Archaeopteryx is widely accepted as being the most basal bird, and accordingly it is regarded as central to understanding avialan origins; however, recent discoveries of derived maniraptorans have weakened the avialan status of Archaeopteryx. Here we report a new Archaeopteryx-like theropod from China. This find further demonstrates that many features formerly regarded as being diagnostic of Avialae, including long and robust forelimbs, actually characterize the more inclusive group Paraves… Expand

Figures and Topics from this paper

A Jurassic avialan dinosaur from China resolves the early phylogenetic history of birds
TLDR
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. Expand
A non-archaeopterygid avialan theropod from the Late Jurassic of southern Germany
TLDR
A new, non-archaeopterygid avialan from the Lower Tithonian Mörnsheim Formation of the Solnhofen Archipelago, Alcmonavis poeschli gen. et sp. Expand
Archaeopteryx, paravian phylogenetic analyses, and the use of probability-based methods for palaeontological datasets
TLDR
This analysis demonstrates that Archaeopteryx represents a challenging taxon to place in the phylogenetic tree, but recent discoveries of derived theropods including basal avialans provide increased support for the deinonychosaurian affinities of Archaeoperyx. Expand
Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs
TLDR
Results indicate an explosive radiation of maniraptoran coelurosaurs probably in isolation in eastern Asia in the late Middle Jurassic and a rapid, at least Laurasian dispersal of the different subclades in the Late Jurassic. Expand
Palaeontology: An icon knocked from its perch
TLDR
Although the analysis is tentative, the report suggests that the authors are about to enter a new era in which Archaeopteryx is considered as distant from the ancestry of modern birds as dinosaurs such as Deinonychus. Expand
The first specimen of Archaeopteryx from the Upper Jurassic Mörnsheim Formation of Germany
TLDR
It is shown, using the first synchrotron microtomographic examination of the genus, that the eighth or Daiting specimen of Archaeopteryx possesses a character suite that robustly constrains it as a basal avialan (primitive bird), which is distinctive enough to merit designation as a new species. Expand
An unusual bird (Theropoda, Avialae) from the Early Cretaceous of Japan suggests complex evolutionary history of basal birds
TLDR
This first record of the Early Cretaceous non-ornithothoracine avialan outside of the Jehol Biota is presented and increases the understanding of their diversity and distribution during the time and provides evidence that the evolutionary history of early birds was more complex than previously realised. Expand
A new basal bird from China with implications for morphological diversity in early birds
TLDR
Phylogenetic analyses indicate that Chongmingia zhengi is basal to the dominant Mesozoic avian clades Enantiornithes and Ornithuromorpha, and represents a new basal avialan lineage. Expand
A new paravian dinosaur from the Late Jurassic of North America supports a late acquisition of avian flight
TLDR
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. Expand
New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers
TLDR
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
TLDR
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. Expand
A New Sapeornithid Bird from China and Its Implication for Early Avian Evolution
TLDR
A cladistic analysis shows that Shenshiornis possesses a skull as primitive as or even more primitive than that of Archaeopteryx and hind limbs modified for an improved arboreal capability and cursorial capability significantly weakens at the base of the Pygostylia due to a change in locomotor system. Expand
The theropod ancestry of birds: new evidence from the late cretaceous of madagascar
TLDR
Rahona has a robust, hyperextendible second digit on the hind foot that terminates in a sicklelike claw, a unique characteristic of the theropod groups Troodontidae and Dromaeosauridae. Expand
Pre-Archaeopteryx coelurosaurian dinosaurs and their implications for understanding avian origins
TLDR
Mapping some of the salient features onto a temporally-calibrated theropod phylogeny indicates that characteristics related to flight and arboreality evolved at the base of the Paraves, earlier than the Late Jurassic. Expand
New evidence concerning avian origins from the Late Cretaceous of Patagonia
TLDR
A theropod dinosaur from Patagonia is described, Unenlagia comahuensis gen. et sp. Expand
A bizarre Jurassic maniraptoran from China with elongate ribbon-like feathers
TLDR
This finding shows that a member of the avialan lineage experimented with integumentary ornamentation as early as the Middle to Late Jurassic, and provides further evidence relating to this aspect of the transition from non-avian theropods to birds. Expand
Osteology and Relationships of Byronosaurus jaffei (Theropoda: Troodontidae)
TLDR
Several interesting characters of Byronosaurus jaffei have implications both for theropod relationships and for understanding patterns of variation within coelurosaurian theropods. Expand
The earliest dromaeosaurid theropod from South America
TLDR
A near-complete, small dromaeosaurid is described that is both the most complete and the earliest member of the Maniraptora from South America and which provides new evidence for a unique Gondwanan lineage of DromaeOSauridae with an origin predating the separation between northern and southern landmasses. Expand
A basal troodontid from the Early Cretaceous of China
TLDR
The discovery of Sinovenator and the examination of character distributions along the maniraptoran lineage indicate that principal structural modifications toward avians were acquired in the early stages of manIRaptoran evolution. Expand
New Specimens of Microraptor zhaoianus (Theropoda: Dromaeosauridae) from Northeastern China
TLDR
New specimens of the diminutive theropod dinosaur Microraptor zhaoianus are described, found to be the sister taxon to other dromaeosaurs and apparently small size is primitive for Deinonychosauria, which has implications for bird origins. Expand
