Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The challenges in reconciling Archaeopteryx's dromaeosaurid-like pectoral morphology with the modern avian dorsoventral flight stroke exemplify that avian powered flight may have worked through alternative configurations in the past.

    “Such challenges in reconciling Archaeopteryx’s dromaeosaurid-like pectoral morphology30 with the modern avian dorsoventral flight stroke exemplify that avian powered flight may have worked through alternative configurations in the past.”

  • Archaeopteryx's large coracoids and robust, flattened and more dorsally positioned furcula lacking hypocleidial communication with the sternum could have provided support for an anterodorsally-posteroventrally oriented flight stroke cycle that was morphologically closer to the grabbing motion of maniraptorans and did not or hardly extend over the dorsum.

    “Archaeopteryx’s large coracoids30 and robust, flattened and more dorsally positioned furcula lacking hypocleidial communication with the sternum2 could have provided support for an anterodorsally-posteroventrally oriented flight stroke cycle that was morphologically closer to the “grabbing” motion of maniraptorans25 and did not or hardly extend over the dorsum.”

  • Earlier conclusions that Archaeopteryx was capable of active flight have not received universal support, largely because three skeletomorphological conditions considered essential for a functional avian flight stroke were not yet present in Archaeopteryx.

    “Earlier conclusions that Archaeopteryx was capable of active flight26 have not received universal support, largely because three skeletomorphological conditions considered essential for a functional avian flight stroke (ossified, keeled sternum; supracoracoideal “pully” arrangement; glenohumeral tolerance permitting supradorsal humeral abduction) were not yet present in Archaeopteryx26–30.”

  • The development of dorsoventral flapping is primitive for Ornithothoraces and approximately coincided with the appearance of the avian alula.

  • The origin of the modern avian flight stroke was conceivably promoted by selective pressure towards vertical take-off, which contributed to the prosperous avian radiation that continued ever since.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
