Text-fig. 3h

M a t e r i a l. USNM PAL 620025.

L o c a l i t y. Park.

D e s c r i p t i o n. Ovuliferous cone cylindrical, 5.5 cm long, 2.8 mm wide, at least 15 rows of scales, scales 1.3 cm long.

Comments on the three cones of uncertain affinity All three cones appear to lack apophyses, so they are not Pinus . It is unclear whether they represent one or multiple species.
