Taxonomic list

• Pfefferkorn 1979 compiled a list of genera (all plant organs) to compare Mazon Creek diversity to 3 other localities of similar age. This is a very general list integrating all MC pits, so need to add more Mazon Creek collections that parse out the taxon occurrences by pit. Check with Pfefferkorn to see if he has such data. Also Noe's papers.
