Caletodraco cottardi: A New Furileusaurian Abelisaurid (Dinosauria: Theropoda) from the Cenomanian Chalk of Normandy (North-Western France)

Fossil Studies
An articulated group of skeletal elements comprising a sacrum, both ilia and a first caudal vertebra, plus an isolated tooth found in immediate proximity to the bones, from the lower Cenomanian Chalk at Saint-Jouin-Bruneval (Seine-Maritime, Normandy ...

Appendicular osteology of Skorpiovenator bustingorryi (Theropoda, Abelisauridae) with comments on phylogenetic features of abelisaurids

Journal of Systematic Palaeontology, 2022
Skorpiovenator bustingorryi is a derived abelisaurid theropod represented by a fairly complete skeleton from the Late Cretaceous sedimentary beds of north-western Patagonia.

Phylogenetic taxonomy of the Coelurosauria (Dinosauria: Theropoda)

Journal of Paleontology, 1996
Phylogenetic taxonomy, that component of phylogenetic systematics concerned with the verbal representation (rather than the reconstruction or estimation) of phylogenetic relationships, was developed by de Queiroz and Gauthier (1990, 1992, 1994). Under phylogenetic taxonomy, all taxon names are names of clades (i.e., an ancestor and all of that ancestor'

Opinion 2511 (Case 3815) – Tyrannosauridae Osborn, 1906 (Dinosauria, Theropoda): usage conserved by reversing precedence with Deinodontidae Cope, 1866 and Dryptosauridae Marsh, 1890

Bulletin of Zoological Nomenclature
. The International Commission on Zoological Nomenclature has used its plenary power to conserve the family-group name Tyrannosauridae Osborn, 1906 by giving it precedence over Deinodontidae Cope, 1866 and Dryptosauridae Marsh, 1890 whenever it is ...

Preliminary Study on the Reconstruction and Function of the Hyperelongate Neural Spines in the Dorsal Vertebrae of Deinocheirus mirificus (Theropoda: Ornithomimosauria)

Transactions on Social Science, Education and Humanities Research
Deinocheirus is a bizarre and unique theropod dinosaur. The holotype of Deinocheirus was discovered in 1976, but its characteristics and phylogenetic position remained largely enigmatic due to the scarcity of fossil material.

Did oviraptorosaurs (Dinosauria; Theropoda) inhabit Argentina?

Cretaceous Research, 2007
Abstract In this contribution a putative oviraptorosaurian cervical vertebra discovered in the Campanian-Maastrichtian El Brete Formation from Salta Province, NW Argentina is analysed. Based on the resemblances of this vertebra with those of the basal neoceratosaurian Elaphrosaurus and with the noasaurid Noasaurus , the Salta specimen is ...

Osteohistology ofConfuciusornis sanctus(Theropoda: Aves)

Journal of Vertebrate Paleontology, 2003
ABSTRACT An analysis of 80 thin-sections of the long bones of a relatively large and presumably adult specimen of Confuciusornis sanctus, a basal bird from the Early Cretaceous of China, reveals osteohistological patterns similar in some ways to those of extant birds of approximate size, but different in other ways.

Mandibular biomechanics of Acheroraptor temertyorum (Theropoda: Dromaeosauridae) with implications for the feeding ecology and behaviour

Mesozoic
Acheroraptor temertyorum is a dromaeosaurid theropod, probably a saurornitholestine, found in the upper Maastrichtian Hell Creek Formation of Montana.

Forelimb musculature and function in the therizinosaur Nothronychus (Maniraptora, Theropoda)

Journal of Anatomy, 2021
AbstractTherizinosaurs are unusual theropods from the Upper Cretaceous of Asia and North America. North American representatives include Falcarius utahensis from central Utah, Nothronychus mckinleyi from west central New Mexico, and N. graffami from southern Utah. Nothronychus was quite large, with well‐developed forelimbs and pectoral girdle.

A bizarre, humped Carcharodontosauria (Theropoda) from the Lower Cretaceous of Spain

Nature, 2010
Carcharodontosaurs were the largest predatory dinosaurs, and their early evolutionary history seems to be more intricate than was previously thought. Until recently, carcharodontosaurs were restricted to a group of large theropods inhabiting the Late Cretaceous Gondwanan land masses, but in the last few years Laurasian evidence has been causing a ...
