Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
The following list is incomplete by necessity, since the majority of extinctions are thought to be undocumented, and for many others there isn't a definitive, widely accepted last, or most recent record. According to the species-area theory, the present rate of extinction may be up to 140,000 species per year. [1]
Holocene extinctions, biological taxa that went extinct during the current geological/paleobiological Holocene epoch of the Quaternary Period. Extinct plant/flora and animal/fauna species of the last 12,000 years (occurring from ~10,000 BCE to the present day.
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.
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, [109] [110] is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
This is a list of European species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] This list includes the European continent and its surrounding islands.
In the group of molluscs known as the cephalopods, as of 1987 there were approximately 600 extant species and 7,500 extinct species. [1] A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries ...
Known from an undated femur from either the late Pleistocene or early Holocene. Its morphology suggests arboreality, making unlikely that it became extinct when forests expanded in the Holocene. It might have become extinct due to human-induced habitat loss instead. [15] Diminute Jamaican hutia [6] Xaymaca fulvopulvis: Jamaica
