Extended Data Fig. 1: Results of our n − 1 jack-knife procedure for the mass and wing area.
From: 150 million years of sustained increase in pterosaur flight efficiency

a, b, We compared the imputed values for each species from our phylogenetic imputation procedure with the published values for mass (a) and wing area (b), for studies in which that species had been excluded from the published value. Each point represents an individual species.
