This dataset is the Supplementary Materials of the Pei, Pittman et al.
(2020) study 'Potential for powered flight neared by most close
avialan relatives but few crossed its thresholds' in Current Biology
(https://doi.org/10.1016/j.cub.2020.06.105). In this study, a revised
phylogeny of coelurosaurian theropod dinosaurs was used to reconstruct
their potential for powered flight. It found that powered flight potential
evolved at least three times (once in birds and twice in dromaeosaurids)
and that many ancestors of close bird relatives neared thresholds of
powered flight potential. The latter suggests that there was broad
experimentation with wing-assisted locomotion before theropod flight
evolved. This dataset contains an expanded version of the Theropod Working
Group (TWiG) coelurosaurian theropod phylogenetic data matrix (revised
after Brusatte et al. 2014). It also contains the script and results
associated with an automated parsimony-based phylogenetic analysis of
the data matrix. This dataset includes the wing loading and specific lift
proxy data used to reconstruct flight potential in
the pennaceous feathered pennaraptoran theropods listed in the taxon list
as well as the results of the parsimony- and maximum-likelihood based
mapping of these proxies over the reconstructed tree topology. Forelimb
length [(humerus length + ulna length)/femoral length] and body size data
are also included as well as the results of the parsimony- and
maximum-likelihood based mapping of these parameters over the same tree
topology. Please read the following files before navigating the dataset:
