Description
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.
