Table 5 Posterior probabilities predicting longipterygid diet by LDA and DAPC from MA and functional index data from avian upper jaws. Values with green backgrounds are more likely, values with red backgrounds are less likely. Hard/medium invertivory and generalist feeding are likely in all longipterygids, followed by scavenging and piscivory. Hard frugivory is represented only by Steatornis caripensis when semi-specialists are excluded, so no predictions are made for FrugivoreH with semi-specialists excluded. lg teeth and sm teeth Longipteryx refer to the large-toothed and small-toothed morphotypes of Longipteryx, respectively. Diet abbreviations: FrugivoreH hard frugivore, FrugivoreS soft frugivore, GranivoreS swallowing granivore, GranivoreH husking granivore, InvertivoreH hard invertivore, InvertivoreM medium invertivore, InvertivoreS soft invertivore, Tetra Hunt tetrapod hunter
