The short review of the history of the Order Spiriferida system have been done. The leading directions of evolutions of the majorgroups of Carboniferous spiriferids of Eastern Europe were determined. The main changes in the content of SuperfamiliesMartinioidea and Spiriferoidea were substantiated by the author. The family Brachythyrididae containing the subfamiliesBrachythyridinae and Skelidorygminae was included in Superfamily Martinioidea. The Family Angiospiriferidae according to author’sopinion contains the Subfamilies Angiospiriferinae Legrand-Blain, Brachythyrininae Waterhouse, Choristitinae Waterhouse, andwere included in Superfamily Spiriferoidea. The new Superfamily Neospiriferoidea containing the families Imbrexiidae Carter,Neospiriferidae Waterhouse, Trigonotretidae Schuchert, Spiriferellidae Waterhouse was established. The evolution of morphologyspiriferids and manner to fix the shells to ground were associated with change of type of sediments in Carboniferous.
