These six collections come from rocks of Kayak? Shale lithology. Five have similar assemblages in yello-brown weathering crinoidal limestone. The fossils are all consistent with an early Mississippian (Osage) age and may be equivalent to the lower part of the Wachsmuth Limestone. One collection (BE 264) is in a different rock type and has fossils that are probably of Meramec age. This is probably equivalent to some part of the upper Wachsmuth Limestone. The material is being retained.
