Nipponosaurus sachalinensis(Dinosauria; Ornithopoda): anatomy and systematic position within Hadrosauridae

Journal of Vertebrate Paleontology, 2004
The hadrosaurid Nipponosaurus sachalinensis Nagao, 1936, was the first dinosaur discovered in Japan. Here we establish its ontogenetic stage, diagnostic characters, and systematic position by redescribing and phylogenetically analyzing the type and sole specimen of Nipponosaurus.

Reuniting the “head hunted” Corythosaurus excavatus (Dinosauria: Hadrosauridae) holotype skull with its dentary and postcranium

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.

A new parasaurolophin dinosaur (Hadrosauridae: Lambeosaurinae) from the Oldman Formation of southern Alberta

Canadian Journal of Earth Sciences
Lambeosaurines are abundant in the Dinosaur Park Formation of Alberta, but are poorly known from the underlying Oldman Formation (Upper Cretaceous: Campanian). A new partial skull roof and braincase from the Comrey Sandstone Zone (middle Oldman) at the Milk River Ridge Reservoir locality in southern Alberta represents the first diagnostic material of ...

The braincase and skull roof ofGryposaurus notabilis(Dinosauria, Hadrosauridae), with a taxonomic revision of the genus

Journal of Vertebrate Paleontology, 2010
ABSTRACT The facial and neurocranial anatomy of AMNH 5350, containing the most complete braincase available for Gryposaurus, is described in detail. The specimen, collected from Late Campanian outcrops of the Dinosaur Park Formation of southern Canada, is referred to G.

An ontogenetic perspective on locomotion in the Late Cretaceous dinosaurMaiasaura peeblesorum(Ornithischia: Hadrosauridae)

Canadian Journal of Earth Sciences, 2001
Ontogenetic growth in the forelimb and hindlimb of the dinosaur Maiasaura peeblesorum (Ornithischia: Hadrosauridae) from the Upper Cretaceous (Campanian-Maastrichtian) Two Medicine Formation of Montana is investigated by multivariate and bivariate morphometrics and the biomechanics of beam theory.
