Short summary
In this study, we describe one new genus and three new species of radiolarians from Upper Cretaceous strata of the northern mainland coast of Arctic Canada. This is one of the few Cretaceous radiolarian assemblages recovered from the interior of North America and high northern latitudes and serves as a foundation for future Cretaceous radiolarian research in Arctic regions. Taxonomic descriptions were based on external and internal features observed using a scanning electron microscope.
