Cumbaaichthys is an extinct genus of marine polymixiiform ray-finned fish that lived during the Turonian stage of the Late Cretaceous epoch. It contains a single species, C. oxyrhynchus, known from Canada. It is a basal polymixiiform of uncertain familial classification.[1]
Distribution
Cumbaaichthys oxyrhynchus is known from Turonian-aged deposits on the shore of Lac des Bois in the Northwest Territories, deposited in the aftermath of the Cenomanian-Turonian boundary event. This locality represents an open-water environment on the northern edge of the Western Interior Seaway, and is potentially correlated with the Cenomanian and Turonian-aged Slater River Formation.[1][2]
