At the Top of the Grandstaircase: the Late Cretaceous of Southern Utah SH-4C Gunnison and Albert CarringtonThe Grand Staircase Escalante National Monument in Utah is the location of one of the best known terrestrial records for the late Cretaceous. A major effort in the new century has documented over 2,000 new vertebrate fossil sites, provided new radiometric dates, and identified five new genera of ceratopsids, two new species of hadrosaur, a probable new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, several kinds of theropods
