Not ex library --- Geological Society of America Special Paper 361, edited by Joseph H. Hartman, Kirk R. Johnson, and Douglas J. Nichols. The volume gathers integrated… studies of the uppermost Cretaceous Hell Creek Formation as exposed in the Williston Basin of North Dakota, South Dakota, and Montana, drawing together newly analyzed material from western North and South Dakota with earlier work from the Fort Peck Reservoir area. Contributions address the lithostratigraphy of the Hell Creek Formation in North Dakota; magnetostratigraphy and geochronology of the Hell Creek and basal Fort Union formations; palynology and microstratigraphy of Cretaceous-Tertiary boundary sections in southwestern North Dakota, northwestern South Dakota, and central Montana; vertebrate biostratigraphy and a synopsis of the Hell Creek dinosaur assemblage; patterns of geographic variation in latest Cretaceous vertebrates; the megaflora of the Hell Creek and lower Fort Union formations in the western Dakotas; a preliminary assessment of insect herbivory across the K-T boundary; and a historical chapter on early picking of the boundary in the Williston Basin, closing with a 2001 synthesis of the formation. Topics treated include evidence for the persistence of the Western Interior Seaway and a proposed duration for Hell Creek deposition.
