Figure 7

Analysis using the coelurosaurian matrix places Chongmingia within basal avialans and as the sister group to Ornithothoraces (p1), and analysis using the Mesozoic avian matrix resolves Chongmingia as the most basal avialan, except for Archaeopteryx (p2). See Supplementary Figs 2–4 for complete results. (The skeletal drawing and silhouettes were drawn by Min Wang).
