After over 150 years of study, its mosaic anatomy unifying characters of both non-flying dinosaurs and flying birds has remained challenging to interpret in a locomotory context. Here, we compare new data from three Archaeopteryx specimens obtained through phase-contrast synchrotron microtomography to a representative sample of archosaurs employing a diverse array of locomotory strategies. Our analyses reveal that the architecture of Archaeopteryx's wing bones consistently exhibits a combination of cross-sectional geometric properties uniquely shared with volant birds, particularly those occasionally utilising short-distance flapping. We therefore interpret that Archaeopteryx actively employed wing flapping to take to the air through a more anterodorsally posteroventrally oriented flight stroke than used by modern birds. This unexpected outcome implies that avian powered flight must have originated before the latest Jurassic.", "doi": "10.1038/s41467-018-03296-8", "pmid": "29535376", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC5849612"}, {"db": "pii", "key": "10.1038/s41467-018-03296-8"}], "notes": [], "created": "2018-12-05T12:46:10.701Z", "modified": "2026-09-23T08:32:58.202Z"}]}
