''Gogia'' is a primitive genus of eocrinoid blastozoan from the early to middle Cambrian. ''G. ojenai'' dates to the late Early Cambrian;〔 other species come from various Middle Cambrian strata throughout North America, but the genus has yet to be described outside this continent. The species of ''Gogia'', like other eocrinoids, were not closely related to the true crinoids, instead, being more closely related to the blastoids. ''Gogia'' is distinguished from sea lilies, and most other blastoids, in that the plate-covered body was shaped like a vase, or a bowling pin (with the pin part stuck into the substrate), and that the five ambulacra were split into pairs of coiled or straight, ribbon-like strands. As a whole, the Eocrinoids are regarded as basal blastozoans very close to the ancestry of the entire subphylum. ==External links== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gogia」の詳細全文を読む スポンサード リンク
