Taxonomic list
• "Otionohyus bullatus" Schultz and Falkenbach 1968: YPM "Eporeodon helenae" specimen of Thorpe 1937 said to be from the non-existent "Crow Buttes, South Dakota"; same specimen (!) referred to "Paramerycoidodon major" by the authors on another page, but this appears to be an error; level unclear as "O. bullatus" is Brule Zone B whereas "P. major" is Brule Zone D
