Cited by genera

• Coelurus

  Phylogenetic reanalysis recovering Coelurus fragilis as basal-most ornithomimosaur under equal-weight parsimony; authors note this does not settle the longstanding placement ambiguity.

• Deltadromeus

  Recovered Deltadromeus within Ornithomimosauria, alongside Gualicho.

• Gualicho

  New matrix recovers Gualicho as an early-branching ornithomimosaur alongside Deltadromeus

• Mirischia

  Recovered Mirischia among earliest-branching Maniraptoromorpha with Tanycolagreus and Santanaraptor.

• Santanaraptor

  Recovered Santanaraptor as an early megaraptoran within Tyrannosauroidea under equal weights, and as an earliest-branching maniraptoromorph under implied weights, the preferred result.

• Tanycolagreus

  Recovered Tanycolagreus among earliest-branching Maniraptoromorpha with Santanaraptor and Mirischia.
