Co-Growth in Rugosa: Types, Morphology, Special Features and Origin

This paper presents the results of a study of rugose corals from the Ordovician and Silurian of Estonia and the Carboniferous of the Moscow region, and describes their taxonomy in detail. The sections from which the studied material was collected are also described. Morphogenetic characters of the genera and species studied are analyzed based on the available material. New methods of studying this fossil group are proposed. The issue of corallite mutual growth described on the studied material was determined, the main features of rugosan growth during joint settlement, regeneration and astogeny were identified
