Abstract

The stratigraphic and paleogeographic distribution of the suspension-feeding pachycormiform fish Bonnerichthys is reviewed. Fossils attributable to this genus are known from the Western Interior Seaway (Niobrara Formation of Kansas, Sharon Springs Formation of Kansas, Nebraska, and North Dakota, DeGrey Formation of South Dakota, and possibly Mobridge Formation of Nebraska), the Eastern (Eutaw Formation of Mississippi and Mooreville and Demopolis formations of Alabama and Mississippi) and Western (Ozan Formation of Texas and Marlbrook Marl Formation of Arkansas) Gulf Coastal Plain, the Atlantic Coastal Plain (Wenonah Formation of New Jersey and possibly Marshalltown Formation of Delaware), and Pacific coast (Moreno Formation of California). Chronologically, occurrences of Bonnerichthys range in age from Coniacian to Maastrichtian. Fossils of Bonnerichthys from the Atlantic Coastal Plain, Eastern and Western Gulf Coastal Plain, and Pacific coast are definitively identified and figured here for the first time. Candidate deposits outside the United States that might yield Bonnerichthys are reviewed.
