Holocene dwarf mammoths from Wrangel Island in the Siberian Arctic

Article Abstract:

It is generally agreed that the wooly mammoth became extinct about 10,000-12,000 years ago. However, radiocarbon-dating of mammoth fossils gathered from Wrangel Island in the Siberian Arctic shows that a subpopulation of wooly mammoths survived up to 7,000-4,000 years ago. Analysis of teeth fossils showed that this subpopulation consisted of normal-sized mammoths and a dwarfed form. The dwarfed form may be the result of insular dwarfing, when Wrengel Island separated from the mainland about 12,000 years ago.

Mammoths in miniature

Article Abstract:

Previous radiocarbon-dating evidence has suggested that the wooly mammoth became extinct 12,000 to 10,000 years ago during the Late Pleistocene. However,recent findings from Wrangel Island in the Arctic Ocean indicates that a subpopulation of wooly mammoths survived up to 7,000 to 4,000 years ago. This population of wooly mammoths were composed of typical-sized mammoths as well asdwarfed ones.

Radiocarbon evidence of mid-Holocene mammoths stranded on an Alaskan Bering Sea island

Article Abstract:

Four lines of evidence such as 265 accelerator mass spectrometer radiocarbons dates from Alaskan mainland mammoths, 13 new dates from Alaskan island mammoths, recent reconstructions of bathymetric plots and sea transgression rates from the Bering sea made it possible to reconstruct the way in which mammoths became stranded in the Pribilofs.
