Abstract Ongoing research into the biostratigraphy of the upper Campanian Dinosaur Park Formation (DPF) of Alberta has demonstrated that megaherbivorous dinosaur taxa (ankylosaurs, ceratopsids, hadrosaurids) are not homogeneously distributed throughout the unit.

A NEW, LARGE ORNITHOMIMID FROM THE CRETACEOUS DINOSAUR PARK FORMATION OF ALBERTA, CANADA: IMPLICATIONS FOR THE STUDY OF DISSOCIATED DINOSAUR REMAINS [PDF]
Palaeontology, 2008 Abstract: Only two ornithomimid genera,OrnithomimusandStruthiomimus, are currently known from the Upper Cretaceous of North America. However, a number of ornithomimid elements from Alberta’s Dinosaur Park Formation (Upper Campanian), cannot be assigned to eitherOrnithomimusorStruthiomimus. These bones, including a frontal, caudal vertebrae, and unguals

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.

Mapping of fossil sites represents an important aspect of palaeontology, because the data collected are required for interpreting the taphonomic and depositional history of the site, as well as the palaeoecology and behavior of the organisms. Methods for mapping and documenting certain vertebrate fossil sites, such as trackways, have drastically ...

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.

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.

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

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.
