    Archaeopteryx feather sheaths reveal sequential center-out flight-related molting strategy by Thomas G. Kaye, Michael Pittman, William R. Wahl

    Published 2020-12-01

    Reassessment of the wing feathers of Archaeopteryx lithographica suggests no robust evidence for the presence of elongated dorsal wing coverts. by Robert L Nudds

    Published 2014-01-01
    “…Recently it was proposed that the primary feathers of Archaeopteryx lithographica (HMN1880) were overlaid by long covert feathers, and that a multilayered feathered wing was a feature of early fossils with feathered forelimbs. …”

    Air-filled postcranial bones in theropod dinosaurs: physiological implications and the 'reptile'-bird transition. by Benson, R, Butler, R, Carrano, M, O'Connor, P

    Published 2012
    “…We review recent work on the significance of pneumaticity for understanding the biology of extinct ornithodirans, and present detailed new data on the proportion of the skeleton that was pneumatised in 131 non-avian theropods and Archaeopteryx. This includes all taxa known from significant postcranial remains. …”

    Reconsidering the Avian Nature of the Oviraptorosaur Brain (Dinosauria: Theropoda). by Amy M Balanoff, G S Bever, Mark A Norell

    Published 2014-01-01
    “…The existence of such features has implications for the transformational history of avian neuroanatomy and suggests that the oviraptorosaur radiation is a product of the immediate stem lineage of birds-after the divergence of Archaeopteryx lithographica. Results derived from an expanded comparative sample indicate that the strong endocranial similarity between Conchoraptor and modern birds largely reflects shared conservation of plesiomorphic features. …”

    Homology and Potential Cellular and Molecular Mechanisms for the Development of Unique Feather Morphologies in Early Birds by David J. Bottjer, Hailu You, Cheng-ming Chuong, Luis M. Chiappe, Jingmai K. O’Connor

    Published 2012-09-01
    “…The early stepwise evolution of apparently modern feathers occurred within Maniraptora, basal to the avian transition, with asymmetrical pennaceous feathers suited for flight present in the most basal recognized avian, Archaeopteryx lithographica. The number of extinct primitive feather morphotypes recognized among non-avian dinosaurs continues to increase with new discoveries; some of these resemble feathers present in basal birds. …”
