Bluebuck The bluebuck (Afrikaans: bloubok ) or blue antelope ("Hippotragus leucophaeus") is an extinct species of antelope that lived in South Africa until around 1800. It is congeneric with the roan antelope and sable antelope (belonging in the genus "Hippotragus"), but was smaller than either. It was sometimes considered a subspecies of the roan antelope, but a genetic study has confirmed it as a distinct species.

Metriorhynchus Metriorhynchus is an extinct genus of marine crocodyliform that lived in the oceans during the Middle to Late Jurassic. "Metriorhynchus" was named by the German palaeontologist Christian von Meyer in 1830. "Metriorhynchus" was a carnivore that spent much, if not all, its life out at sea. No "Metriorhynchus" eggs or nests have been discovered, so little is known of the reptile's life cycle, unlike other large marine reptiles of the Mesozoic, such as plesiosaurs or ichthyosaurs which are known to give birth to live young out at sea. Where "Metriorhynchus" mated, whether on land or at sea, is currently unknown. The name "Metriorhynchus" means "Moderate snout", and is derived from the Greek "Metrio"- ("moderate") and -"rhynchos" ("snout").

Lazarussuchus Lazarussuchus (meaning "Lazarus's crocodile") is a genus of basal choristodere, a type of amphibious reptile, known from France, Germany, and the Czech Republic. Fossils have been found in Late Paleocene, Late Oligocene, and Early Miocene deposit, meaning that the genus lasted about 40 million years. Two species have been named: the type species "L. inexpectatus" ("unexpected") (Hecht, 1992) from the late Oligocene of France and Germany and "L. dvoraki" (for Zdeněk Dvořák) from the early Miocene of the Czech Republic. It was not a large animal; the skull of "L. inexpectatus" was only about 4.53 centimeters long (1.78 in). A complete specimen of "Lazarussuchus" with preserved soft tissue was found from the Late Paleocene of France, but has not been assigned to a species.

Rhodonaspis Rhodonaspis is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived from 501 to 490 million years ago during the Dresbachian faunal stage of the late Cambrian Period.

Arandaspis Arandaspis prionotolepis is an extinct species of jawless fish that lived in the Ordovician period, about 480 to 470 million years ago. Its remains were found in Alice Springs, Australia in 1959, but it was not determined that they were the oldest known vertebrates until the late 1960s. "Arandaspis" is named after a local Aboriginal tribe, the Aranda (now currently called Arrernte).

Saniwa Saniwa is an extinct genus of monitor lizards that lived during the Eocene epoch around 48 million years ago. Well-preserved fossils have been found in the Bridger and Green River Formations of Wyoming, and evidence indicates "Saniwa" also lived in Europe. The type species "S. ensidens" was named in 1870 as the first fossil lizard known from North America. Several other species have since been added, but their validity is uncertain. It is a close relative of "Varanus", the genus that includes extant monitor lizards.

Rhizodontida Rhizodonts (order Rhizodontida) are an extinct group of predatory tetrapodomorph fishes known from many areas of the world from the Givetian through to the Pennsylvanian - the earliest known species is about 377 million years ago (Mya), the latest around 310 Mya. Rhizodonts lived in tropical rivers and freshwater lakes and were the dominant predators of their age. They reached huge sizes - the largest known species, "Rhizodus hibberti" from Europe and North America, was an estimated 7 m in length, making it the largest freshwater fish known.

Pengana Pengana robertbolesi, also referred to as the flexiraptor, is an extinct bird of prey that lived during the Early Miocene (23–16 million years ago). Living relatives of "P. robertbolesi" may include the harriers. When alive, it may have resembled a cross between the secretary bird and crested caracara.

Arsinoitherium Arsinoitherium is an extinct genus of paenungulate mammal belonging to the extinct order Embrithopoda. It is related to elephants, sirenians, hyraxes and the extinct desmostylians. Arsinoitheres were superficially rhinoceros-like herbivores that lived during the late Eocene and the early Oligocene of northern Africa from 36 to 30 million years ago, in areas of tropical rainforest and at the margin of mangrove swamps. A species described in 2004, "A. giganteum", lived in Ethiopia about 27 million years ago.

Phascogale The phascogales (members of the eponymous genus "Phascogale"), also known as wambengers, are carnivorous Australian marsupials of the family Dasyuridae. There are three species: the brush-tailed phascogale ("Phascogale tapoatafa"), the red-tailed phascogale ("Phascogale calura"), and the northern brush-tailed phascogale ("Phascogale pirata"). As with a number of dasyurid species, the males live for only one year, dying after a period of frenzied mating. The term "Phascogale" was coined in 1824 by Coenraad Jacob Temminck in reference to the brush-tailed phascogale, and means "pouched weasel". All three species are listed as either Near Threatened or Vulnerable by the IUCN.
