Phylogenetic relationships among modern birds (Neornithes): towards an avian tree of life
Modem perceptions of the inonophyly of avian higher taxa {modern birds, Neomiihes) and their interrelationships are the legacy uf systematic work undertaken in the 19th century. Before LlieExpand
Vertebrate assemblages from the early Late Cretaceous of southeastern Morocco: An overview
Fossils of vertebrates have been found in great abundance in the continental and marine early Late Cretaceous sediments of Southeastern Morocco for more than 50 years. About 80 vertebrate taxa haveExpand
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. Expand
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
Suprageneric relationships of galliform birds (Aves, Galliformes): a cladistic analysis of morphological characters
Although there are a number of important differences, especially with regard to relationships within the nonquail phasianoids, the results of this morphological phylogenetic analysis are broadly congruent with traditional classifications and existing molecular hypotheses of galliform phylogenetic relationships.

Reduced plumage and flight ability of a new Jurassic paravian theropod from China.
A basal troodontid from the Tiaojishan Formation that resembles Anchiornis is reported that increases the known diversity of small-bodied dinosaurs in the Jurassic, shows that taxa with similar body plans could occupy different niches in the same ecosystem and suggests a more complex picture for the origin of flight.

A reversal of fortunes: climate change ‘winners’ and ‘losers’ in Antarctic Peninsula penguins
Current climate warming has decoupled historic population responses in the Antarctic Peninsula, favoring generalist gentoo penguins as climate change ‘winners’, while Adélie and chinstrap penguins have become climate change 'losers’. Expand
Calibration of galliform molecular clocks using multiple fossils and genetic partitions.
Divergence time estimates indicate that the early history of Galliformes took place in the Cretaceous, including the origin of the basal-most megapode and perhaps cracid lineages, but that the remaining morphological diversification likely started in the earliest Tertiary. Expand
The skull of the giant predatory pliosaur Rhomaleosaurus cramptoni: implications for plesiosaur phylogenetics
The first phylogenetic analysis dedicated to in-group relationships of pliosaurs allows us to hypothesise a number of well-supported lineages that correlate with marine biogeography and the palaeoecology of these reptiles. Expand
A new Enantiornithine bird from the Late Cretaceous of the Gobi desert
The combination of phylogeny and functional interpretation suggests that this new fossil bird is a representative of a flightless lineage, providing the first evidence of a trend towards more limited flying capabilities among Enantiornithes, a group of Cretaceous birds otherwise believed to be represented by competent fliers.
