Megalosaurus bucklandii (Dinosauria: Theropoda), the oldest named dinosaur taxon, from the Bathonian (Middle Jurassic) of England, is a valid taxon diagnosed by a unique character combination of the lectotype dentary. Abundant referred material is described and several autapomorphies are identified: ventral surfaces of first and third to fifth sacral centra evenly rounded, ventral surface of second sacral centrum bearing longitudinal, angular ridge; dorsally directed flange around midheight on… 
A new megalosaurid theropod dinosaur from the late Middle Jurassic (Callovian) of north-western Germany: Implications for theropod evolution and faunal turnover in the Jurassic
Fragmentary remains of a large, robustly built theropod dinosaur were recovered from the marine middle Callovian Ornatenton Formation of north-eastern Northrhine-Westphalia, Germany. The specimen
A Theropod Dinosaur from the Late Jurassic Cañadón Calcáreo Formation of Central Patagonia, and the Evolution of the Theropod Tarsus
TLDR
The tarsus of P. fernandezorum shows an intermediate morphology between that of basal theropods and more derived tetanurans, and indicates that a separate ossification of the ascending process of the astragalus was present in this taxon, and provides evidence that the origin of the descending process and the a stragalar body from separate oSSifications was already present at the base of Averostra.
A comprehensive anatomical and phylogenetic evaluation of Dilophosaurus wetherilli (Dinosauria, Theropoda) with descriptions of new specimens from the Kayenta Formation of northern Arizona

  • 2020
TLDR
Many characters of the axial skeleton of Dilophosaurus wetherilli are derived compared to Late Triassic theropods and may be associated with macropredation and an increase in body size in Theropoda across the Triassic-Jurassic boundary.
New theropod (Tetanurae: Avetheropoda) material from the ‘mid’-Cretaceous Griman Greek Formation at Lightning Ridge, New South Wales, Australia
TLDR
New postcranial theropod material from the early Late Cretaceous Griman Creek Formation at Lightning Ridge is reported, including an associated set consisting of two anterior caudal vertebrae and a pubic peduncle of the ilium, to which a morphologically similar partial vertebral centra from a separate locality is tentatively referred.
A New Carcharodontosaurian Theropod from the Lusitanian Basin: Evidence of Allosauroid Sympatry in the European Late Jurassic
ABSTRACT Carcharodontosaurian allosauroids were temporally restricted to the Cretaceous, being known from all land masses with the exception of Antarctica. In addition to Veterupristisaurus from
Carcharodontosaurian remains (Dinosauria, Theropoda) from the Upper Jurassic of Portugal
Abstract A new specimen of a theropod dinosaur found in the Upper Jurassic (Freixial Formation, late Tithonian) of the Lusitanian Basin is described. It corresponds to a single individual and
A Reassessment of Kelmayisaurus petrolicus, a Large Theropod Dinosaur from the Early Cretaceous of China
The Early Cretaceous fossil record of large-bodied theropods from Asia is poor, hindering comparison of Asian predatory dinosaur faunas with those from other continents. One of the few large Asian
A New Carcharodontosauria (Theropoda) from the Early Cretaceous of Guangxi, Southern China
TLDR
Cladistic analysis supports the idea that this new large‐bodied theropod dinosaur Datanglong guangxiensis is a primitive member of the Carcharodontosauria in possessing two unambiguous synapomorphies: large external pneumatic foramina and internal spaces present in the lateral surface of ilium, and a peg‐and‐socket ischiac articulation with the ilium.

TLDR
A new genus, Duriavenator, is erected to form the new combination D. hesperis, which possesses two autapomorphies of the maxilla: a deep groove on dorsal surface of the jugal process containing numerous pneumatic foramina; and an array of small foramina in the ventral part of the articular surface for the premaxilla.

TLDR
Although incompletely known, Condorraptor is the second most complete theropod from the Middle Jurassic of Gondwana and is a representative of a global radiation of basal tetanurans in the Early to Mid Jurassic.
Phylogeny of Allosauroidea (Dinosauria: Theropoda): Comparative analysis and resolution
TLDR
A core subset of allosauroids is analysed using cladistic methodology and several comparative methods and the recovered most parsimonious topology shows a strong overall match with the stratigraphical record and is much more congruent with stratigraphy than any alternative topology.
Osteology of Cryolophosaurus ellioti (Dinosauria: Theropoda) from the Early Jurassic of Antarctica and implications for early theropod evolution
TLDR
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.

The Rutland Cetiosaurus: the anatomy and relationships of a Middle Jurassic British sauropod dinosaur
TLDR
Cladistic analysis indicates that Cetiosaurus is probably the sister–taxon to the advanced neosauropod clade, and this relationship affects the distribution of particular character states that have played an important role in determining sauropod phylogeny.
