• outcrop-level geographic resolution
When: Viviparus other zone, Pliocene (5.3 - 2.6 Ma)
• This publication introduces the new Cernikian regional stage, which corresponds to the Viviparus (=Paludina) beds, and is broadly congruent to the Pliocene and lower Pleistocene (4.5 m.y.a. to 2 m.y.a.).
•"The outcrop area is an active landslide laterally extending about 50 m. Except for a 3.4 m thick interval exposed at the northern limit of the landslide area, the bedding is largely disturbed. The former outcrop is dominated by a structure-less, grayish to yellowish clayey silt, with scattered plant remains. A 1.15 m thick unit of gray homogenous clay is intercalated in the lower part of the interval. The topmost 25% of this package displays fine-scale banding due to the intercalation of fine and medium grained sand. The sampled mollusc concentration occurs in the land-slide area, laterally to the outcrop, being strongly deformed and disjointed. It acted apparently as an inhomogeneity surface with the original stratigraphic position on top of the undisturbed interval."
