Acta Palaeontologica Polonica 36 (4), 1991: 413-426

Specimens of 'Discotrochus' duncani, at various stages of transverse division occurabundantly in the Miocene Korytnica clays in the Holy Cross Mountains, Poland. This mode-of asexual reproduction probably predominated in the studied population, and is here put forward as an adaptation for rapid colonization of soft bottoms. Truncatocyathus gen. n. is proposed to include 'D.' duncani.

Key words: asexual reproduction, transverse division, Scleractinia, Tertiary.
