Abstract

Microraptorines are a group of predatory dromaeosaurid theropod dinosaurs with aerodynamic capacity. These close relatives of birds are essential for testing hypotheses explaining the origin and early evolution of avian flight. Here we describe a new 'four-winged' microraptorine, Changyuraptor yangi, from the Early Cretaceous Jehol Biota of China. With tail feathers that are nearly 30 cm long, roughly 30% the length of the skeleton, the new fossil possesses the longest known feathers for any non-avian dinosaur. Furthermore, it is the largest theropod with long, pennaceous feathers attached to the lower hind limbs (that is, 'hindwings'). The lengthy feathered tail of the new fossil provides insight into the flight performance of microraptorines and how they may have maintained aerial competency at larger body sizes. We demonstrate how the low-aspect-ratio tail of the new fossil would have acted as a pitch control structure reducing descent speed and thus playing a key role in landing.

  • The basic dromaeosaurid topology is maintained in this study, with unenlagiines and microraptorines at earlier diverging positions and eudromaeosaurians at later diverging ones.

    “The basic dromaeosaurid topology is maintained in this study, with unenlagiines and microraptorines at earlier diverging positions ( contra [67]) and eudromaeosaurians at later diverging ones [1, 2, 15, 17, 28, 30, 32].”

    From Potential for Powered Flight Neared by Most Close Avialan Relatives, but Few Crossed Its Thresholds (2020) · cites this paper as [15]

    The Description reports a monophyletic dromaeosaurid group containing Microraptorinae, and the Phylogenetic analysis says its topology matches Turner et al. Neither passage specifies the claimed earlier-diverging positions of unenlagiines and microraptorines relative to later-diverging eudromaeosaurians. (LLM, conf=0.78)

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.
