Dinosaur Tracks from the Cedar Mountain Formation (Lower Cretaceous), Arches National Park, Utah
Ichnos, 2004The seventh and largest known dinosaur tracksite from the Cedar Mountain Formation is reported from two important stratigraphic levels in the Ruby Ranch Member within the boundaries of Arches National Park. Previous reports of sites with a few isolated tracks are of limited utility in indicating the fauna represented by track makers.

Abstract Sediments of the Upper Cretaceous (Campanian) Oldman Formation at Dinosaur Provincial Park, Alberta, have yielded an exceedingly rich fauna of dinosaurs. These fluviatile sediments show characteristics of both meandering and braided channels.

Abstract Using the megaherbivorous dinosaur assemblage from the Dinosaur Park Formation as a model, linear and geometric morphometrics are applied to examine the degree to which different feeding styles—as reflected by beak morphology—facilitated the coexistence of these animals on the Late Cretaceous island continent of Laramidia.

Multiple track-bearing levels in Lower Cretaceous fluvial successions at the Houzuoshan Dinosaur Park also known as the “Junan Geological Park of Dinosaurian Relic” in Junan County, Shandong Province, China, have recently become globally famous for the unique vertebrate footprints they yield.

Hadrosaurian dinosaurs from the Maastrichtian Javelina Formation, Big Bend National Park, Texas
Journal of Paleontology, 2016AbstractRare remains of hadrosaurian dinosaurs previously reported from the Maastrichtian Javelina Formation of West Texas had been attributed tentatively to either Edmontosaurus or Kritosaurus. Three recently recovered specimens include substantial skull parts and postcranial skeletal elements sufficient to recognize three distinct hadrosaurs.

Abstract The first detailed description of the lambeosaurine Lambeosaurus magnicristatus (Ornithischia: Hadrosauridae) confirms that it is a distinct taxon characterized by its comparatively enormous cranial crest, formed predominantly by the caudodorsal process of the premaxilla, and an acute crest-snout angle. The holotype of L. magnicristatus occurs

A xiphisternal from the Dinosaur Park Formation (Campanian, Upper Cretaceous) of Alberta, Canada
Canadian Journal of Earth Sciences, 1994Xiphisternal elements of dinosaurs are only rarely recovered, probably because they seldom ossified and those that did were fragile and easily destroyed. An isolated but relatively complete, right xiphisternal element was collected from the Dinosaur Park Formation of Dinosaur Provincial Park, Alberta. It apparently contacted the left xiphisternal, the

ABSTRACT The pachycephalosaurian squamosal is one of the most diagnostic bones in this enigmatic group of dinosaurs, but little is known about variation in its morphology. Despite this, features of squamosal morphology are often used in diagnoses and phylogenetic studies.

A new, well-preserved specimen of Troodon formosus is the first to reveal the internal anatomy of the lower part of the braincase. In addition to providing new information on the brain of this highly encephalized dinosaur, the uncrushed bones clear up anatomical details left obscure by earlier studies.
