Although a residual extant megafauna did survive the Pleistocene extinction event (e.g., red kangaroo, bison, Asian elephant, llama, etc.), the only continent on Earth where a diverse assemblage of megafauna remains is Africa, which is also where mod- ern humans arose.

Megafauna strongly influence vegetation structure, and population declines can alter ecosystem functioning. Overhunting of grazing megafauna is argued to have driven the collapse of widespread, northern steppe-tundra and its replacement by woody vegetation at the end of the ice age.
The Pleistocene Megafauna
The Late Pleistocene to the beginning of the Holocene saw numerous extinctions of predominantly megafaunal (large) animal species (the Pleistocene megafauna ), which resulted in a collapse in faunal density and diversity across the globe. [1]
La noche de los gigantes (y VI). La Megafauna africana y la extinción
The cause of the extinction of giant birds, reptiles, and mammals in the late Pleistocene is, for palaeobiology, what Fermat's last theorem was for mathematics ( ): a long-standing scientific puzzle that has captured the imagination of specialists and nonspecialists alike ( ).

To most, the term "Megafauna" conjures up images of large African mammals, such as elephants, giraffes, rhinoceroses, and lions. By comparison, today the largest land mammals in South America are wild camelids, tapirs, jaguars, and capybaras (Wilson and Reeder 2005).Yet, as recently as 10,000 years ago the landscape of South America contained remarkable beasts—massive mammals that.
Fauna of the Pleistocene by Mauricio Antón Prehistoric Wildlife
Pleistocene Era Extinctions . Before early modern humans left Africa to colonize the rest of the world, all of the continents were already populated by a large and diverse animal population, including our hominid cousins, Neanderthals, Denisovans, and Homo erectus.Animals with body weights greater than 100 pounds (45 kilograms), called megafauna, were abundant.
The Pleistocene was a time of giants. Before their mysterious vanishing
The worldwide extinction of megafauna during the Late Pleistocene and Early Holocene is evident from the fossil record, with dominant theories suggesting a climate, human or combined impact.
Pleistocene Epoch megafauna from the region of Chapada Diamantina
Toward the end of the Pleistocene, North America lost 37 mammalian genera including over 70% of its megafauna, commonly defined as terrestrial taxa exceeding 44 kg 1.Although part of a broader.

Abstract. Giant vertebrates dominated many Pleistocene ecosystems. Many were herbivores, and their sudden extinction in prehistory could have had large ecological impacts. We used a high-resolution 130,000-year environmental record to help resolve the cause and reconstruct the ecological consequences of extinction of Australia's megafauna.

Megafaunal extinctions The end of the Pleistocene was marked by the extinction of many genera of large mammals, including mammoths, mastodons, ground sloths, and giant beavers. The extinction event is most distinct in North America, where 32 genera of large mammals vanished during an interval of about 2,000 years, centred on 11,000 bp.
Herbivorous megafauna in Pleistocene North America r/quatria
The disappearance of many North American megafauna at the end of the Pleistocene is a contentious topic. While the proposed causes for megafaunal extinction are varied, most researchers fall into.

Pleistocene Megafauna in Beringia By Pamela Groves, University of Alaska An artist's interpretation of ice age fauna. Image courtesy of Mauricio Antón At the peak of the last ice age, 20,000 years ago, when most of northern North America was covered by massive glaciers, much of Alaska was ice-free and home to a diverse assortment of large mammals.

The drivers of megafauna extinctions have drastically shifted between the Pleistocene (between 2.6 million and 11,700 years before present), Holocene [11,700 to 100 years before present (8, 9)], and Anthropocene epochs [<70 years before present ()].During the Pleistocene, slowly operating geological, climatic, and biological processes, such as fluctuations in sea levels and the resulting.
