The fossils here described were collected from the Lai Yuan, Hebei Province in
north China. Well-preserved plant parts are cones of Pinus, identified as Pinus prototabulaeformis sp. nov. The species is different from other taxa of Pinus by larger
cones and scales. The size of the cone is a reliable diagnostic character in the group:
The large cone and scale indicate rather an arid climate in Summer in the region
where the fossils are discovered.
The age of bearing-beds is considered Upper Eocene-Lower Oligocene.
Diagnosis: Cones ovate in general outline, 8.5 cm long, 4.5 cm in diameter. Seed
scales oblong, 2—2.5 cm long, 0.8—1.1 cm wide. Apophysis obviously fattened andthickned, convex, compressed rhomboid, rostrate at the apical part of seed-bract.
