The Anatomical Record, Volume 307, Issue 4, Page 1175-1238, April 2024.Abstract A vast array of pseudosuchian body plans evolved during the diversification of the group in the Triassic Period, but few can compare to the toothless, long‐necked, and bipedal shuvosaurids. Members of this clade possess theropod‐like character states mapped on top of more plesiomorphic pseudosuchian character states, complicating our ...

Body size distribution of the dinosaurs. [PDF]
PLoS ONE, 2012 The distribution of species body size is critically important for determining resource use within a group or clade. It is widely known that non-avian dinosaurs were the largest creatures to roam the Earth.

The Anatomical Record, Volume 307, Issue 4, Page 974-1000, April 2024.Abstract Our knowledge of the diversity and evolution of South American Triassic pseudosuchians has greatly improved in the past 15 years, due to new discoveries, but also to the revision of several historically important specimens. One of the earliest descriptions of pseudosuchians from the Triassic of Brazil stems from the classic work of Huene from ...

On Mongolian ornithopods (Dinosauria: Ornithischia). 1. Iguanodon orientalis Rozhdestvensky 1952 [PDF]
Zoological Journal of the Linnean Society, 1996 Abstract The type material of the Cretaceous ornithopod Iguanodon orientalis Rozhdestvensky, 1952 is redescribed. The characters which were originally used to establish a new species are shown to be either incorrect or indistinguishable from Iguanodon bernissartensis Boulenger, 1881.

Palaeontology, Volume 67, Issue 1, January/February 2024.Abstract Adaptation to specialist ecological niches is a key innovation that has contributed to the evolutionary success of many vertebrate clades, underpinning the acquisition of diverse skull morphologies. Dinosaurs, which dominated Mesozoic terrestrial faunas, acquired herbivory multiple times, and evolution of these herbivorous adaptations is ...

Ontogeny in the tube-crested dinosaur Parasaurolophus (Hadrosauridae) and heterochrony in hadrosaurids [PDF]
, 2013 The tube-crested hadrosaurid dinosaur Parasaurolophus is remarkable for its unusual cranial ornamentation, but little is known about its growth and development, particularly relative to well-documented ontogenetic series for lambeosaurin hadrosaurids ...

On Asian ornithopods (Dinosauria: Ornithischia). 4. ProbactrosaurusRozhdestvensky, 1966 [PDF]
Zoological Journal of the Linnean Society, 2002 The genus Probactrosaurus was first established for material discovered by a joint Russian/Chinese expedition to the Chinese autonomous region of Neimongol (Inner Mongolia). Fossils were collected at a site named Maorty (= Maortu). Material attributable to ornithopod dinosaurs was considered sufficiently distinct to permit the definition of two species
