Birds are among the most diverse and intensivelystudied vertebrate groups, but many aspects of theirhigher-level phylogeny and evolution still remaincontroversial. One contentious issue concerns theantiquity of modern birds (=crown Aves): the ageof the most recent common ancestor of all livingbirds (Gauthier 1986). Very few Mesozoic fossilsare attributable to modern birds (e.g., Clarke et al.2005; Dyke and Kaiser 2011; Brocklehurst et al. 2012;Ksepka and Boyd 2012) suggesting that they diversi… Expand

Hyainailourine and teratodontine cranial material from the late Eocene of Egypt and the application of parsimony and Bayesian methods to the phylogeny and biogeography of Hyaenodonta (Placentalia, Mammalia)
TLDR
It is found that Hyaenodonta most likely originated in Europe, rather than Afro-Arabia, and it is proposed that the superfamily Hyainailouroidea be used to describe this relationship. Expand
A new African Titanosaurian Sauropod Dinosaur from the middle Cretaceous Galula Formation (Mtuka Member), Rukwa Rift Basin, Southwestern Tanzania
TLDR
Both comparative morphology and phylogenetic analyses support Mnyamawamtuka as a distinct and distant relative to Rukwatitan bisepultus and Shingopana songwensis from the younger Namba Member of the Galula Formation with these results largely congruent with newly constrained ages for the Mtuka Member (Aptian–Cenomanian) and Namba Members (Campanian). Expand
A molecular genetic time scale demonstrates Cretaceous origins and multiple diversification rate shifts within the order Galliformes (Aves).
TLDR
Diversification analyses conducted on 10,000 timetrees sampled from the posterior distribution of candidate trees show that the evolutionary history of the Galliformes is best explained by a rate-shift model including 1-3 clade-specific increases in diversification rate. Expand
High evolutionary rates and the origin of the Rosso Ammonitico Veronese Formation (Middle-Upper Jurassic of Italy) reptiles
TLDR
A phase of rapid evolutionary adaptation to deeper marine environments in the ancestors of the Rosso Ammonitico Veronese reptiles as a response to the latest Liassic regressive regime in Northern Tethys is suggested. Expand
Tip-dating and the origin of Telluraves.
TLDR
The authors' analyses recover a Late Cretaceous origin for crown Telluraves, with a few lineages crossing the K-Pg boundary, and show the group underwent rapid diversification, likely benefiting from increased ecological opportunities in the aftermath of the extinction event. Expand
An advanced, new long-legged bird from the Early Cretaceous of the Jehol Group (northeastern China): insights into the temporal divergence of modern birds.
TLDR
Gansus zheni is the most advanced bird known today for the Jehol Biota and provides the best-documented case of inter-basinal correlations using low-taxonomic clades of fossil birds. Expand
A large-clawed theropod (Dinosauria: Tetanurae) from the Lower Cretaceous of Australia and the Gondwanan origin of megaraptorid theropods
Abstract Megaraptoridae comprises a clade of enigmatic Gondwanan theropods with characteristic hypertrophied claws on the first and second manual digits. The majority of megaraptorids are known from… Expand
Phylogeny, Macroevolutionary Trends and Historical Biogeography of Sloths: Insights From a Bayesian Morphological Clock Analysis.
TLDR
The phylogeny obtained supports the existence of the commonly recognized clades for the group and includes several recently described genera of sloths into an assembled morphological data supermatrix and applies Bayesian inference to 64 sloth genera. Expand
Bayesian estimation of fossil phylogenies and the evolution of early to middle Paleozoic crinoids (Echinodermata)
TLDR
Results support several clades recognized in previous analyses sampling only Ordovician taxa, but also reveal instances where phylogenetic affinities are more complex and extensive revisions are necessary, particularly among the Cladida. Expand
Inferring Arthropod Phylogeny: Fossils and their Interaction with Other Data Sources.

TLDR
The origin of mandibles exemplifies an integrative approach to analyzing the origin of a complex phenotypic feature using molecular, anatomical, and palaeontological data. Expand

Mass extinction of birds at the Cretaceous–Paleogene (K–Pg) boundary
TLDR
A diverse avifauna from the latest Maastrichtian of western North America is described, which provides definitive evidence for the persistence of a range of archaic birds to within 300,000 y of the K–Pg boundary and shows that a major radiation of Ornithurae preceded the end of the Cretaceous. Expand
The Completeness of the Fossil Record of Mesozoic Birds: Implications for Early Avian Evolution
TLDR
The quality of the fossil record of Mesozoic avian species is assessed using a recently proposed character completeness metric which calculates the percentage of phylogenetic characters that can be scored for each taxon, suggesting the abundance and diversity of birds might influence the probability of high quality specimens being preserved. Expand
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.

Multiple nuclear genes and retroposons support vicariance and dispersal of the palaeognaths, and an Early Cretaceous origin of modern birds

  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2012
TLDR
A species tree for the major palaeognath lineages is presented using 27 nuclear genes and 27 archaic retroposon insertions, showing that rheas is sister to the kiwis, emu and cassowaries, and ratite paraphyly because tinamous are sister to moas. Expand
THE MESOZOIC RADIATION OF BIRDS
TLDR
A wealth of recent discoveries combined with new phylogenetic analyses have documented the divergence of a number of lineages by the beginning of the Cretaceous, providing insights into the evolutionary development of feathers and other important features of the avian flight system. Expand
A redescription of Chaoyangia beishanensis (Aves) and a comprehensive phylogeny of Mesozoic birds
TLDR
Unique among ornithurines, Chaoyangia possesses two dorsal processes on the ischium, and thus remains a valid taxon and is included in a cladistic analysis to test morphological hypotheses regarding its systematic position. Expand
THE AFFINITIES OF THE ENIGMATIC DINOSAUR ESHANOSAURUS DEGUCHIIANUS FROM THE EARLY JURASSIC OF YUNNAN PROVINCE, PEOPLE’S REPUBLIC OF CHINA
TLDR
Detailed consideration of the holotype specimen suggests that several features of the dentary and dentition exclude Eshanosaurus from Sauropodomorpha and support its inclusion within Therizinosauroidea. Expand
Definitive fossil evidence for the extant avian radiation in the Cretaceous
TLDR
A rare, partial skeleton from the Maastrichtian of Antarctica is identified as the first Cretaceous fossil definitively placed within the extant bird radiation, and phylogenetic analyses supported by independent histological data indicate that a new species, Vegavis iaai, is a part of Anseriformes (waterfowl) and is most closely related to Anatidae, which includes true ducks. Expand
The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
TLDR
A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).
