Pl. 9, Fig. 12

Leaf simple, ovate, 12 mm long and 11 mm wide, apex incomplete, probably acute to shortly acuminate, base slightly asymmetric cordate, margin irregularly double serrate, teeth relatively big, acute, sinus angular, venation craspedodromous, midrib straight, moderate, zig-zag in basal part, secondary veins subopposite in basal part and alternate, thinner, straight, regularly spaced, at angles of 35–50°, in 6 pairs, tertiary veins alternate percurrent, straight, often forked, venation of the higher orders regular polygonal reticulate, areolation well developed, 4-sided.

This rounded betuloid leaf is characterized by fan-like dense craspedodromous secondary veins and densely double serrate margin. We have not found any particular fossil species clearly identifiable with this specimen and cannot rule out other generic affinities.
