Eleven cycloid fish scales or scale fragments with scalloped anterior margins were obtained from a Pleistocene deposit in the Old Crow area, Yukon Territory. Shells from the same horizon as the scales were radiocarbon dated at 32 400 ± 770 yr B.P. The scales are from the Arctic grayling, Thymallus arcticus, providing the first fossil records of the genus and of the subfamily Thymallinae for North America.
