“…An additional explanation for thermally anom alous faunas on the Channel Islands is that the fossils date to a single interglacial period but that the assemblage as a whole represents a long period within that interglacial, including a period of peak warmth and a later period when cooling had begun but sea level had not yet fallen. This explanation was offered for the mix of extralimital-southern "Senegalese" species and extralimital-northern Mediterranean species coexisting in marine deposits dated to MIS 5.5 (~120 ka) on the Canary Islands (Muhs et al 2014c). In this orbitally forced scenario for the eastern Atlantic Ocean, higher insolation early in the LIG period brought about not only direct warming but also a northward migration of the intertropical convergence zone, decreased trade winds, and decreased upwelling.…”

“…For the study areas considered here, these would be species that now live well to the north or south of Santa Barbara Island (SBI) and Anacapa Island (ANA). Extralimital species of mollusks and corals, indicating warmer SST during MIS 5.5, have been documented in the Indian Ocean along the western coast of Australia (Kendrick et al 1991), around New Zealand and the southern coast of Australia (Murray-Wallace et al 2000), along the Bering Sea and Arctic Ocean coasts of Alaska (Brigham-Grette and Hopkins 1995), in the eastern Atlantic Ocean and Mediterranean (Meco et al 2002, Muhs et al 2014c, in the Pacific Ocean along the shores of Oahu in the Hawaiian Islands (Kosuge 1969, Muhs et al 2002b), along the central and southern California coast (Kennedy 2000, Muhs et al 2002a, 2014a, 2014b, and in Baja California (Lindberg et al 1980, Emerson et al 1981. Thus, the importance of thermal expansion during the LIG may have been greater than the studies of Turney and Jones (2010) and McKay et al (2011) imply.…”

Marine terraces are common on the Pacific Coast of North America and record interglacial high-sea stands superimposed on either stable or tectonically rising crustal blocks. Despite many years of study of these landforms in southern California, little work on terraces has been conducted on the two smallest of the California Channel Islands, Santa Barbara Island (SBI) and Anacapa Island (ANA). Presented here are new field and laboratory data on the ages, paleontology, and sea level history of marine terraces of these two islands. On both islands, the lowest marine terraces have shoreline angle elevations of ~11 m above sea level. Amino acid geochronology shows that terrace deposits on both islands host fossils of two ages, one group dating to the ~120-ka high-sea stand and the other group likely dating to the ~100-ka high-sea stand. A mix of fossil ages is consistent with the paleontology as well, with SBI in particular showing a faunal assemblage that includes both extralimital southern and southward-ranging species (inferred to be from the ~120-ka high-sea stand) and extralimital northern and northward-ranging species (inferred to be from thẽ 100-ka high-sea stand). Fossil mixing from these two high-sea stands supports the hypothesis that glacial isostatic adjustment (GIA) processes have left a strong imprint on the geologic record of sea level history in southern California. Nevertheless, the elevations of these terraces and that of a low terrace on Santa Cruz Island indicate that modeled GIA estimates of paleo-sea level for the peak of the last interglacial period at ~120 ka could be too high. Future development of models of GIA effects on the Pacific Coast of North America will need to consider geologic records, such as those from SBI and ANA, in refining reconstructions of sea level history.

Two new 40 Ar/ 39 Ar ages (*) and previously published K/Ar ages of basaltic pillow lava flows are coeval with closely-related fossiliferous marine layers, allowing us to establish the beginning (5.8; 5.0; 4.8 Ma at Ajuí, Fuerteventura Island and 4.8 ± 0.03 Ma (2)* at Tamaraceite) and a middle stage (4.20 ± 0.18 Ma (2)* at La Esfinge in Gran Canaria Island) of Early Pliocene marine deposits in the Canary A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 2 Islands. Here the presence of tropicopolitan fossils (Megaselachus megalodon, Janthina typica) suggest the influence of a possible Central American Circumtropical Current during the Pliocene and in the North Atlantic basin. The presence of both Janthina typica and the Argonauta argo also indicate the occurrence of tropical storms in the area of the Canary Islands around that time. In addition, the pillow lava flow at La Esfinge overlies a submarine pyroclastic layer containing Ostrea offreti that was preserved in its life position, a fossil from the terminal Miocene and commonly found on the south eastern Iberian Peninsula. At La Cruz on Fuerteventura Island, a dune formed above marine deposits lies beneath a palaeosol and a basaltic lava flow that is was K/Ar dated at 2.9 Ma. Near El Mármol in Gran Canaria the corresponding palaeosol lies between lava flows K/Ar dated at 3 Ma. Based on these observations, we argue in this paper that the first appearance of the Canary Current, the eastern boundary current of the North Atlantic sub-tropical gyre, occurred between 4.2Ma and 2.9 Ma ago. This was followed by a major sea level drop (of about 40 m) and the formation of a first fossil-bearing palaeosol which indicate that major climate change that took place around 2.95-2.82 Ma.

This study is based on the anal y sis of the sedimentology and the fos sil as sem blages of Pleis to cene de pos its in East ern Tu nisia. It uses dif fer ent fauna as sem blages to help in fer palaeoenvironments and in par tic u lar dis cusses the im por tance of the dis tri bu tion of Persististrombus latus, es pe cially as re gards MIS 5e de pos its around the Med i ter ra nean Ba sin. The stratigraphic suc ces sion has been di vided into two main units. The lower unit is quartz-rich. Its basal part con tains a ma rine fauna that in cludes well-pre served bi valves, gas tro pods, echinoids and cirripedes dom i nated by Acanthocardia, Cerastoderma, Parvicardium, Arca, Donax, Glycymeris, Loripes, Tellina and Cerithium.

The up per unit is car bon ate-dom i nated. Its basal part also con tains a rich ma rine fauna that in cludes the ex tant trop i cal West Af ri can spe cies Persististrombus latus.
