Aggregated character of the colony in Catenipora and Halysites

The proper colony form of Catenipora and Halysites is a single chain, which never branched, budding in these corals being terminal and singular. The buds never appeared on lateral walls nor on the junctions between the neighbouring corallites. The chains, singular at first, later on joined together accidentally, forming an aggregate colony, which was built by several generations of planulae. The corallite structure and offsetting are typical of Tabulata.
Key words: Tabulata, astogeny, systematics, Silurian.
