Taxonomic list
• not clear if this includes 1940 Thomson specimens of Miniochoerus affinis (Schultz and Falkenbach 1956) and "Paramerycoidodon wanlessi" (Schultz and Falkenbach 1968) from "Little Bad Lands, Oelrichs"
because this is equivalent to Whitney A, I assume it also equals "Brule Zone C" of F:AM collections
