Taxonomic list

• MNA 704-1, OMNH V6, and UCM 83258 are the same
most specimens from OMNV V6 and V9; V9 is stratigraphically 20 m above V6; V14 is 60 m above V9
all localities also have MNA numbers
although 69 therian specimens are listed, at Burnham South and Jacobs Bone Bed these average only 3/14 of the fauna, so the number of multituberculates cannot be extrapolated reliably
