Taxonomic list
• thought by Hibbard to underlie the Hagerman "formation" but actually "more than 600 feet" above the Gidley Horse Quarry: Malde 1972; Zakrzewski 1969 gives a figure of 900' above localities at about the latter level, but 600' is used as an estimate because Malde's figured section and discussion are unequivocal
