Extended Data Figure 9 in A bizarre Jurassic maniraptoran theropod with preserved evidence of membranous wings

Extended Data Figure 9 | Scanning electron microscopy images of melanosomes and melanosome impressions preserved in Yi qi holotype (STM 31-2). a–m, Note the high morphological diversity of the preserved melanosomes in the feathers, which include: densely distributed, small round phaeomelanosomes and sparsely distributed, medium-sized oval eumelanosomes in the feathers near the skull (a); medium-sized elongate elliptical eumelanosomes in the feathers near the skull (b, c), neck (d, e), humerus (f, g), and ulna (h, i, j); and large oval and elliptical eumelanosomes in the feathers near the tibiotarsus (k, l). The subspherical phaeomelanosomes in the sheet-like soft tissue (m) appear to be less densely distributed than the melanosomes in the feathers.
