Boreiohydrias
Extinct genus of fishes
From Wikipedia, the free encyclopedia
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 confirmed member of the family Boreiohydriidae, although a second potential freshwater boreiohydriid is known in Elnorichthys from the Maastrichtian of Alberta.[1][2]

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][3]
