• coordinate based on political unit

• local area-level geographic resolution

Collection methods: Much overlap with collection 12936, but not strictly speaking a subset (for example, trilobites are listed here but not in that collection). Authors say this community is a subset of the Striispirifer-Amphistrophia Community, which is represented by collection 12936. I have included taxa from table 45.50 (listed there with abundances) as well as a few other taxa mentioned in text but not listed for the one locality in table.
