Age: Paleocene
Formation: Sentinnel Butte Formation
Location: Almont, North Dakota
Size: Leaf is 2.9 inches long
Here is a very detailed fossil Ginkgo leaf. This is Ginkgo biloba (formerly G. adiantoides) from the Paleocene of North Dakota. This fossil leaf is quite large 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 the large plate of matrix. This is one of the more complete Ginkgo leaves we have ever been able to offer.
