Western North America preservers a remarkable terrestrial record of ancient ecosystems across the Cretaceous-Paleogene (K-Pg) boundary and provides an excellent framework in which to examine short and long-term changes in climate, plants, and animals change pre and post K-Pg mass extinction. These data suggest a staged and intrinsically linked pattern of extinction and recovery of plant and associated vertebrate communities.
