Taxonomic list

• COVERAGE: Limited to taxa mentioned in text; based on reinterpretation of Dall (1890-1903). NOMENCLATURE: Not an authoritative publication, and with somewhat antiquated nomenclature, but with species-resolution identifications. NOTE: Austin seems to have duplicated Martin's Station, which is the same formation and documented in the same works as Richard's Quarry. So, I subverted it (PJW 2016-02-07).
