В опорном разрезе нижнего мела в окрестностях села Верхоречье (Бахчисарайский район, Республика Крым) сделаны находки редких аммонитов: верхневаланжинского Himantoceras lessinianum Faraoni et al. и валанжин-нижнеготеривского Olcostephanus densicostatus (Wegner). Эти находки уточняют сведения о  таксономии, географическом распространении аммонитов и  подтверждают существование тесной связи крымского палеобассейна с палеобассейнами Западного Средиземноморья. 

In the Lower Cretaceous reference section in the vicinity of the village of Verkhorechye (Bakhchisaray district, Republic of Crimea), rare ammonites were found: upper Valanginian Himantoceras lessinianum Faraoni et al. and Valanginian-lower Hauterivian Olcostephanus densicostatus (Wegner). These findings clarify information about the taxonomy and geographic distribution of ammonites and confirm the existence of a close connection between the Crimean paleobasin and the Western Mediterranean paleobasins.
