The Grand Staircase-Escalante nationwide Monument is the site of 1 of the best-known terrestrial files for the overdue Cretaceous. past fieldwork proven the richness of the world, yet a huge attempt started within the new century has documented over 2,000 new vertebrate fossil websites, supplied new radiometric dates, and pointed out 5 new genera of ceratopsids, new species of hadrosaur, a possible new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, a number of different types of theropods (including a brand new genus of oviraptor
and a brand new tyrannosaur), plus the main entire specimen of a overdue Cretaceous therizinosaur ever gathered from North the United States, and masses extra. The study documented during this booklet is rewriting our realizing of past due Cretaceous paleobiogeography and dinosaur phyletics. on the most sensible of the Grand Staircase: The past due Cretaceous of Southern Utah is an enormous stepping stone towards a complete synthesis of the ecology and evolution of the overdue Cretaceous ecosystems of western North the USA.

Sample text

One of the most obvious features of the region’s Cretaceous record are lithologic macrocycles first pointed out by Peterson (1969a), then analyzed in detail by Little (1997). 8. Chronostratigraphic relationships of Cretaceous units in southern Utah. Stratigraphic units are compressed upsection because of regularly spaced time axis and no vertical thickness is implied. Vertical rule indicates unconformity. PER, period; PALEOG, Paleogene; STA, stage; M, Maastrichtian; Sa, Santonian; Co, Coniacian; Tur, Turonian; Cen, Cenomanian; Tithon, Tithonian; Upp, upper; Mid, middle; MP, Markagunt Plateau; PP, Paunsaugunt Plateau; KB, Kaiparowits Basin; HB, Henry Basin.

A wide variety of small and large vertebrates, including sharks, bony fish, marine turtles, plesiosaurs, and a nearly complete theropod dinosaur have been documented (Gillette, Hayden, and Titus, 1999; Albright, Gillette, and Titus, 2007a, 2007b, this volume, Chapter 25; Schmeisser and Gillette, 2009). Vertebrate material appears to be more common in the lower portion of the lower Turonian part of the section where depositional rates were lowest, but plesiosaurs and other large vertebrates occur throughout the section.
