TABLE 1. Table of the characteristics of the different pycnofibre types.

Pycnofibre type	Occurrence	General characteristics	Abundance and special features	Examples of Figures
1st type: Simple-shaped impressions	-dorsal to the dorsal vertebral column -ventral to the zeugopodia of the right wing -ventral to the cervical vertebral column	-elongated, curved and largely unbranched -commonly intersections or overlaps -high variability of curvature and orientation depending on the body region	-high; the predominant type -insertion from a striking indent at the dorsal vertebral column -mane-like appearance dorsal to the dorsal vertebral column	Figure 4A, 4C, Figure 5A, 5B, Figure 7C, Figure 8C, Figure 9B
2nd type: bifurcations	-anterior part of the dorsal vertebral column -ventral to the zeugopodia of the right wing near the metacarpo- phalangeal joint	-two side branches branching off from a longer main branch -very characteristic Y -shape	-at least two occurrences, maybe even a third one on the counter slab	Figure 5A, 5B, Figure 6G, Figure 8C, 8E
3rd type: trident	-ventral to the zeugopodial bones of the right wing -ventral to the cervical vertebral column?	-terminal bifurcation consisting of three different side branches -side branches -more or less of equal length	-rare, one certain occurrence and one potential	Figure 6A, 6C, 6D, 6F, Figure 9B
4th type: main branch with caudally bent side branches	-ventral to the zeugopodia of the right wing	-at least one side with several side branches bent caudally -slightly different length of the side branches	-unique occurrence -unusual symmetry with the side branches only at one side of the main branch	Figure 6D, 6F
5th type: tuft	-ventral to the zeugopodia of the right wing	-several side branches spreading out in a radiating pattern from a common starting point -decreasing length, but increasing curvature of the side branches towards the margin -middle side branch with a smaller bifurcation	-unique occurrence -possibly belonging to a much larger structure or even linked with the symmetrical feather (main branch of the feather)	Figure 6C, 6D, 6H, Figure 7A
6th type: symmetrical feather	-ventral to the zeugopodia of the right wing at the articulation of the first with the second phalanx of the right wing finger	-two distinct parts: a terminal ramification consisting of several side branches and a main branch -variable length of the side branches with the length and curvature decreasing towards the centre of the ramification	-unique occurrence	Figure 7D, 7E, 7G, 7H
