Cover Story: The Hell Creek Formation of North America is one of the few terrestrial units which preserve the K–Pg boundary. It is famous for its dinosaur fossils, such as Triceratops and Tyrannosaurus, which disappear at the K–Pg boundary mass extinction at the upper formational contact. This paper reviews the stratigraphy of the Hell Creek and implements a sequence stratigraphic framework to aid in regional correlations. Revisions suggest that the Hell Creek Formation probably represents ~700 k. y. of deposition. This image shows the basal formational contacts and depositional sequence boundaries in a typical section exposed near Fort Peck Lake, Montana. View this paper
