Extended Data Fig. 2. Distribution of feather types in the tapejarid pterosaur Tupandactylus cf. imperator (MCT.R.1884).

a, Schematic illustration of MCT.R.1884. Monofilaments (red) are restricted to the region immediately adjacent to the proximal part of the occipital process and the branched feathers (blue) to the region adjacent to the distal part of the occipital process. The cranial soft tissue crest is shown in dark grey and the preserved bones are shown in white. The proximal part of the skull (in black) is not present on the slab. b, Reconstruction of MCT.R.1884 showing the distribution of feathers along the occipital process (colours are not reconstructed here).
