註釋"Fistuliporacean bryozoans occur sparingly in the Wreford Megacyclothm (Lower Permian) in Kansas, in a distribution which indicates that they were restricted paleo-environmentally to quiet, offshore, normal-marine waters with a mixed clay-line-mud bottom. Utilization of population-size samples, standardized numerical parameters, and paleobiologic species concepts indicates that the Wreford fistuliporaceans comprise three highly variable species--Fisulipora incrustans, F. carbonaria, and Meekopora prosseri. Their morphology and variability, in addition to thoroughly characterizing their distinctive features, suggest some general skeletal-growth patterns and some doubts regarding the taxonomic usefulness of certain features such as the degree of lunarial development and indentation of the intrazooecial cavity."--Pg. [1].
