Paleogeography of the Campanian

The Cerro del Pueblo Formation is a geological formation in Coahuila, Mexico, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1] The formation is believed to correlate with the Baculites reesidesi and Baculites jenseni ammonite zones, which dates it to 73.63-72.74 Ma.[2]
