found by the Manuherikia River in the Central Otago region of the South Island. The genus name comes from the name of the geological formation in which the fossils were found and, ultimately, from the Manuherikia River and its valley.
Primonatalus prattae is a fossil bat species from the family of the Natalidae which lived in the early Miocene in Florida. This animal, the only species of the genus Primonatalus, is known from 32 fossils.
The Tongan tooth-billed pigeon, is an extinct species of pigeon that was endemic to Tonga that lived in the Quaternary period. A related species, the tooth-billed pigeon, is the only known living species in its genus.
