New representatives of Clathrodictyidae Kuhn from the Silurian of Tuva
- Authors:
- O. V. Bogoyavlenskaya
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.

Issues of paleobiogeography and stratigraphy of the Silurian of Tuva in connection with new data on brachiopods of the Chergak series
By the early 1980s, a monographic description of the main groups of organic remains from the Chergak series of Tuva had been largely completed and published: stromatoporates, tabulates, rugosas, bryozoans, crinoids.

Definitive list of Devonian colonial rugosas of the USSR (code species key)
- Authors:
- N. Ya. Spassky
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.

Definitive list of Devonian solitary rugosa of the USSR (coded species key)
- Authors:
- A. G. Kravtsov
The coding of morphological characters of the rugose skeleton as a basis for the subsequent determination of the taxon from suborder to genus inclusive was first proposed in the article by N.Ya, Spassky in 1971. Subsequent experience of application showed the high efficiency of this methodology, significantly reducing the time of training, specialists and the very definition of species.

Rugoses from the Kamenka Bay horizon of the southern part of Novaya Zemlya
- Authors:
- G. V. Lakhov
The Kamenka Bay horizon is the lowest regional stratigraphic unit of the Devonian on Novaya Zemlya. Within the southern part of the archipelago (Vaigach-Yuzhno-Novaya Zemlya structural-facial zone) it includes a thick (700-1000 m) stratum of terrigenous-carbonate formations, which is divided into three formations (from bottom to top): the Propaschinskian, West Nogorskian and Karandean.

New Devonian spiriferids of Transcaucasia
- Authors:
- I. A. Grechishnikova
Spiriferidae occupy a prominent place in the brachiopod complexes of Devonian sediments of Transcaucasia. Biostratigraphic studies undertaken by the author in the 1980s, allowed to clarify their composition and establish new species and subspecies.

Some Devonian trilobites of Transcaucasia
- Authors:
- E. S. Levitsky
It is known that the Devonian of Transcaucasia, represented by the Upper Ems and all stages of the middle and upper sections, is characterized by a variety of trilobites. The latter form a complex of at least 35 forms, most of which are new species.
