... except that there are no L:R rhombs (Bockelie’s system 3) since caryocrinitids lack radial plates. Currently, three families are recognized within the Hemicosmitoida, the Hemicosmitidae, Caryocrinitidae and Thomacystidae (see Paul, 1984 , fig. 57, p. 84). The last is based on the unique genus...

Finally, Sprinkle ( 1973 , p. 43, fig. 16...

... missouriensis Rowley, 1900 , (Hemicosmitidae, Silurian, Fig. 20 .7, 20 .8) is a pavement of fewer than ten solidly sutured plates forming a tegmen (Sumrall and Waters, 2012 , p. 965). It is possible that the five to seven of the largest plates could be modified PPCP; however, homology of plates is unclear...
