Development and functional morphology of sutural pores in Early and Middle Cambrian gogiid eocrinoids from Guizhou Province, China

ABSTRACT

Trochocystites Barrande, 1887 (Homostelea) and Ceratocystis Jaekel, 1901 (Stylophora); but, they are especially common and diverse in gogiids (Eocrinoidea). All sutural pores are probably not the same, they may have evolved several times, but those in the Blastozoa and “Homalozoa” which apparently serve only a respiratory function are probably homologous.
