Abies milleri, an extinct species of fir known from fossil remains found in deposits from the early Eocene Ypresian stage (around 49.5 mya) in Washington State, USA, is the oldest confirmed record for the fir genus. The species was described from 81 fossil specimens collected from Burke Museum site number A0307 in Ferry County, Washington. The holotype specimen, number # UWBM 31299, and the eleven paratype specimens are currently deposited in the collections of the Burke Museum in Seattle, where they were studied and described by Howard E. Schorn and Wesley C. Wehr. Schorn and Wehr published their 1986 type description for A. milleri in the Burke Museum Contributions in Anthropology and Natural History, Volume 1. The specific epithet, milleri, was coined in honor of Charles N. Miller Jr fo
