The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone.
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia.
Microbiotheria is an australidelphian marsupial order that encompasses two families, Microbiotheriidae and Woodburnodontidae, and is represented by only one extant species, the monito del monte, and a number of extinct species known from fossils in South America, Western Antarctica, and northeastern Australia.
Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and Australasia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. In the past, they were included in the family Fagaceae, but genetic tests revealed them to be genetically distinct, and they are now included in their own family, the Nothofagaceae.
The Antarctic flora is a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. It is now found on several separate areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia and New Caledonia. Joseph Dalton Hooker was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.
Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera, almost entirely native to the Americas, from Central America to southern South America. One species of Luzuriaga occurs in New Zealand, and the genus Drymophila is endemic to south-eastern Australia.
The Monimiaceae is a family of flowering plants in the magnoliid order Laurales. It is closely related to the families Hernandiaceae and Lauraceae. It consists of shrubs, small trees, and a few lianas of the tropics and subtropics, mostly in the southern hemisphere. The largest center of diversity is New Guinea, with about 75 species. Lesser centres of diversity are Madagascar, Australia, and the neotropics. Africa has one species, Xymalos monospora, as does Southern Chile. Several species are distributed through Malesia and the southwest Pacific.
Neuquenraptor is a genus of dromaeosaurid theropod dinosaurs that lived in South America during the Late Cretaceous in what is now the Portezuelo Formation of Argentina. It is one of the first dromaeosaurids found in the Southern Hemisphere.
Siparunaceae is a family of flowering plants in the magnoliid order Laurales. It consists of two genera of woody plants, with essential oils: Glossocalyx in West Africa and Siparuna in the neotropics. Glossocalyx is monospecific and Siparuna has about 74 known species.
Timimus is a genus of small coelurosaurian theropod dinosaur from the Early Cretaceous of Australia. It was originally identified as an ornithomimosaur, but now it is thought to be a different kind of theropod, possibly a tyrannosauroid.
Riojasuchus is an extinct genus of Late Triassic (Norian) quadrupedal crurotarsan archosaur. Riojasuchus is a member of Ornithosuchidae, a family of facultatively bipedal carnivores that were geographically widespread during the Late Triassic. Two other genera, Ornithosuchus and Venaticosuchus, are currently known. The holotype specimen is PVL 3827. It was found in the Los Colorados Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina.
Santanaraptor is a genus of tyrannosauroid dinosaur that lived in South America during the Early Cretaceous, about 112 million years ago.
Bomarea is one of the two major genera in the plant family Alstroemeriaceae. Most occur in the Andes, but some occur well into Central America, Mexico and the West Indies. Some species are grown as ornamental plants.
In taxonomy, an undescribed taxon is a taxon that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a nomen nudum. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published.
Gondwana or Gondwanaland was a supercontinent that existed from the Neoproterozoic and began to break up during the Jurassic, with the opening of the Drake Passage, separating South America and Antarctica occurring during the Eocene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it.
Doryphora is a genus of plant in the family Atherospermataceae, or formerly Monimiaceae. It contains four species, two endemic to Australia.
Hedycarya is a genus of dioecious trees and shrubs of the family Monimiaceae. Species occur in South East Asia, New Caledonia, Australia and Polynesia including New Zealand. The genus was named and formerly described in 1776 by botanists Johann and Georg Forster in Characteres Generum Plantarum . The limit of the genus may require change as it appears paraphyletic in phylogenetic analyses, with the genera Kibaropsis and Levieria nested in it.
Titanogomphdon is an extinct genus of diademodontid cynodonts from the Middle Triassic Omingonde Formation of Namibia. It is known from a single partial skull that was described in 1973 from the Omingonde Formation. The type and only species is Titanogomphodon crassus. At about 40 centimetres (16 in), the skull of Titanogomphodon was significantly larger than that of its closest relative, Diademodon. Its teeth are similar to those of another group of cynodonts called Traversodontidae, but the similarities are likely the result of convergent evolution. Aside from its larger size, Titanogomphodon differs from Diademodon in having a bony projection on the postorbital bar behind the eye socket.
Mupashi is an extinct monotypic genus of therocephalians that lived during the Late Permian of what is now Zambia. It was relatively small-bodied and had a long snout with a high tooth count compared to most other therocephalians. The size of its sclerotic ring suggests that it was adapted to be active in low-light conditions.
Don Foreman was an Australian botanist who worked on the Monimiaceae and Proteaceae of Australia. He also helped with the editing of selected Flora of Victoria and Flora of Australia Volumes.
