2.45" Fossil Leaf (Rhamnus?) Nodule - Hell Creek

This is a beautiful 2.45" fossil leaf nodule (Rhamnus sp.?) from the Late Cretaceous Hell Creek Formation on our partner's private quarry in Bowman, North Dakota. It is preserved inside a sandstone concretion.

The Rhamnus genus of trees contain modern buckthorns. They were common understory trees and shrubs throughout the Hell Creek area during the Late Cretaceous. Two species have been described out of the formation: R. cleburnii and R. salicifolius.

Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically studied areas in the world. 158 genera of animals and 64 genera of plants are known from the formation and new discoveries are made frequently. In addition to Tyrannosaurs, Ceratopsids, and Hadrosaurs, the formation has yielded remains of amphibians, reptiles, lizards, snakes and turtles, fish and sharks, avian and non-avian dinosaurs, and mammals. The Hell Creek Formation gives the most complete understanding of the environment just before the Cretaceous-Paleogene extinction.
