Hi Jerermy, Bralower et al. 1989 does not give a Late Valanginian age for R, wisei he place the top of R. wisei at the top of E calpionellid zone which is top Early Valanginian and between M13 and M12N polarity chron which is intra Early Valanginian in age in Gradstein 2012. I think the range should match the Neptune datebase in the Valanginian to Berriasian interval.
