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 ...
Lake Dana stage of Lake Lundy @ 590 feet (180 m) above sea level [7] Lake Grasmere stage of Lake Lundy @ 640 feet (200 m) above sea level [7] Lake Tonawanda; 10,000 YBP [8] in western New York; Lake Wayne; ended by 12,000 YBP [7] in Ohio, Pennsylvania, and New York, expanding from Lake Warren to cover most of the Erie basin [1]
Invertebrate fossils in Lake Bonneville deposits include mollusks and ostracodes, [1] [36] and bones of extinct mammals are found in Pleistocene deposits in the Bonneville basin. [37] Volcanic ashes in sediments of Lake Bonneville help with correlations and aid in deciphering lake history. [38]
Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene disruption: 14.5 Ma Climate change due to change of ocean circulation patterns. Milankovitch cycles may have also contributed [11] Paleogene: Eocene–Oligocene extinction event: 33.9 Ma
Lake Toba is the resulting crater lake The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption ) was a supervolcanic eruption that occurred around 74,000 years ago, during the Late Pleistocene , [ 2 ] at the site of present-day Lake Toba , in Sumatra , Indonesia .
The site also features rock surfaces in which the prehistoric man lived during the Pleistocene period. As a result of geologic breakage and foldage activity, the rock surfaces are now inclined at an angle of 70 degrees. It is thought that the area used to feature a pristine lake along which Homo erectus lived after his exodus from Africa. The ...
Lake Agassiz (/ ˈ æ ɡ ə s i / AG-ə-see) was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period. At its peak, the lake's area was larger than all of the modern Great Lakes combined. [2]
Lake Lahontan was a large endorheic prehistoric lake during the Pleistocene that occupied modern northwestern Nevada and extended into northeastern California and southern Oregon. The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west.
