Abstract

Five bivalve species (Arcomytilus sanctaecrucis, Neithea valangiensis, Plagiostoma dubisiensis, Prohinnites renevieri, and Protocardia broili sp. nov.) are described from a new locality in Southwestern Crimea. These species, along with the gastropod Phaneroptyxis broili and the foraminifer Bramkampella arabica, indicate the Early Berriasian age of the carbonate deposits examined. The transition zone between the Upper Tithonian and the Lower Berriasian was identified in one of the sections.

Ai-Petri Yaila（西南克里米亚）北坡下贝里亚斯沉积物中的双壳类软体动物

摘要

从西南克里米亚的一个新地方描述了五种双壳类（Arcomytilus sanctaecrucis，Neithea valangiensis，Diagiosioma dubisiensis，Prohinnites renevieri和protocardia broili sp.nov。）。这些种类，与腹足纲的Phaneroptyxis broili和有孔虫Bramkampella arabica一起，表明了所研究的碳酸盐沉积物的早期贝里亚斯时代。上一节中确定了上提通统和下贝里亚统之间的过渡带。
