Geology notes

generally good preservation of echinoderms noted; holdfasts; biostromes and thickets; localized winnowed units; trilobites and bryozoans fragmented; "This is one of the few Midwest Silurian echinoderm associations which occur in both carbonate and argillaceous carbonate dominated facies. The community appears to have been subject to wave or current action periodically, but not continuously, i.e. was subject to effects from more than just very major storms...most likely BA 4 to outer BA 3."\r\nSEP environmental call based on given information and knowledge of regional geology
