Приводится детальное описание изолированных чешуй нового вида лучеперой рыбы Cheirolepis bychovensis sp. nov. из лепельских и адровских отложений Беларуси. По имеющимся в распоряжении автора данным установлено, что в породах лепельского возраста чешуи этого вида встречаются гораздо чаще, чем в породах адровского. Это может быть связано, например, с несколько худшей изученностью адровских отложений в палеоихтиологическом отношении. Дальнейшие исследования позволят это выяснить. Сохранность чешуй хорошая, что позволяет их детально изучить и описать. Помимо описательной палеонтологической части в статье указываются данные по сопутствующим органическим остаткам, обнаруженным совместно с чешуями этого представителя лучеперой рыбы, а также приводится литологическая характеристика вмещающих пород, в которых были обнаружены чешуи нового вида. Приведенные в статье данные дополняют информацию о таксономическом составе позднеэмсской и раннеэйфельской ихтиофауны в пределах республики. В качестве стратиграфической основы использована Стратиграфическая схема девонских отложений Беларуси 2010 г.

This paper presents a detailed description of some isolated scales of a new species of the ray-finned fish of Cheirolepis bychovensis sp. nov. found in the Lepel and Adrov deposits of Belarus. The data that the author has available suggest that the scales of this species are much more numerous in the rocks of the Lepel age, than in the Adrov rocks. This may be due to the fact that the Adrov deposits are so far poorly known in terms of their palaeoichthyology. Further investigations are needed to clarify this moment. The scales are well preserved, which allowed us to study and describe them in detail. In addition to the descriptive palaeontological part the paper presents the evidences of the associated organic remains found together with the scales of representatives of this ray-finned fish, and also provides a lithological characteristic of the enclosing rocks in which the scales of the new species were found. The data presented in the paper supplement the information on the taxonomic composition of the Late Emsian and Early Eifelian ichthyofauna within the country. The Stratigraphic Chart of the Devonian deposits of Belarus (2010) was used as a stratigraphic ground.
