Abstract

The Lower Jurassic ammonite genus Fanninoceras McLearn hitherto considered to belong to the family Hildoceratidae Hyatt is now assigned to the Family Oxynoticeratidae Hyatt. Its age is probably early Pliensbachian. The Maude Formation of the Queen Charlotte Islands hitherto considered to be entirely Toarcian in age is shown to include upper Sinemurian and lower Pliensbachian. In the underlying Kunga Formation ?Arniotites indicate lower Sinemurian.
