Description
Summary:Ten Pleistocene fossils representing loons of the species Gavia stellata, Gavia arctica, Gavia immer, and Gavia cf. adamsii are reported from the Old Crow Basin in the northern Yukon Territory, an area which is presently outside the range of G. adamsii. One specimen of G. arctica is from beds that correlate to beds dating > 54 000 years BP and are presumed to be of Sangamon interglacial age. Two specimens of G. stellata and one of G. cf. adamsii have minimum dates of about 10 700 years BP.
