Extended Data Fig. 5

Extant arboreal taxa Hylocichla mustelina (a) and Cyanocitta cristata (b); terrestrial taxon Coturnix coturnix (c-d); raptorial taxon Buteo jamaicensis (e-f). Fossil taxa represented by (g-h) enantiornithine indet. HPG-15-1 (Xing et al., 2017); (i-j) Archaeopteryx FMNH PA 830; and (k) Microraptor STM5-109 (Pittman et al. 40). All extant specimens represent recently deceased individuals being prepared for the skeletonization at the Field Museum and thus lack catalog numbers. All extant bird photos by A. D. Clark.
