Typically, cladocerans have been used in these endeavors [15,19,20,26,27,28], and large branchiopods have only recently been used in these studies [21,22,25]. This is in part due to large branchiopods being primarily found in seasonally astatic aquatic habitats, while most recent paleolimnological studies have utilized large lake sediment cores.In this study, we examine, identify, and discuss fossil remains of large branchiopod crustaceans collected from six sites across the Beringian region (north-eastern Asia and north-western North America). Eggs and mandibles from Anostraca andIn Mexico, and Arizona, as in many parts of the world, multispecies assemblages of large branchiopods are a common phenomenon.
