2.8" Fossil Leaf (Glyptostrobus?) Nodule - Hell Creek
This is a 2.8" fossil leaf nodule (Glyptostrobus sp.?) from the Late Cretaceous Hell Creek Formation on our partner's private quarry in Bowman, North Dakota.
The Hell Creek Formation produces many fossils of coniferous plants, ranging from Auracaria (monkey puzzle) to redwoods, sequoias, and bald cypresses. One such group was the genus Glyptostrobus, similar to dawn redwoods and bald cypresses. Today, Glyptostrobus only contains one species, native to eastern Asia, but the genus contained several species that existed as far back as the Late Cretaceous in North America. Successive continental drift and ice ages separated the modern G. pensilis from its now extinct relatives.

The Hell Creek Formation
Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
