Paul and Zheng et al. challenge our conclusions regarding the flight of Confuciusornis and Archaeopteryx, which derive from our method of assessing flight ability from estimated feather strength. They suggest that our mass and rachis data for these fossil birds are incorrect. Neither comment, however, invalidates our method nor alters conclusions of poor flight ability based upon our original data. We encourage researchers to use our method before critiquing our conclusions regarding early bird… Expand
A NEW METHOD TO CALCULATE PALAEOGRAVITY USING FOSSIL FEATHERS
TLDR
Values for gravity which would enable these birds to fly with weaker feathers are calculated based on the controversial theory that palaeogravity was less and are compared with earlier estimates of palAEogravity derived from a range of other life forms from approximately the same time period. Expand
Reassessment of the Wing Feathers of Archaeopteryx lithographica Suggests No Robust Evidence for the Presence of Elongated Dorsal Wing Coverts
TLDR
The qualitative arguments forwarded in support of the elongated covert hypothesis are neither robust nor supported quantitatively, and it is premature to conclude unequivocally that the wing of Archaeopteryx consisted of primary feathers overlaid with elongated coverts. Expand
Barb geometry of asymmetrical feathers reveals a transitional morphology in the evolution of avian flight
TLDR
The findings suggest that the fully modern avian flight feather, and possibly a modern capacity for powered flight, evolved crownward of Confuciusornis, long after the origin of asymmetrical flight feathers, and much later than previously recognized. Expand
Aerodynamics from Cursorial Running to Aerial Gliding for Avian Flight Evolution
Among the different models that have been proposed to explain the origin of avian flightfrom terrestrial predators, the cursorial and arboreal hypotheses remain the most discussed.However, the fossilExpand
Remarks on the evolution of the avian sternum, dinosaur gastralia, and their functional significance for the respiratory apparatus
TLDR
It is shown that sternal elements were indeed present in the stem line throughout the evolutionary transformation from non-avian theropod dinosaurs to modern birds and a trade-off between sternal Elements and gastralia, dermal bones of the belly wall that at least partially overlapped with the respiratory functions of the sternum.

Response to comments by C. Palmer on my paper, Feather structure, biomechanics and biomimetics: the incredible lightness of being
TLDR
The paper reviews the overall design principles in the feather rachis and elaborates upon recent functional interpretations and considers the validity of a study purporting to use quantitative methods and engineering principles to show that the iconic fossil bird Archaeopteryx was incapable of flapping flight.

Recent advances on the functional and evolutionary morphology of the amniote respiratory apparatus

  • Biology, Medicine
  • Annals of the New York Academy of Sciences
  • 2016
TLDR
This review focuses on some of the latest advancements that morphological research has added to understanding of how the respiratory apparatus of the primarily terrestrial vertebrates (amniotes) works and how it evolved. Expand

Comment on “Narrow Primary Feather Rachises in Confuciusornis and Archaeopteryx Suggest Poor Flight Ability”
TLDR
The authors' measurements of Confuciusornis specimens suggest that their conclusions need to be further evaluated, and that the primary feathers of these two basal birds were too weak to support sustained flight. Expand
Narrow Primary Feather Rachises in Confuciusornis and Archaeopteryx Suggest Poor Flight Ability
TLDR
Analysis of the flight feathers of early Mesozoic birds Archaeopteryx and Confuciusornis shows that the rachises were much thinner and weaker than those of modern birds, and thus the birds were not capable of flight. Expand
Life history of a basal bird: morphometrics of the Early Cretaceous Confuciusornis
TLDR
A multivariate morphometric study involving measurements of more than 100 skeletons of C. sanctus shows any correlation between size distribution and the presence or absence of blade-like rectrices (tail feathers), thus implying, that if these feathers are sexual characters, they are not correlated with sexual size dimorphism.
