One cylindrical abraded cone specimen, 2.8 cm in diameter and at least 3.0 cm long, has been found in a calcareous concretion from the Cretaceous Oyster Bay Formation (Late Campanian) of Vancouver Island, British Columbia. The cone was sectioned and peeled using the cellulose acetate peel technique. Sclerenchymatous pith is surrounded by a ring of separate secondary xylem bundles that lack resin canals. Numerous dilating resin canals occur in the inner parenchymatous cortex. The thick, sclerenchymatous outer cortical zone is covered in a dense ramentum of trichomes. Trichomes are also found on ovuliferous scale and bract bases. Vascular traces to ovuliferous scales and bracts arise independently. The bract is keeled with a terete trace and two lateral resin canals. Ovuliferous scales are sclerotic with resin canals adaxial, abaxial, and in between the vascular strands. A prominent interseminal ridge occurs between the two winged seeds of each scale. Seeds have a ridged sclerotesta; and nucellus, megagametophyte, and embryos with eight cotyledons are preserved. Cone structure most closely resembles the fossil pinaceous genus Pityostrobus. The unique features of this cone distinguish it from the known species of Pityostrobus and extant Pinaceae and emphasize the rapid evolution and diversification of the family Pinaceae that occured during the Cretaceous.
