Material and occurrence.Many specimens, three illustrated (GZG.INV.84973-75) from Bear Creek (Valanginian, Early Cretaceous).
Remarks. R.? tuberculatawas known so far from the Rice Valley and Wilbur Springs localities (Campbell et al.2008), both Hauterivian in age (see localities #3 and # 5 in Kiel et al, 2008b). Here we report abundant occurrence of this species from Bear Creek locality that is probably Valanginian.
