Cited by clades

  • Alvarezsauroidea

    Recovered Alvarezsauroidea with Therizinosauria as the first-branching maniraptorans; an ornithomimosaur sister-group topology is four steps longer.

    Nested Anchiornis with Archaeopteryx in an expanded Archaeopterygidae recovered as deinonychosaurs, rejecting a stemward paravian position at 15 steps.

  • Caudipteridae

    Recovered Similicaudipteryx as the first-branching oviraptorosaur and described basal oviraptorosaurs as a grade of short-armed taxa including Caudipteryx.

  • Compsognathidae

    Recovered only a reduced Compsognathidae, with Jehol taxa and Mirischia branching more basally.

  • Deinonychosauria

    Recovered Deinonychosauria with troodontids inside it, and found that placing troodontids closer to birds costs one step.

  • Halszkaraptorinae

    Large paravian phylogenetic analysis bearing on Halszkaraptorinae placement, contra adopted arrangement.

  • Patagonykinae

    Recovered Patagonykus and Bonapartenykus outside Alvarezsauridae, joined by Xiyunykus and Bannykus as patagonykines, though cautioning this arrangement is not heavily favored.

    Recovered Sinovenatorinae with a different membership, excluding Sinusonasus and Daliansaurus and including Xiaotingia and Jianianhualong.
