Taxonomic list

• records of Williamson and Lucas 1993 could include some material from Betonnie-Tsosie Arroyo
identical to list 13 of Williamson 1996
entire section is of reversed polarity according to Taylor 1981
type of Ellipsodon "yotankae" appears to be from Sinclair and Granger Locality 8; see Van Valen 1978
partial list of Taylor 1981 is repeated from Wilson almost without modification but includes Triisodon; this might be a lapsus as the KUVP 13 record of Triisodon appears in an adjacent column of Wilson's table
paleomag correlation is based on entirely reversed polarity of local section, but there is no tie point and the correlation is completely ambiguous
