The extinction of the megafauna has been argued by some authors to be disappearance of the mammoth steppe rather than the other way around. Alaska now has low nutrient soil unable to support bison, mammoths, and horses. R. Dale Guthrie has claimed this as a cause of the extinction of the megafauna there; however, he may be interpreting it ...
Megafauna animals – in the sense of the largest mammals and birds – are generally K-strategists, with high longevity, slow population growth rates, low mortality rates, and (at least for the largest) few or no natural predators capable of killing adults.
North Central Europe and the British Isles to Crimea and the Middle Urals: Most recent remains in north Central Europe are dated to 8750 BCE. [2] However, remains have been dated to the late Holocene in Ukraine, and one account describes a large, unidentified, "red-cheeked" ground squirrel in the early 20th century of the Dnipropetrovsk area.

Turiasaurus is considered the largest dinosaur from Europe, [435] [436] with an estimated length of 30 m (98 ft) and a weight of 50 t (55 short tons). [ 430 ] [ 436 ] However, lower estimates at 21 m (69 ft) and 30 t (66,000 lb) would make it smaller than the Portuguese Lusotitan , which reached 24 m (79 ft) in length and 34 t (75,000 lb) in ...
Megafauna that arose on insular landmasses were especially vulnerable to human influence because they evolved in isolation from other landmasses, and thus were not subjected to the same selection pressures that surviving fauna were subject to, and many forms of insular megafauna were wiped out after the arrival of humans.
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
Parts of the video highlight plumes of smoke rising into the air, as the hot lava makes contact with snow and vegetation. Volcanic activity of Mt. Etna was also linked to earthquakes in the vicinity.
These "dogs" had a wide size range, from over 60 cm (2 ft) in height in eastern Europe to less than 30–45 cm (1 ft–1 ft 6 in) in central and western Europe, [103] and 32–41 kg (71–90 lb) in all of Europe. These "dogs" are identified by having a shorter snout and skull, and wider palate and braincase than contemporary wolves.
