S3 Text-fig. 3o M a t e r i a l. 620785, 776563, 776568. L o c a l i t y. Park. D e s c r i p t i o n. Winged seed linear, 9.7 mm long, 4.0 mm wide; seed body on proximal side, elliptical, 3.5 mm long and 1.8 mm wide; base of seed body is tilted towards the abmedial side; wing widest in the middle; wing has bold, undulating striations. R e m a r k s. Pinus sp. S3 differs from Pinus sp. S1 and Pinus sp. S2 by having a seed body that is tilted towards the abmedial side and stronger striations on the wing. Because the seed body has completely disarticulated from the wing, we are unable to classify it based on Wolfe and Schorn’s (1990) schema.
