The Beaufort Formation records extraordinary details of Arctic environments and ampli ed temperatures at approximately
modern levels of atmospheric CO . It was deposited during the Neogene on the western side of what is now the Canadian
2
Arctic Archipelago. Meighen Island is a key locality for studying this forma tion because marine sediments there are
interbedded with ter
interbedded with terrestrial fossiliferous sands. The biostratigraphic succession, fossils from the marine restrial fossiliferous sands. The biostratigraphic succession, fossils from the marine
beds, and paleo magnetic data from the Bjaere Bay region of the island suggest two potential ages
for the studied exposures: either continuous deposition at ca. 3.0 Ma, or a sequence of deposits
at ca. 4.5 Ma and 3.4 Ma. The sediments appear to encompass at least two eustatic high-
stands of sea level and a particularly warm climate interval of the Pliocene Arctic.
