Stratigraphy
Formation:Valnev Horizon
Stratigraphic resolution:formation
Stratigraphy comments: Lower part of Valnev Horizon corresponds to the Nordotoechia tumida/Taimyrrhynx polaris Lona. "A Lona is a regional taxonomic unit, subordinate to a horizon and corresponding to a minor phase in the development of the basin and in the evolution of the organic world."
