Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a review of currently the taxonomic composition and main anatomical characteristics of those theropod families closely related with early birds, with the aim to analyze and discuss main phylogenetic hypotheses that compete some topics about the non-avian dinosaur-bird transition… 

A new paravian dinosaur from the Late Jurassic of North America supports a late acquisition of avian flight

All parsimonious results support the hypothesis that each early paravian clade was plesiomorphically flightless, raising the possibility that avian flight originated as late as the Late Jurassic or Early Cretaceous.

The phylogenetic affinities and morphological peculiarities of the bird-like dinosaur Borogovia gracilicrus from the Upper Cretaceous of Mongolia

The lack of a falciform ungual, and the distinctive morphology of the second toe in B. gracilicrus are interpreted as a derived specialization among Troodontidae and not as retention of the plesiomorphic condition of non-paravian theropods.

New theropod dinosaur from the Upper Cretaceous of Patagonia sheds light on the paravian radiation in Gondwana

A new paravian from the Cenomanian-Turonian (Late Cretaceous) of Río Negro province, NW Patagonia, Argentina is found that probably constitutes a previously unknown grade in the avian-line theropods in which some flight-related adaptations of the forelimbs are present in cursorial taxa.

The early origin of a birdlike inner ear and the evolution of dinosaurian movement and vocalization

Three-dimensional morphometric analyses of a large sample of extant and extinct reptiles to investigate inner ear correlates of locomotor ability and hearing acuity revealed three vestibular morphotypes, best explained by three locomotor categories—quadrupeds, bipeds and simple fliers (including bipedal nonavialan dinosaurs), and high-maneuverability fliers.

The body plan of Halszkaraptor escuilliei (Dinosauria, Theropoda) is not a transitional form along the evolution of dromaeosaurid hypercarnivory

The halszkaraptorine bauplan is confirmed as a derived amphibious specialization, and does not represent a “transitional” stage along the evolution of dromaeosaurids.

New troodontid theropod specimen from Inner Mongolia, China clarifies phylogenetic relationships of later‐diverging small‐bodied troodontids and paravian body size evolution

A new troodontid (LH PV39) recovered from the Upper Cretaceous Wulansuhai Formation, Inner Mongolia, China, is described, highlighting the dorsoventrally compressed sacral centra. The completely

Comments on the Morphology of Basal Paravian Shoulder Girdle: New Data Based on Unenlagiid Theropods and Paleognath Birds

The present paper aims to review some important topics on pectoral girdle anatomy related to flight origins and test whether Ostrom’s ideas still remain valid under this new context, based on available phylogenetic and anatomical frameworks.

The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends

The authors' observations improve the taxonomic utility of theropod teeth and in some cases can help make isolated teeth useful as biostratigraphic markers, and should be a priority for investigations seeking to classify isolated teeth.

Osteology of Unenlagia comahuensis (Theropoda, Paraves, Unenlagiidae) from the Late Cretaceous of Patagonia

Detailed analysis of Unenlagia anatomy resulted in the recognition of one possible additional Unenlagiidae synapomorphy (i.e., the presence of cup‐like iliac articulation on ischium), lending support to the interpretation that unen lagiids are stem‐Avialae.



New evidence concerning avian origins from the Late Cretaceous of Patagonia

A theropod dinosaur from Patagonia is described, Unenlagia comahuensis gen. et sp.

Avian Ancestors-A Review of the Phylogenetic Relationships of the Theropods Unenlagiidae, Microraptoria, Anchiornis and Scansoriopterygidae.

This book presents some novel results which are important for the reconstruction of this major evolutionary transition to birds and builds one of the largest datasets for the examination of coelurosaurian phylogeny, but their focus is on several recently discovered taxa, such as Unenlagiidae, Microraptoria, Anchiornis and Scansoriopterygidae.

An integrative approach to understanding bird origins

Recent discoveries of spectacular dinosaur fossils overwhelmingly support the hypothesis that birds are descended from maniraptoran theropod dinosaurs, and furthermore, demonstrate that distinctive bird characteristics such as feathers, flight, endothermic physiology, unique strategies for reproduction and growth, and a novel pulmonary system originated among Mesozoic terrestrial dinosaurs.

A Jurassic avialan dinosaur from China resolves the early phylogenetic history of birds

The complete skeleton of a new paravian from the Tiaojishan Formation of Liaoning Province, China is described and including it in a comprehensive phylogenetic analysis for basal Paraves recovers Archaeopteryx as the basal-most avialan and implies that the early diversification of Paraves and Avialae took place in the Middle–Late Jurassic period.

Archaeopteryx and the origin of birds

Analysis of the five presently known skeletal specimens of Archaeopteryx confirm the conclusions (long rejected by most subsequent workers) of Heilmann (1926), Lowe (1935, 1944, 1944) and Holmgren (1955), namely, that the skeletal anatomy of Archaeipteryx is extraordinarily similar to that of contemporaneous and succeeding coelurosaurian dinosaurs.

The last several years have seen the discovery of many new theropod dinosaur taxa. Data obtained from these and from fragmentary forms not previously utilized in cladistic analyses are examined. An

A Review of Dromaeosaurid Systematics and Paravian Phylogeny

This study provides the most detailed and comprehensive phylogenetic analysis of paravians to date in order to explore the phylogenetic history of dromaeosaurid taxa and reviews and revises the membership of DromaeOSauridae and provides an apomorphy-based diagnosis for all valid taxa.

New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers

An analysis of the phylogenetic distribution of pennaceous feathers on the tail, hindlimb and arms of advanced maniraptorans and basal avialans strongly indicates that these structures evolved in a functional context other than flight, most probably in relation to display, as suggested by some previous studies.

A pre-Archaeopteryx troodontid theropod from China with long feathers on the metatarsus

The extensive feathering of this specimen, particularly the attachment of long pennaceous feathers to the pes, sheds new light on the early evolution of feathers and demonstrates the complex distribution of skeletal and integumentary features close to the dinosaur–bird transition.

The inclusion of the Tyrannosauridae within Maniraptora suggests a major adaptive radiation of coelurosaurs within Cretaceous Asiamerica comparable to contemporaneous radiations in various herbivorous dinosaurian clades.
