Abstrakt CZ: Clusters of discinid brachiopod shells observed in the early Devonian and Carboniferous are interpreted as original life assemblages. These clusters consist of Gigadiscina lessardi (from Algeria), Oehlertella tarutensis (from Libya), Orbiculoidea bulla (from England), and O. nitida (from England). Grape-like clusters of the Recent species Discinisca lamellosa, D. sowerbyi and D. tenuis are described and their spacing and size-frequency distribution are discussed. The possible function of clustering as protection against grazing pressure is suggested.
