Description
Summary:FIGURE 11. Architecture and articulations in Ptilocrinus brucei pinnules. A–B: genital pinnule inflation in specimen USNM 1005439; A: proximal part, B: distal part; C–D: specimen USNM 1005438; C: proximal part with multiplated adoral skeleton covering female gonad (g); D: detail of gonad showing submature oocytes; E–I: specimen USNM 1005439; E: proximal muscular synarthry of Pn2; F: aboral distal view of Pn2; G: proximal synostose of Pn3; H: pinnule broken proximally to Pn4 (cv: cover plates, Pn: pinnular, arrow indicating convex side of genital inflation); I: proximal synostose of asymetrical Pn4 (adoral plates removed, orientation like in H).
