3.2" Fossil Cone (Parataxodium) With Ginkgo On Other Side

Fossil Cone (Parataxodium) With Ginkgo On Other Side #232006

This is a beautifully preserved, 3.2" wide fossil Ginkgo 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 are multiple seed pods preserved on the Ginkgo side of the rock, with a full fossil cone (Parataxodium sp.) on the opposite side.

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.
