The Ordovician and Silurian stromatoporates of Tuva are known thanks to the studies of V. N. Ryabinin, V. I. Yavorsky, and O. V. Bogoyavlenskaya. In the process of monographic study of stromatoporites, a significant distribution of representatives of the family Clathrodictyidae was established, many of which can be of considerable help in interregional correlations.
