6.3" Wide Multiple Fossil Ginkgo Leaf Plate - North Dakota
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.
