The Haslam Formation is a black shale geologic formation exposed on Vancouver Island and the Gulf Islands, British Columbia, Canada. It preserves primarily marine fossils dating back to the Santonian age of the late Cretaceous period, including specimens of the elasmosaurid plesiosaur Traskasaura sandrae, and three nostoceratid turrilitoids Ainoceras boomerangense and Amapondella separoannulum.
