Cimolodon is a genus of the extinct mammal order of Multituberculata within the suborder Cimolodonta and the family Cimolodontidae. Specimens are known from the Late Cretaceous of North America.
Anconodon is an extinct genus of mammal from the Paleocene of North America, and thus lived just after the "age of the dinosaurs". It was a member of the extinct order Multituberculata within the suborder Cimolodonta and possibly the family Cimolodontidae.
Essonodon is a mammal genus from the Upper Cretaceous of North America. It was a member of the extinct order Multituberculata and lived towards the end of the "age of the dinosaurs." It is within the suborder Cimolodonta and perhaps the family Cimolomyidae.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Fossil Butte National Monument is a United States National Monument managed by the National Park Service, located 15 miles (24 km) west of Kemmerer, Wyoming, United States. It centers on an assemblage of Eocene Epoch animal and plant fossils associated with Fossil Lake—the smallest lake of the three great lakes which were then present in what are now Wyoming, Utah, and Colorado. The other two lakes were Lake Gosiute and Lake Uinta. Fossil Butte National Monument was established as a national monument on October 23, 1972.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish, or even living fossils, due to their current rarity and similarity to extinct forms. Fish which have become recently extinct are not usually referred to as prehistoric fish. They were very different from what we have today. They likely were larger and had tougher scales.
The gray-lined hawk is a smallish raptor found in open country and forest edges. It is sometimes placed in the genus Asturina as Asturina nitida. The species has been split by the American Ornithological Society from the gray hawk. The gray-lined hawk is found from El Salvador to Argentina, as well as on the Caribbean island of Trinidad.
Emmelichthys nitidus, the Cape bonnetmouth, bonnetmouth, redbait, pearl fish, picarel, red baitfish, red herring or Southern rover, is a species of marine ray-finned fish belonging to the family Emmelichthyidae, the rovers and bonnetmouths. This species is found in the Indian and Pacific oceans. This species is of minor importance to commercial fisheries.
Lichen nitidus is a chronic inflammatory disease of unknown cause characterized by 1–2 mm, discrete and uniform, shiny, flat-topped, pale flesh-colored or reddish-brown papules that may appear as hypopigmented against dark skin. Occasionally, minimal scaling is present or can be induced by rubbing the surface of the papules. The disease usually affects children and young adults and is painless and usually nonpruritic, although protracted itching may occur in some cases. It is sometimes referred to by dermatologists as "mini lichen planus".
Ctenopharynx nitidus is a species of fish in the family Cichlidae. It is endemic to Lake Malawi.
Aviculopecten is an extinct genus of bivalve mollusc that lived from the Early Devonian to the Late Triassic in Asia, Australia, Europe, North America, and South America.
Sphoeroides nitidus is a species in the family Tetraodontidae, the pufferfishes. It is native to the Southwest Pacific, where it is known from New Zealand.
Bonnetmouth may refer to:
Rhabdoblennius nitidus, the barred-chin blenny, is a species of combtooth blenny found in coral reefs in the western Pacific ocean. This species reaches a length of 8.3 centimetres (3.3 in) SL.
Peltopleuridae were an extinct family of prehistoric bony fish. It is classified with the order Peltopleuriformes.
Emmelichthys is a genus of marine ray-finned fishes belonging to the family Emmelichthyidae, the rovers and bonnetmouths. The species in this genus are found in the Atlantic, Indian and Pacific Oceans.
Spondylurus is a genus of lizards in the family Scincidae. The genus Spondylurus, vernacularly known as the Antillean four-lined skinks, is a neotropical skink taxon including many species.
The glittering pipefish is a species of marine coastal fish of the family Syngnathidae. It is found in the Western Pacific, from Viet Nam to Fiji and from the Ryukyu Islands to New Caledonia, where it inhabits corals, sand and reef flats to depths of 20 metres (66 ft).< It can grow to lengths of 7.3 centimetres (2.9 in), and is expected to feed on small crustaceans, similar to other pipefishes. It is secretive and rarely observed. This species is ovoviviparous, with males carrying eggs and giving birth to live young.
