Silurian graptolites from the Cape Phillips Formation in Arctic Canada are preserved both as flattened and three dimensional specimens. This monograph describes 35 species of Wenlock graptolites, including 11 species of retiolitids. Four biozones are recognized. Diversity trends and correlation to European graptolite faunas shows that the degree of faunal provincialism changed through the Wenlock with an increase in endemism from the instrenuus-kolobus Biozone into the flumendosae Biozone.
