- Аннотация: The boundary interval in Trench B in the Verkhnyaya Kardailovka section contains the first evolutionary appearance of L. ziegleri in the L. nodosa - L. ziegleri lineage. Conodonts are found in association with many other fossil groups including foraminifers, ammonoids, holothurian ossicles, phyllocarid fragments and corals, which provides high correlation potential with both deep-water and shallow-water successions world-wide. The microfacies suggest essentially continuous deep-water deposition with little reworking or redeposition. The entire section and the boundary interval in particular, have been thoroughly sampled and marked with aluminium pins at one-metre intervals, allowing the precise documentation of sample levels.
