Definitive list of Devonian colonial rugosas of the USSR (code species key)
Authors:
Abstract
The coding of morphological features of skeletal elements of rugosas as a basis for determinants was first applied by N. J. Spassky in 1971. Unlike the generic code key, in which qualitative differences were recorded, the proposed species key also includes quantitative parameters characterizing the morphology of the skeleton of corallites.
