1.7" Fossil Ginkgo Leaf With Seed Pods - North Dakota

Fossil Ginkgo Leaf With Seed Pods - North Dakota #198428

This is a beautiful fossil Ginkgo leaf (Ginkgo cranei) and seed pods from the Sentinel Butte Formation of North Dakota. The fossils are finely detailed and the light preservation contrasts well against the dark orangish-brown rock. It 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 at the time. Its leaves were virtually indistinguishable from modern-day Ginkgo biloba. These species of Ginkgo went extinct approximately 7 million years ago.
