Tennessee, Cumberland, Ohio, and Wabash River systems [190] Extinct in 1936 due to loss of habitat through impoundment or channelization. [8] Sampson's pearly mussel. Epioblasma sampsonii. Kentucky, Illinois, and Indiana [191] Extinct in the 1930s or 1940s due to habitat destruction and fragmentation.
Extinctions in northern Eurasia were staggered over tens of thousands of years between 50,000 and 10,000 years ago, [2] while extinctions in the Americas were virtually simultaneous, spanning only 3000 years at most. [4][8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in ...
The Cretaceous–Paleogene (K–Pg) extinction event, [ a ] also known as the Cretaceous–Tertiary(K–T)extinction, [ b ] was the mass extinction of three-quarters of the plant and animal species on Earth [ 2 ][ 3 ] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.

Conservation status. The conservation status of a group of organisms (for instance, a species) 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 ...
Sauropod hiatus. The sauropod hiatus is a period in the North American fossil record for most of the Late Cretaceous noted for its lack of sauropod remains. It may represent an extinction event, possibly caused by competition with ornithischian herbivores, habitat loss from the expansion of the Western Interior Seaway, or both.
Passenger pigeon. The passenger pigeon or wild pigeon (Ectopistes migratorius) is an extinct species of pigeon that was endemic to North America. Its common name is derived from the French word passager, meaning "passing by", due to the migratory habits of the species. The scientific name also refers to its migratory characteristics.
Mammonteus primigenius Osborn, 1924. Elephas boreus Hay, 1924. The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived from the Middle Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with the African Mammuthus subplanifrons in the early Pliocene.
