1 TEM images of the crural feathers sampled in Eoconfuciusornis STM (A and B, sample 111) compared with that of a black feather from G. gallus (C and D). TEM images of the crural feathers sampled in Eoconfuciusornis STM (A and B, sample 111) compared with that of a black feather from G. gallus (C and D). (A) Low-magnification image. (B) High-magnification image of the boxed area in A. (C) Low-magnification image. (D) High-magnification image of the boxed area in C. Both melanosomes and beta-keratin filaments are more densely distributed in the fossil sample. (Scales are as indicated.)‏ Yanhong Pan et al.
