A complete skull of Ichthyodectes ctenodon (Ichthyodectidae) and scattered remains of small individuals of the same genus together with Holcolepis (Elopidae), are recorded in association from Cretaceous sediments on the western shore of Lac des Bois, Northwest Territories. The strata are probably of Albian–Cenomanian age, this being based on the fish evidence. The occurrence of this association in the far north of Canada was previously unknown and provides fresh evidence of freedom of nektonic movement in the Cretaceous Mediterranean – North American seaways.
