Prognathodon (Squamata, Mosasauridae) from the Maastrichtian chalk of Denmark

[摘要] Two mosasaur tooth crowns collected from the Maastrichtian chalk sequences of Stevns Klint and Møns Klint are here assigned to Prognathodon, a mosasaur genus hitherto unknown from Denmark. Together with previous records of the mosasaurs Plioplatecarpus, Mosasaurus and Carinodens, these new finds of Prognathodon document the coexistence of four mosasaurid genera in the Danish chalk and underscore similarities to coeval assemblages from the Maastrichtian type area in the Netherlands and Belgium.
