Boreiohydrias is an extinct genus of marine polymixiiform ray-finned fish, related to modern beardfish, that lived during the Turonian stage of the Late Cretaceous epoch. It is the only member of the family Boreiohydriidae.[1]
Distribution
Boreiohydrias dayi is known from the shore of Lac des Bois in the Northwest Territories, Canada, in Turonian-aged sediments 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]
