...ADOLF SEILACHER; ROLF B. HAUFF Abstract While all modern crinoids are benthic filter feeders, some fossil species found in low-oxygen Konservat-Lagerstätten probably were pelagic. Pseudoplanktonic forms were mostly attached to driftwood ( Seirocrinus , Traumatocrinus , Melocrinus ); they had long...

FIGURE 4 —Supposed tow-net crinoids used various morphogenetic modes to enlarge their permanently open filter fans. In Traumatocrinus , now found attached to driftwood, arms branched endotomously like Seirocrinus (see Fig. 3 ); but the ramuli returned to alternating heterotomous branching

... are not reported in any other fossil or modern crinoids. Other stalked crinoids, such as Traumatocrinus , have perforations (or tubulis) in the stalk, and these are greater in diameter than the spaces for ligamentary passages (e.g., Hess 2011 , fig. 19b). However, the diameters of tubuli are larger...
