Title: Middle Bajocian ammonites from the Cook Inlet region, Alaska ,  1964
ABSTRACT

Jurassic ammonites of middle Bajocian age occur in the Tuxedni Group along the northwest side of Cook Inlet and in the Tuxedni Formation in the eastern part of the Talkeetna Mountain, Alaska. Numerically the dominant families are the Otoitidae and Stephanoceratidae. The families Phylloceratidae, Sonninidae, Oppelidae, and Perisphinctidae together compose only about one-third of the total specimens.

The Tuxedni Group has not furnished any ammonite genera that characterize the European zone of Sonninia sowerbyi at the base of the middle Bajocian. It has, however, furnished ammonites that characterize the next higher zones of Otoites sauzei and Stephanoceras humphriesianum.
