correlation event | Imprecise. Between the Base of acritarch biozone 5 and LAD of conodont Pterospathodus amorphognathoides. The current Stratotype Point does not coincide with the Base of the Cyrtograptus centrifugus Biozone, as was supposed when the Stratotype Point was defined. Restudy recommends a slightly higher and correlatable level on condonts the Ireviken datum 2, which coincides approximately with the Base of the murchisoni Graptolite Biozone | |||||||
