| Taxonomic list comments: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figured section and discussion are unequivocal from a normally magnetized ash: Thewissen and Smith 1987 UO 2045 (unpublished locality) is also at Sand Point: Shotwell 1970; referred to as UO "1045" by Neville et al. 1979 | |
