Retiskenea   ? tuberculata Campbell et al., 2008

( Fig. 5 A –D View FIGURE 5. A – D )

Material and occurrence. Many specimens, three illustrated (GZG.INV. 84973 - 75) from Bear Creek (Valanginian, Early Cretaceous).

Remarks. R.? tuberculata was 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, 2008 b). Here we report abundant occurrence of this species from Bear Creek locality that is probably Valanginian.
