This is a list of South American animals 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] The list includes animal extinctions in the Galápagos, Falklands, and other islands near the continent.
The Paleocene Epoch lasted from 66 million to 56 million years ago. Modern placental mammals originated during this time. [10] The devastation of the K–Pg extinction event included the extinction of large herbivores, which permitted the spread of dense but usually species-poor forests. [11] [12] The Early Paleocene saw the recovery of Earth ...
This is a list of North American animals 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] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
Plesiadapis is one of the oldest known primate-like mammal genera which existed about 58–55 million years ago in North America and Europe. [2] [3] Plesiadapis means "near-Adapis", which is a reference to the adapiform primate of the Eocene period, Adapis.
It has been proposed that 20 tonnes (44,000 lb) may be the maximum weight possible for land mammals, and Paraceratherium was close to this limit. [46] The reasons mammals cannot reach the much larger size of sauropod dinosaurs are unknown. The reason may be ecological instead of biomechanical, and perhaps related to reproduction strategies. [34]
At least 37 genera of mammals were eliminated, including most of the megafauna. [5] While South America currently has no megaherbivore species weighing more than 1000 kg, prior to this event it had a menagerie of about 25 of them (consisting of gomphotheres , camelids , ground sloths , glyptodonts , and toxodontids – 75% of these being "old ...
Some scientists say the “Lunar Anthropocene” epoch started in 1959 when the first spacecraft sent by humanity landed on the moon. And it’s just the beginning.
During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
