The Mechetlino Quarry section is a potential candidate for the Global Section Stratotype and Point (GSSP) for the base of the Global Kungurian Stage on the International Stratigraphic Chart. In 2017, the Mechetlino Quarry section became the part of the First Geopark in Russia, therefore excavation work was carried out to clear it, a road was laid, and infrastructure was developed. Recent evidence to justify the base Kungurian boundary in the Mechetlino section was obtained. Additional conodonts confirmed the data of V.V. Chernykh on the Artinskian–Kungurian transition. Besides Neostreptognathodus pnevi Kozur and Movshovitsch, the second marker (N. lectulus Chernykh) of the base-Kungurian was established. The Artinskian–Kungurian transition of the Mechetlino Quarry section is characterized by the richest associations of small foraminifers, ammonoids, and other groups. The occurrence of mass Clausiuraloceras above the Kungurian boundary, which changed the representative Artinskian association, was identified. Small foraminifers of the Artinskian–Kungurian transition are numerous and include sufficient species to provide a correlation with Western Tethys, Svalbard and Australia. Data on isotopic ratios of δ¹³C and δ¹⁸O, δ¹³C_org values and the magnetic susceptibility were obtained for the first time.

Mechetlino采石场部分可能是国际地层图上全球昆古里阶的基础的全球断层地层和点（GSSP）的潜在候选者。2017年，Mechetlino采石场部分成为俄罗斯第一地质公园的一部分，因此进行了挖掘工作以进行清理，铺设了道路并开发了基础设施。最近的证据证明了Mechetlino断面的基本昆古里边界是合理的。其他牙形体证实了VV Chernykh有关Artinskian-Kungurian过渡的数据。此外Neostreptognathodus pnevi Kozur和Movshovitsch，第二标记（N. lectulus建立了基础库古里亚人的Chernykh）。Mechetlino采石场区域的Artinskian-Kungurian过渡特征是有孔虫，氨类动物和其他群体的最丰富的联系。确定了在昆古里亚边界上方发生的大规模克劳德龙角藻的发生，从而改变了代表性的阿丁斯基公会。Artinskian-Kungurian过渡的小型有孔虫数量众多，并且包括足以与西特提斯，斯瓦尔巴特群岛和澳大利亚相关的物种。上的δ同位素比率数据¹³ C和δ ¹⁸ O，δ ¹³ Ç_有机被首次获得的值和磁化率。
