1.9" Fossil Ginkgo Leaf From North Dakota - Paleocene

This is a beautiful fossil Gingko leaf (Ginkgo cranei) from the Sentinel Butte Formation of North Dakota. It is finely detailed and the light preservation contrasts well against the dark orangish-brown rock. There is an unidentified seed pod that's naturally associated with the gingko leaf. It's split in half, revealing the quartz crystal lined pocket within.

Comes with an acrylic display stand.

During this time in the Paleocene epoch, the Ginkgo genus was only represented by a single polymorphic species, formerly described as Ginkgo adiantoides. In 2012, the taxon Ginkgo cranei was assigned in place of Ginkgo adiantoides. This species was distributed in much of the Northern regions of North America which had a hot, humid climate. It's leaves were virtually indistinguishable from modern-day Ginkgo biloba. These species of Ginkgo went extinct approximately 7 million years ago.
