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.
