- Figure 26. Posterior slope of right valve of Hedecardium (Hedecardium) waitakiense (DSIRGS 10837). A, dorsalmost region of posterior slope. Arrow on right of figure indicates change in ribbing pattern between central slope and posterior slope. Arrow on left of figure indicates small simple spines on top of radial ribs. Scale bar = 5 mm. B, same specimen as in A, view more toward ventral margin; posterior margin visible at left of figure. Larger arrow indicates change in ribbing pattern between central and posterior slopes. Smaller arrow indicates small spine on top of rib. This rib and the next two posteriormost ribs display the eucardiid feature of a primary radial thread (see Schneider, 1998a). Scale bar = 7 mm.
