The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals (with small animals being largely unaffected), and widespread absence of ecological succession to replace these extinct megafaunal species, [3] and the regime shift of previously established faunal ...
The shaded relief map of the Gulf of Mexico and Caribbean Sea area contoured at -100 m depth. [7] [8]In Florida, the pristine mustached bat became locally extinct at the end of the Pleistocene, [3] [5] what probably resulted from the rise in sea level, the subsequent flooding of caves and loss of roosting sites.
Eocene–Oligocene extinction event: 33.9 Ma: Multiple causes including global cooling, polar glaciation, falling sea levels, and the Popigai impactor [12] Cretaceous: Cretaceous–Paleogene extinction event: 66 Ma Chicxulub impactor; the volcanism which resulted in the formation of the Deccan Traps may have contributed. [13] Cenomanian ...
Chendytes lawi is an extinct, goose-sized flightless marine duck, once common on the California coast, the California Channel Islands, and possibly southern Oregon. It lived in the Pleistocene and survived into the Holocene. It appears to have gone extinct at about 450–250 BCE. [3]
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
Highly specialised for grazing, with the narrowest range of all Pleistocene ground quirrels. The latest possible date is the Atlantic, and its extinction was probably related to the local collapse of the mammoth steppe.

The large-toothed sea otter is a close relative of the living sea otter. As its name implies, it is distinguishable from the modern sea otter by its larger, more robust teeth. [3] Fossils of the large-toothed sea otter are dated to between 700 and 500 ka. [4]
