14.7" Fossil Ginkgo Plate From North Dakota - Paleocene
This is a plate of ten beautiful fossil Gingko leaves (Ginkgo adiantoides) from the Sentinel Butte Formation of South Dakota. They are finely detailed and the light preservation contrasts well against the dark orangish-brown rock. Comes with a gibson display stand.
During this time on the Paleocene epoch the Ginkgo genus was only represented by a single polymorphic species, 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. The species Ginkgo adiantoides went extinct approximately 7 million years ago.
