Fig. 9: Positions of estimated confuciusornithid specimens in a morphospace defined by wing loading (WL) and aspect ratio (AR) of extant birds with particular modes of flight.

Colored lines mark the areas of morphospace occupied by extant birds with particular modes of flight. The image of the morphospace was previously published by Serrano et al.62, and is used here with permission. Black circles indicate specimens which are holotypes of their respective species, unless only a specimen number is indicated. The specimens are numbered in descending order of estimated body mass.
