close to the top of a normal magnetic polarity zone interpreted as C28n, but there is no tie point in the section: see Lucas et al. 1997 firmly correlated with Wagonroad Upper Horizon, which was included in the list of Tomida and Butler 1980; paleomagnetic data strongly support a correlation between the two horizons
descriptions of Robison 1986 do not incorporate the collections reported by Tomida and Butler and Tomida 1982
"Oxyclaenus pearcei" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon

Haploconus "inopinatus" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon
