    • Three structurally preserved conifer ovulate cones are described from Pliocene sediments at Ch'ijee's Bluff on the Porcupine River, near Old Crow, Yukon Territory, Canada. Cones are ovoid to conical, symmetrical, 3.4–4.4 cm long and 2.8–3.4 cm wide, with helically arranged cone‐scale complexes. Ovuliferous scales are thin at the base, expanded at the apex, 2 cm long and 1 cm wide, with flat, rhomboidal apophyses and minute dorsal umbos. Pith is parenchymatous with scattered sclerenchyma at its… CONTINUE READING
