Duck-billed dinosaur remains (Hadrosauridae) from the Yalovach Formation (Lower Santonian) of the Isfara 2 and Kansai localities (northern Tajikistan) are described. Most of them belong to a flat-headed hadrosaurid which is distinguished from all other representatives of the family by the absence on the frontals of a facet for the nasals.

The Distribution of Ankylosauridae, Hadrosauridae, and Ceratopsidae Dinosaurs Across Alberta
2021Hello! I am a WISEST Summer Research Program student, and I was placed in the Dino Lab. The Focus of my research project this summer was looking at the distribution of dinosaurs across Alberta - specifically three different families of herbivores. The maps in this project show a general distribution of where specimens have been found across Alberta ...

Evidence for the presence of nasal salt glands in the Hadrosauridae (Ornithischia)
Journal of Arid Environments, 1981The subcutaneous nasal glands of some Recent reptiles and birds, mainly secreting salts of sodium and potassium, are sometimes contained within depressions in the skull; they lie above or in front of the orbit. Similar preorbital or circumnarial depressions in the skull of certain ornithischian dinosaurs (Hadrosaurinae) and lateral chambers within the ...

The Palatal Structure of some Canadian Hadrosauridae (Reptilia: Ornithischia)
Canadian Journal of Earth Sciences, 1972Two distinct hadrosaurian lineages can be delineated, each showing changes from possible hypsilophodont ancestors. The Hadrosaurinae are typified by moderately vaulted palates, broad pterygoid flanges, large anterior maxillary processes, and non-folded premaxillae, with direct narial passages.

Cretaceous Research, 2017
A Corythosaurus skull (UALVP 13) was collected in 1920 from what is now Dinosaur Provincial Park in southern Alberta, Canada and was designated the holotype of Corythosaurus excavatus, a new hadrosaur species by Gilmore (1923). In 1992, a previously uncovered, weathered, headless skeleton was found.

Acta Geologica Sinica - English Edition, 2011
Abstract:On the basis of the taphonomy, osteological anatomy and ontogenetic variation, Zhuchengosaurus maximus Zhao et al., 2007 is considered to be synonymic with Shantungosaurus giganteus Hu, 1973 herein. This paper also deals with the life behavior of S. giganteus and the environment in which S. giganteus lived. S.

The Palatal Structure of some Canadian Hadrosauridae (Reptilia: Ornithischia): Discussion
Canadian Journal of Earth Sciences, 1973phus osborni may be from the Cretaceous at Edmonton; nothing else can he deduced concerning the ages or localities for these four spccies and nothing at all for the other five species discussed. The abstract includes the statement "Two distinct hadrosaurian lineages can be delineated, each showing changes from possible hypsiIophodont ancestors ...
