Stratigraphy
| Formation: | Kul'bich | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Unfortunately, the localities are not designated as either terrigenous or calcareous terrigenous ""types"". Only vague lithologies can be inferred and ""types"" inferred through the biozone descriptions. If the lithology is the terrigenous type, the formation is Tandoshinskaya, if the lithology is calcareous-terrigenous type, the formation is either Yelandin or Bol'sheishin. PJW: reticulatus zone here now is the Kul'bich formation. | |||||
