Seven samples were submitted, but I can only offer help on two of them. Samples 34B-2 and 39B definitely are Permian, with the typical Arctic fauna that has been dated as mid Permian, latest Leonard or early Guadalupe (Word) in terminology of the southwestern U.S. Unfortunately, the others contain only fenestellid bryozoans and such indeterminata as crinoid columnals and possible plant fragments. Our Upper Paleozoic bryozoalogist is incapacitated at present, so I connot promise identifications of the fenestellids. We would like to retain Sample 39B in the permanent reference set (assigned USGS No. 23889-PC) and a cut of the rest of the collection for the bryozoans. The excess will be discarded after about a year, unless you want them returned. If all samples are from the supposedly Mississippian Strelna Formation, at least we can now say that some Permian is involved. The samples have three lithologies: a coarse grained limestone with some definitely Permian brachiopods, a greenish, cherty, fine grained limestone with fenestellids, and a gray fine grained limestone (36A-1) with fenestellids.
