Abstract

Protorthacean brachiopods from the Middle Cambrian of the Moroccan Atlas regions are described in terms of morphology and systematic affinities. The superfamily Protorthacea is revised to include both Protorthidae and Bohemiellidae. Newly introduced is the protorthid genus Saesorthis, the morphologic characteristics as well as the significance of which are discussed in detail together with their bearing on early phylogeny of the Orthacea. A reinvestigation of Brahimorthis antiqua led to the recognition of additional morphologic peculiarities and enhances understanding of its stratigraphic occurrence. Additional descriptions and discussions deal with informally described protorthid and bohemiellid species. Bohemiella and Jamesella are reported from Africa for the first time.
