FIGURE 5. Holotype of Feracrinus heinzelleri n. sp. (ZSM 0000/1), pinnule ossicles. A–C: views of the two proximalmost pinnulars (p1 and p2); A: proximal adoral view showing facet of muscular transverse synarthry; B: adoral view, proximal transverse synarthry at right, distal synostosis at left, p1 articulated to p2 by muscular synarthry (see D); C: distal adoral view showing flat synostosial facet; D: proximal synarthry of p2; E: pinnular in mid pinnule with synostosial facets; F: distal pinnular with muscular articulations; G–I: H-shaped genital plate; G: front view; H: lateral external view, ambulacral side at top; I: lateral internal view; J: profile view of genital, H-shaped and covering plates on genital pinnule; K: detailed view of covering plates; L-M: dissociated proximal cover plate. adp: additional lateral plates; cp: cover plates; gp: genital H-shaped plates; p: pinnular.Published as part of Eléaume, Marc, Bohn, Jens-Michael, Roux, Michel & Améziane, Nadia, 2012, Stalked crinoids (Echinodermata) collected by the R / V Polarstern and Meteor in the south Atlantic and in Antarctica, pp. 1-22 in Zootaxa 3425 on page 10, DOI: 10.5281/zenodo.20941
