Paleoecological Significance of Mummified Remains of Pleistocene Horses from the North Slope of the Brooks Range, Alaska

  title={Paleoecological Significance of Mummified Remains of Pleistocene Horses from the North Slope of the Brooks Range, Alaska},
  author={Russell D. Guthrie and Sam W. Stoker},
Radiocarbon dates from horse fossils found on the North Slope of Alaska show that horses did live there during the last peak glacial (Duvanny Yar Interval, Marine Isotope Stage 2). Some previous paleoecological studies have assumed the region's climate was too extreme for large mammals during the Duvanny Yar. Hoof structure suggests the Pleistocene horses survived on winter range characterized by low snowfall and/or snow removal by wind. Hoof growth rate suggests a substantial dietary volume of…

Late Pleistocene Vertebrates and Other Fossils from Epiguruk, Northwestern Alaska

Abstract Sediments exposed at Epiguruk, a large cutbank on the Kobuk River about 170 km inland from Kotzebue Sound, record multiple episodes of glacial-age alluviation followed by interstadial

New Radiocarbon-Dated Vertebrate Fossils from Herschel Island: Implications for the Palaeoenvironments and Glacial Chronology of the Beaufort Sea Coastlands

Palaeontological research on Herschel Island, Yukon, has yielded a diverse collection of Quaternary marine and terrestrial vertebrate fossils. The terrestrial faunal remains, which have largely been

The horse in late Pleistocene and Holocene Britain

Until now, the horse was one of the few members of the British Late Pleistocene and Holocene fauna which had yet to be fully investigated. In this thesis, chronological, palaeoecological and

the eastern beringian chronology of quaternary extinctions: a methodological approach to radiocarbon evaluation

Debate continues on the global phenomenon of human dispersal and subsequent megafauna extinc tions. In Eastern Beringia, species chronologies are only generally established and do not provide enough

Life and extinction of megafauna in the ice-age Arctic

It follows that long-distance dispersal was crucial for the long-term persistence of megafaunal species living in the Arctic and implies that regional extinctions followed by population reestablishment from distant refugia were characteristic features of ice-age biogeography at high latitudes.

Mid-Wisconsinan eolian deposits of the Kittigazuit Formation, Tuktoyaktuk Coastlands, Northwest Territories, Canada

The Kittigazuit Formation is a late Quaternary sand unit commonly observed throughout the Tuktoyaktuk Coastlands and in subbottom sediments of the southern Beaufort Shelf. Stratigraphic and

Proboscideans from US National Park Service Lands

Proboscideans (Mammalia, Proboscidea) are an ubiquitous part of North American vertebrate faunas throughout the Miocene, Pliocene, and Pleistocene. Here we discuss the fossil record of proboscideans

Ecology of a steppe‐tundra gradient in interior Alaska

. Subarctic steppe is currently restricted in interior Alaska and the Yukon Territory to steep, south-facing river bluffs. Paleoecological and biogeographic evidence suggests that some steppe taxa



Paleoecology of the Large-mammal Community in Interior Alaska during the Late Pleistocene

The high percentage of grazers in the fossil community suggests that interior Alaska was a grassland en- vironment during the late Pleistocene, leaving the comparatively depauperate community that exists in Alaska today.

Pollen stratigraphy from Hanging Lake in unglaciated northern Yukon provides evidence for a late Pleistocene to early Holocene warm interval initially recognized by McCulloch and Hopkins (1966).

A pleistocene sand sea on the alaskan arctic coastal plain.

This is the most extensive area of large stabilized dunes yet reported in the North American Arctic; the landscape is of particular interest because it has been proposed as a first-order analog for martian fretted terrain.

Pleistocene Mammals from Gold Run Creek, Yukon Territory

Remains of thirteen species of mammals are reported from Pleistocene deposits at Gold Run Creek near Dawson, Yukon Territory. Eight of the thirteen species are extinct and two are no longer living in

Frozen Fauna of the Mammoth Steppe: The Story of Blue Babe

Frozen mammals of the Ice Age, preserved for millennia in the tundra, have been a source of fascination and mystery since their first discovery over two centuries ago. These mummies, their ecology,

Equus lambei Hay, the Yukon Wild Horse, Not Ass

The proportions and morphology show that E. lambei is a horse, not an ass or a hemione, thus supporting Savage's (1951) conclusion as to its affinities, rather than that of Quinn (1957) or Harington and Clulow (1973).

The perissodactyls were the dominant medium to largesized herbivores during the Eocene, and in the early Oligocene a reduction in their diversity coincided with the beginning radiations of the ruminant groups of artiodactylS.
