Abstract

The presence of the cystoids Codiocystis and Phiyctocystis in the Llandeilo of Spain, associated to an undetermined Diploporite which may be a new genus, in confirmed. Several species of the genus Calix are described, some of them in open nomenclature, certain forms bearing a pentaradiated peristome. New samples of Homalozoa collected in the Middle Cambrian of Sierra Morena (Decacystis) and the Lower Llanvirn of the Toledo Mountains (Mitrocystites) are quotated, as well as an Asterozoa (Polaeura), found for the first time in Spain. The study of the echinoderm fauna collected in the "Tristani beds" (Llanvirn-Llandeilo) of the Spanish Central-iberian zone allow to establish conclusions of biostratigraphic and paleobiogeographic interest.
