Note:

Echinoderm class Crinoidea contains over 6000 fossil species in over 800 genera and approximately 600 living species, of which 540 nominal species in 142 genera are comatulids (feather stars). There is still circa 60 species of stalked sea lilies, the last hang-overs from the Palaeozoicum. (Hess, Ausich, Brett & Simms, 1999, Messing, ????)
