Abstract. Dilophosaurus wetherilli was the largest animal known to have lived on land in North America during the Early Jurassic. Despite its charismatic presence in pop culture and dinosaurian phylogenetic analyses, major aspects of the skeletal anatomy, taxonomy, ontogeny, and evolutionary relationships of this dinosaur remain unknown. Skeletons of this species were collected from the middle and lower part of the Kayenta Formation in the Navajo Nation in northern Arizona. Redescription of the… 

A new theropod dinosaur from the early cretaceous (Barremian) of Cabo Espichel, Portugal: Implications for spinosaurid evolution

Iberospinus natarioi is recovered as a sister taxon of the clade formed by Baryonyx and Suchomimus, and outside Spinosaurinae when Vallibonaventrix cani is excluded from the analysis.

Taxonomic and phylogenetic reassessment of a large-bodied dinosaur from the earliest dinosaur-bearing beds (Carnian, Upper Triassic) from southern Brazil

The reassessment of a dinosaur specimen from Brazil, informally known as the ‘Big Saturnalia’, a supposed large-sized sauropodomorph unearthed at the ’Cerro da Alemoa’ locality in Santa Maria municipality, Rio Grande do Sul State, results in herrerasaurid affinities instead.

The anatomy and palaeobiology of the early armoured dinosaur Scutellosaurus lawleri (Ornithischia: Thyreophora) from the Kayenta Formation (Lower Jurassic) of Arizona

A detailed account of the osteology of Scutellosaurus lawleri is provided, figuring many elements for the first time, and indicates that there was considerable spatial and/or environmental variation in Early Jurassic dinosaur faunas.

Pendraig milnerae, a new small-sized coelophysoid theropod from the Late Triassic of Wales

The authors' analyses indicate that, in contrast with averostran-line neotheropods, coelophysoids underwent a small body size decrease early in their evolution, and there is ambiguous evidence to indicate that this species was subjected to dwarfism.

New specimens provide insights into the anatomy of the dinosauriform Lewisuchus admixtus Romer, 1972 from the upper Triassic levels of the Chañares Formation, NW Argentina

The cranial bones, presacral series, femur, tibia, and proximal tarsals of the new specimens match the preserved overlapping anatomy of the holotype and previously referred specimens of L. admixtus, improving the understanding of the anatomy and taxonomy of early dinosauriforms and reinforces the role of Argentinean beds on the study of the origin of dinosaurs.

New record of a stahleckeriid dicynodont (Therapsida, Dicynodontia) from the Late Triassic of southern Brazil and biostratigraphic remarks on the Riograndia Assemblage Zone

This taxonomic proposal and the lithological features of the site support that the outcrop belongs to the Riograndia Assemblage Zone (AZ), and the specimen cannot be referred unambiguously to Jachaleria candelariensis due to the lack of cranial material, it likely represents the second record of the genus in the Triassic of Brazil.

New Specimens of Scutellosaurus lawleri Colbert, 1981, from the Lower Jurassic Kayenta Formation in Arizona Elucidate the Early Evolution of Thyreophoran Dinosaurs

The ornithischians from the Kayenta Formation support a pattern of dinosaurian diversification after the end-Triassic extinction in North America, if not a broader area, that was fueled by independent northward dispersals from the southern hemisphere, supporting dispersal as an early driver of dinosaurIAN evolution.

Taxonomic, palaeobiological and evolutionary implications of a phylogenetic hypothesis for Ornithischia (Archosauria: Dinosauria)

The results find further support for the hypothesis that silesaurs comprise a paraphyletic grouping of taxa on the stem of Ornithischia and that successive silesaur taxa acquire anatomical characters anagenetically in a process that culminates in the assembly of what may be described as a ‘traditional’ ornithischian.

A Non-Averostran Neotheropod Vertebra (Dinosauria: Theropoda) from the Earliest Jurassic Whitmore Point Member (Moenave Formation) in Southwestern Utah

ABSTRACT Theropod dinosaurs are minor components of Late Triassic ecosystems in North America, comprising coelophysoids and various non-neotheropods from the Chinle Formation of Arizona, Utah,

Megalosaurus bucklandii (Dinosauria: Theropoda), the oldest named dinosaur taxon, from the Bathonian of England, is a valid taxon diagnosed by a unique character combination of the lectotype dentary, and a new phylogenetic analysis focuses on basal tetanurans, revealing several new results.

The skull of Monolophosaurus jiangi (Dinosauria: Theropoda) and its implications for early theropod phylogeny and evolution

The skull of Monolophosaurus is redescribed, which is one of the most complete basal tetanuran skulls known and the only quality source of cranial data for Middle Jurassic Chinese theropods, and several features suggest a basal position within Tetanurae, which contrasts with most published cladistic analyses.

Osteology of Cryolophosaurus ellioti (Dinosauria: Theropoda) from the Early Jurassic of Antarctica and implications for early theropod evolution

An in-depth morphological description of Cryolophosaurus is pre-sented here, along with a rigorous phylogenetic analysis of theropod relationships consisting of 347 characters and 56 taxa, in an attempt to clarify the relationships of Crylophosaurus and to provide insight into questions sur-rounding early theropid evolution.

Phylogenetic relationships of the Triassic theropod Zupaysaurus rougieri from NW Argentina

Reinterpreted, Zupaysaurus represents the first record of coelophysoids in South America and the derived features shared with Tetanurae are better interpreted as homoplasies rather than tetanuran derived features.

The anatomy and phylogenetic position of the Triassic dinosaur Staurikosaurus pricei Colbert, 1970

The phylogenetic position of S. pricei is constrained by that of its sister taxon H. ischigualastensis, which is known from much more complete material, and the absence of some characters observed in the clades Theropoda and Sauropodomorpha suggests that S.pricei is not a member of Eusaurischia.

Taxonomic and phylogenetic reassessment of the early neotheropod dinosaur Camposaurus arizonensis from the Late Triassic of North America

The holotype of Camposaurus is reassessed and identified two autapomorphies: the posterior edge of the tibial articular surface for the fibula offset as a sharp and prominent ridge and the absence of an anteriorly expanded medial condyle of the astragalus, which are considered to be a valid and diagnostic taxon of basal theropod dinosaur.

A new species of the theropod dinosaur Syntarsus from the Early Jurassic Kayenta Formation of Arizona

The discovery of Syntarsus in North America adds significantly to the increasingly detailed resemblance of African and North American Early Jurassic terrestrial vertebrate faunas.


Abstract Here we redescribe the holotype and only specimen of Segisaurus halli, a small Early Jurassic dinosaur and the only theropod known from the Navajo Sandstone. Our study highlights several

A New Megaraptoran Dinosaur (Dinosauria, Theropoda, Megaraptoridae) from the Late Cretaceous of Patagonia

Murusraptor is unique in having several diagnostic features that include anterodorsal process of lacrimal longer than height of preorbital process, and a thick, shelf-like thickening on the lateral surface of surangular ventral to the groove between the anterior surangular foramen and the insert for the uppermost intramandibular process of the dentary.

New dinosaur (Theropoda, stem-Averostra) from the earliest Jurassic of the La Quinta formation, Venezuelan Andes

Data show that the sampled summer-wet equatorial belt, which yielded the new taxon, played a pivotal role in theropod evolution across the Triassic–Jurassic boundary, as well as suggesting an earliest Jurassic maximum age for the La Quinta Formation.
