Description

Gingko Leaf
Ginkgo adiantoides
Paleocene
Sentinel Butte Formation
Morton County, North Dakota
5.00 x 4.92 x 1.14 inches (12.70 x 12.50 x 2.90 cm)

This winnowing fan-shaped fossil leaf, obviously, comes from a Gingko, and the botanical remnant has a part of the stem protruding from the broad example. The specimen requires a close look as the contrast between the rust-colored matrix and the orangey leaf is not sharp. However, the gray-blue brushstrokes of the delicate venation are extremely fine and come through the otherwise fairly monochromatic plate.

[Scale: 1 inch, with mark at 1 cm]
