A. A. Borisyak suggested that I study the Liassic fauna he and his colleagues had collected in the vicinity of Yalta and the village of Bodrak in Crimea. In the vicinity of Yalta, this fauna was noticed in the fencing of an estate. Careful searches eventually led to a small abandoned quarry, where a block of limestone containing the said fauna was found among shales. It was not possible to determine the relationship between the limestones and shales on site. The research provided undeniable paleontological evidence that part of the Crimean shale strata belongs to the Lias, and the villages of Bodrak and the vicinity of Yalta yielded the most abundant Liassic fauna.
