| Résumé | (disponible en anglais seulement)
This report concerns macro-remains of arthropods from Neogene sites in Alaska and northern Canada. New data from known or recently investigated localities are
presented and comparisons made with faunas from equivalent latitudes in Asia and Greenland. Many of the Canadian sites belong to the Beaufort Formation, a prime source of late Tertiary plant and insect fossils. But new sites are continually being
discovered and studied and among the most informative of these are several from the high terrace gravel on Ellesmere Island. One Ellesmere Island locality, known informally as the 'Beaver Peat' contains spectacularly well preserved plant and
arthropod fossils, and is the only Pliocene site in Arctic North America to yield a variety of vertebrate fossils. Like some of the other 'keystone' localities discussed here, it promises to be important for dating and correlation as well as for
documenting high Arctic climatic and environmental conditions during the Pliocene.
Arthropod fossils are becoming increasingly valuable for dating and correlation of Arctic Neogene sites. Such assemblages of fossils will ultimately prove valuable
for dating and interpretation of deep scientific boreholes drilled in the Arctic. Furthermore, the Tertiary fossils discussed aid in dating Quaternary deposits in the North American Arctic, because they show how Tertiary faunas differ from those of
Quaternary age. The faunas mentioned in this paper also aid in definition of former biotic gradients enhance our understanding of the history of the boreal and tundra biome. The earliest evidence for tundra is in the Pliocene at 80° N, not in the
late Miocene as some have suggested. The boreal realm of the Pliocene was qualitatively different from that of the present and much more extensive latitudinally. |
