Collection methods and comments
Reason for describing collection: | biostratigraphic analysis |
Collection method comments: Collection only includes brachiopods and bivalves, but text says brachiopods are "most abundant...with bivalves as a minor constituent of the total fauna" and formation is generally "sparsely fossiliferous" |
