2" Fossil Ginkgo Leaf From North Dakota - Paleocene

 
This is a beautiful fossil Gingko leaf (Ginkgo adiantoides) from the Sentinel Butte Formation of South Dakota. It is finely detailed and the light preservation contrasts well against the dark orangish-brown rock. There are lots of other plant fossils on the back of the rock.

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.
