| ancient dna reveals late survival of mammoth and horse in interior alaska. | causes of late quaternary extinctions of large mammals ("megafauna") continue to be debated, especially for continental losses, because spatial and temporal patterns of extinction are poorly known. accurate latest appearance dates (lads) for such taxa are critical for interpreting the process of extinction. the extinction of woolly mammoth and horse in northwestern north america is currently placed at 15,000-13,000 calendar years before present (yr bp), based on lads from dating surveys of macro ... | 2009 | 20018740 |
| was frozen mammoth or giant ground sloth served for dinner at the explorers club? | accounts of woolly mammoths (mammuthus primigenius) preserved so well in ice that their meat is still edible have a long history of intriguing the public and influencing paleontological thought on quaternary extinctions and climate, with some scientists resorting to catastrophism to explain the instantaneous freezing necessary to preserve edible meat. famously, members of the explorers club purportedly dined on frozen mammoth from alaska, usa, in 1951. this event, well received by the press and ... | 2016 | 26840445 |
| timing and causes of mid-holocene mammoth extinction on st. paul island, alaska. | relict woolly mammoth (mammuthus primigenius) populations survived on several small beringian islands for thousands of years after mainland populations went extinct. here we present multiproxy paleoenvironmental records to investigate the timing, causes, and consequences of mammoth disappearance from st. paul island, alaska. five independent indicators of extinction show that mammoths survived on st. paul until 5,600 ± 100 y ago. vegetation composition remained stable during the extinction windo ... | 2016 | 27482085 |
