Digerus gibberulus is an extinct species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Odontostomidae. cf. [2]
This species was endemic to Brazil; it is considered now extinct. [1]
Extinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
The family Dipluridae, known as curtain-web spiders are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (Atrax), used to be classified in this family but have now been moved to Atracidae.
The harpy eagle is a neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea harpy eagle or Papuan harpy eagle. It is the largest and most powerful bird of prey found throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. In Brazil, the harpy eagle is also known as royal-hawk. The genus Harpia, together with Harpyopsis and Morphnus, form the subfamily Harpiinae.
The Atlantic Forest is a South American forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where the region is known as Selva Misionera.
Local extinction, also extirpation, is the termination of a species in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions.
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may generally refer to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
The Tietê River is a Brazilian river in the state of São Paulo.
The Paraíba do Sul, or simply termed Paraíba, is a river in southeast Brazil. It flows 1,137 km (706 mi) west to northeast from its farthest source at the source of the river Paraitinga to the sea near Campos dos Goytacazes. The river receives its name when it meets the river Paraibuna at the Paraibuna dam.
Aratinga is a genus of South American conures. Most are predominantly green, although a few are predominantly yellow or orange. They are social and commonly seen in groups in the wild. In Brazil, the popular name of several species usually is jandaia, sometimes written as jandaya in the scientific form.
Tomigerus is a genus of air-breathing, tropical land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae.
Biotocus turbinatus was a species of land snail, a gastropod in the family Odontostomidae.
The oceanic eclectus is an extinct parrot species which occurred on Tonga, Vanuatu and possibly on Fiji. Its only living relative is the eclectus parrot, which has proportionally larger wings than the oceanic eclectus parrot. The fossil material unearthed in November 1989 in Late Pleistocene and Holocene deposits on 'Eua, Lifuka, 'Uiha and Vanuatu and described in 2006 by David William Steadman include a complete femur, five radii, a quadrate bone, a mandible, a coracoid, two sterna, two humeri, two ulnae, two tibiotarsi, a carpometacarpus, a tarsometatarsus, and three pedal phalanges.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Caririemys is an extinct genus of side-necked turtles, belonging to the Pelomedusoides of the family Euraxemydidae. The type species is C. violetae. A single fossil of an individual was found in the Santana Formation in Brazil, an 80-million-year-old Late Cretaceous deposit that has so far preserved other fossil reptiles such as dinosaurs and crocodilians.
Amphibromus is a genus of grasses in the family Poaceae. Most are known as swamp wallaby grass. Most are endemic to Australia. One can also be found in New Zealand and there are two species in South America.
Irajatherium is an extinct genus of cynodonts, known only of the type species Irajatherium hernandezi. It is named in honor of Irajá Damiani Pinto.
Gibberulus gibberulus, common name the humpbacked conch, is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Gibberulus is a genus of sea snails, marine gastropod mollusks in the family Strombidae, the true conchs.
Cryopterygius is an extinct genus of ophthalmosaurid ichthyosaur known from the uppermost Jurassic of Central Spitsbergen, Norway. The type species, Cryopterygius kristiansenae , is known from a single, but largely complete specimen from the Slottsmøya Member of the Agardhfjellet Formation. With a total length of 5–5.5 metres (16–18 ft), it is a large ichthyosaur. A second species, C. kielanae, was found in the Kcynia Formation from the Late Jurassic of Poland. It is smaller than the type species, with a length of 3.5–4 metres (11–13 ft).
