Abstract
Tegan Beveridge studied weathered volcanic ash horizons within Late Cretaceous rocks in western North America. New high-precision ages and geochemical data facilitated correlation of richly fossiliferous rock units across the continent. Refined understanding of these rocks has implications for investigating dinosaur biogeography and Late Cretaceous ecosystems from Alberta to Mexico.
