High levels of endemism and complex, overlapping biogeographic patterns characterize modern molluscan faunas of the Hawaiian Islands and the Triassic bivalve fauna of the Wallowa volcanic-arc terrane in Hells Canyon, Oregon. Such biogeographic complexities and high levels of endemism in many modern and Mesozoic island settings constrain the use of faunal data as a primary basis for paleogeographic reconstruction of accreted terranes. Large, taxonomically diver samples are required to identify genuine biogeographic patterns in these insular settings. Selective use of individual species, genera, or families to reconstruct terrane paleogeography may give misleading results.
