High Arctic camel : ウィキペディア英語版
High Arctic camel

The High Arctic camel, from the mid-Pliocene epoch, is a fossil camel related to the fossil genus ''Paracamelus'' from which modern camels arose. It is also related to the extinct Ice Age Yukon giant camel. Collagen-containing fossils were found in 2006 near Strathcona Fiord on Ellesmere Island in Nunavut, Canada. The High Arctic camel lived at least 3.4 million years ago during a warmer period in a boreal-type forest environment.
==Fossil discovery==
The remains of the High Arctic camel were discovered over several field seasons (2006-2010) in the Strathcona Fiord area of Ellesmere Island, in the Canadian Arctic Archipelago, at about 78°N latitude. About 30 fragments were collected from the Fyles Leaf Bed site and assembled, forming part of a right tibia. The presence of a fibular notch at the distal end of the bone suggests the bone was from an artiodactyl hooved mammal (e.g. cows, deer, camels). Size estimates are consistent with camels, as they were the largest artiodactyls in North America at the time. This is the first evidence of camels in the High Arctic and a new taxon for the mammal assemblage of the Pliocene High Arctic.
