“…These trans‐Artic Plumularioidea colonizations were probably from the Atlantic to the Pacific (Figure ), which contradicts the prevalent eastward gene flow direction assumed for most marine taxa (e.g., Briggs & Bowen, ; Durham & MacNeil, ; Marincovich & Gladenkov, ; Vermeij, ; Vermeij, ) but agrees with inferred mollusk colonizations and predominant southward currents through the Bering Strait when it opened ca. 5.5–4.8 Mya (Marincovich, ; Marincovich, Barinov, & Oleinik, ). However, due to an underrepresentation of Plumularioidea samples from the temperate/cold waters of the NW Atlantic, we cannot exclude the hypothesis of postglacial recolonization of the NW Atlantic from the NW Pacific.…”

We provide preliminary insights into the global phylogeographic and evolutionary patterns across species of the hydrozoan superfamily Plumularioidea (Cnidaria: Hydrozoa). We analyzed 1,114 16S sequences of 198 putative species of Plumularioidea collected worldwide. We investigated genetic connections and divergence in relation to present‐day and ancient biogeographic barriers, climate changes and oceanic circulation. Geographical distributions of most species are generally more constrained than previously assumed. Some species able to raft are dispersed widely. Human‐mediated dispersal explains some wide geographical ranges. Trans‐Atlantic genetic connections are presently unlikely for most of the tropical‐temperate species, but were probably more frequent until the Miocene–Pliocene transition, before restriction of the Tethys Sea and the Central American Seaway. Trans‐Atlantic colonizations were predominantly directed westwards through (sub)tropical waters. The Azores were colonized multiple times and through different routes, mainly from the east Atlantic, at least since the Pliocene. Extant geminate clades separated by the Isthmus of Panama have predominantly Atlantic origin. Various ancient colonizations mainly directed from the Indian Ocean to the Atlantic occurred through the Tethys Sea and around South Africa in periods of lower intensity of the Benguela upwelling. Thermal tolerance, population sizes, dispersal strategies, oceanic currents, substrate preference, and land barriers are important factors for dispersal and speciation of marine hydroids.

“…Neptunea are predatory snails well represented in the earliest Miocene to Holocene of the northern Pacific and in the late Pliocene to Holocene of the Arctic and northern Atlantic. The presence of Neptunea gives a maximum age for these deposits of latest Miocene or early Pliocene, after the opening of the Bering Strait (Marincovich and Gladenkov 1999; Marincovich et al 2002). …”

Bivalve mollusk shells were collected in 2350 m depth in the Beaufort Sea, Arctic Ocean off northern Alaska. Initial identification suggested the specimens were a member of the bivalve family Thyasiridae, but no known eastern Pacific or Arctic living or fossil thyasirid resembled these deep-water specimens. Comparisons were made with the type of the genera Maorithyas Fleming, 1950, Spinaxinus Oliver & Holmes, 2006, Axinus Sowerby, 1821, and Parathyasira Iredale, 1930. We determined the Beaufort Sea species represents a new genus, herein described as Wallerconcha. These specimens also represent a new species, herein named Wallerconcha sarae. These new taxa are compared with known modern and fossil genera and species of thyasirds.
