Macroevolutionary trends in theropod dinosaur feeding mechanics
Finite element analysis is used to study the mandibles of non-avialan coelurosaurian theropods and demonstrates how feeding mechanics vary between dietary groups and major clades to reveal an overall reduction in feeding-induced stresses along all theropod lineages through time.
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.
A New Dromaeosaurid from the Late Cretaceous Khulsan Locality of Mongolia
ABSTRACT A new dromaeosaurid dinosaur, Shri devi, from the Late Cretaceous deposit of the Barun Goyot Formation at Khulsan, Mongolia, is described here. The Barun Goyot Formation (herein referred to
Archaeopteryx feather sheaths reveal sequential center-out flight-related molting strategy
Laser-Stimulated Fluorescence and fossil evidence from the oldest known bird, Archaeopteryx, are used to document the oldest record of molting, demonstrating that a sophisticated molting strategy developed unexpectedly early on in the evolution of avian flight.
Scalable total-evidence inference from molecular and continuous characters in a Bayesian framework
This work implements, benchmark and validate popular phylogenetic models for the study of paleontological and neontological continuous trait data, incorporating these models into the BEAST2 platform and illustrating and advancing the paradigm of Bayesian, probabilistic total evidence.
Laser-stimulated fluorescence reveals unseen details in fossils from the Upper Jurassic Solnhofen Limestones
Laser-stimulated fluorescence (LSF) has seen increased use in palaeontological investigations in recent years. The method uses the high flux of laser light of visible wavelengths to reveal details


The earliest dromaeosaurid theropod from South America
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.
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.
New evidence on deinonychosaurian dinosaurs from the Late Cretaceous of Patagonia
A new, Late Cretaceous member of the clade, Neuquenraptor argentinus gen. et sp.
Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs
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.
Late Cretaceous neornithine from Europe illuminates the origins of crown birds
A newly discovered fossil from the Cretaceous of Belgium is the oldest modern bird ever found, showing a unique combination of features and suggesting attributes shared by avian survivors of the end-Cretaceous mass extinction.
Description and ecologic analysis of Hollanda luceria, a Late Cretaceous bird from the Gobi Desert (Mongolia)
Abstract Avian fossils from the Upper Cretaceous of Mongolia provide significant scientific insight into the evolution of early birds, primarily due to the scarcity of continental interiors with a
European ornithomimosaurs (Dinosauria, Theropoda): an undetected record
Early Cretaceous ornithomimosaurian theropod dinosaurs have been reported from various localities in Asia, whereas they remain poorly represented and extremely rare in North America, Africa and
A taxonomic and phylogenetic re-evaluation of Therizinosauria (Dinosauria: Maniraptora)
Time calibration of ingroup relationships indicates a pre-Turonian dispersal event is needed to account for the presence of therizinosaurids in the Late Cretaceous of North America and Asia; this conclusion supports previous hypotheses of a Laurasian faunal interchange event during the Albian.
A Ceratopsian Dinosaur from the Lower Cretaceous of Western North America, and the Biogeography of Neoceratopsia
Biogeographically, A. americanus probably originated via a dispersal from Asia into North America; the exact route of this dispersal is ambiguous, although a Beringian rather than European route seems more likely in light of the absence of ceratopsians in the Early Cretaceous of Europe.
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.
