†Titanonarke molini (Jaekel, 1894) from the Eocene Monte Postale site. A, B, UV images of the holotype MGP-PD 26275/6 showing that it was covered with a pigment reflecting an orange light (see also Supplementary material). The arrows in A indicate a leaf also covered with the pigment, a drop, and some rays that were not distally covered (they are blue/grey, as expected); the arrowhead in A indicates part of the third branch of the antorbital cartilage not covered by pigment; the arrowhead in B indicates the rostral appendix; C, Narcine brasiliensis (TNHC 18512); the arrows indicate the rostral appendices. Scale bars: A, B = 50 mm; C = 10 mm.
