• Until now, we have no any evidence suggesting the Bolorian conclusively, such as Brevaxina and Misellina, for the age of SNF34. Combining all these lines of available information, however, this sample is probably slightly younger than Yakhtashian, and a Bolorian age seems to be more advisable judging mainly from the occurrences of Pseudofusulina dzamantalensis, Darvasites minatoi, and Kubergandella? sp
