FIGURE 12 in A revision of the genus Conocrinus d'Orbigny, 1850 (Echinodermata, Crinoidea, Rhizocrinidae) and its place among extant and fossil crinoids with a xenomorphic stalk

FIGURE 12. Constraints to phylogenetic reconstruction and classification of post-Paleozoic crinoids with a xenomorphic stalk (except Caledonicrinus): second hypothesis. In this hypothesis, B. ellipticus (B.e) and B. fisheri (B.fish) are considered congeneric, Bourgueticrinidae (including Naumachocrinus) remaining within Bourgueticrinina, and Dunnicrinus lineage with B. suedicus (?B.s) + B. ex gr. fisheri of Zitt & Vodrazka (2008) (?B.cf) corresponding to a new family (N.F.?) distant to Bourgueticrinina. For other abbreviations, see Fig. 11.
