Ginkgo biloba Leaf
Age: Paleocene
Formation: Sentinnel Butte Formation
Location: Almont, North Dakota

Here is a very unusual fossil Ginkgo leaf. This is a split pair Ginkgo biloba leaf (formerly G. adiantoides) from the Paleocene of North Dakota. This fossil leaf is complete and preserves fine detail. The leaf has great form, and the palmate venation of the Ginkgo leaf is wonderfully displayed (difficult to see in photo). This specimen has a long petiole preserved, which is quite unusual. The off-white color of the leaf contrasts beautifully with the dark brown matrix. The leaf is well centered on both plates of matrix that also contains some other plant fossils. This is an extremely rare split pair Ginkgo leaf from North Dakota.
