“…It is suggested that the incipient growth of the Pacific plate drove increases in subduction rates attended by volcanic pulses and arc collisions, which were especially important during the Kimmeridgian (Bartolini and Larson, 2001;Kalnins and Watts, 2009). This circum-Panthalassan activity is well illustrated along the western coasts of USA, Canada, and Mexico (DeBari et al, 1999;Clift et al, 2005;Barboza-Gudiño et al, 2008), Andes and Patagonia (Féraud et al, 1999;Boekhout et al, 2012), New Zealand (Briggs et al, 2004), Northeast and Far East Russia (Sey et al, 1992), and Japan (Isozaki et al, 2010), where thick ash or volcaniclastic sequences, as well as magmatic effusions are recorded on terranes and continental margins.…”

Nd isotope constraints on ocean circulation, paleoclimate, and continental drainage during the Jurassic breakup of Pangea

The breakup of Pangea and onset of growth of the Pacific plate led to several paleoenvironmental feedbacks, which radically affected paleoclimate and ocean chemistry during the Jurassic. Overall, this period was characterized by intense volcanic degassing from large igneous provinces and circum-Panthalassan arcs, new oceanic circulation patterns, and changes in heat and humidity transports affecting continental weathering. Few studies, however, have attempted to unravel the global interactions linking these processes over the long-term. In this paper, we address this question by documenting the global changes in continental drainage and surface oceanic circulation for the whole Jurassic period. For this purpose, we present 53 new neodymium isotope values (ε Nd(t)) measured on well-dated fossil fish teeth, ichthyosaur bones, phosphatized nodules, phosphatized ooids, and clastic sediments from Europe, western Russia, and North America. Combined with an extensive compilation of published ε Nd(t) data, our results show that the continental sources of Nd were very heterogeneous across the world. Volcanic inputs from a Jurassic equivalent of the modern Pacific Ring of Fire contributed to radiogenic ε Nd(t) values (− 4 ε-units) in the Panthalassa Ocean. For the Tethyan Ocean, the average surface seawater signal was less radiogenic in the equatorial region (− 6.3), and gradually lower toward the epicontinental peri-Tethyan (− 7.

“…Studies of other Arctic areas (North Sea [Callomon 1975 and Svalbard [Rawson 1982]) for the same period show similar faunas to Greenland. In North Amer ica (Callomon 1984;; and for syn thesis see Poulton et al 1992) and Siberia (Meledina 1973, 1977; for synthesis see Sey et al 1992), faunas were initially similar to those of Greenland but then became distinct, and so regional scales have been constructed for these two areas. Correlations between these different regions of the Boreal Realm and be tween this realm and non-Arctic regions of North America ("Western Interior/' Terranes) are based on studies by Callomon (1984Callomon ( , 1993, , and Hillebrandt et al (1992).…”

“…The Cardioceratidae lineage is one of the beststudied faunas of the Boreal Realm. The first forms appeared in this previously ammonitefree area at the onset of the late Bajocian: the last reported faunas in the area before the ad vent of the Cardioceratidae are dated to the early Toarcian in Greenland (Dam and Surlyck 1998;Surlyck and Noe-Nygaard 2000) and to the early Bajocian in the Arctic area of North America and Siberia (Poulton et al 1992;Sey et al 1992).…”

Multivariate analysis of shell characters and quantification of morphological diversity (morphospace occupation and disparity) are used here to investigate the modes of morphological diversification of ammonites. We define five events in early cardioceratid history that connect geo graphical changes causing emigration or immigration phases with biodiversity dynamics: (1) the initial colonization of the Arctic Basin by the Cardioceratidae at the end of the Bajocian, Middle Jurassic; (2) the first appearance of the Kosmoceratidae clade in the Boreal Realm during the Bathonian; (3) the ensuing expansion phase of this clade in the Boreal Realm; (4) the first phase of migration of the Cardioceratidae (early Callovian) through Eastern Europe, Western Britain and the Yukon corridor; and (5) the second unrelated migration phase in the Western Interior only. Analysis of spatial occupation shows that acquisition of this field occurs essentially by replacement or subdivision of preexisting peaks of occupation. These replacements seem to follow different patterns: progressive trend, saturation, iteration, and apparent preferential extinction. We describe these patterns and suggest different factors that may have shaped them, including a morphological differentiation that has been interpreted by various authors as sexual dimorphism. Another factor that could cause disparity modification is fluctuations in the ammonites' proximal environment. The effect of immigrating faunas is a third (and preponderant) factor that is prominent in the stud ied example: immigration phases of the Cardioceratidae lead to increased morphological diversity, whereas the spread of nonindigenous species reduces it and is contemporaneous with a morpho logical shift in the native clade. We thus demonstrate here that geographical constraints play a significant role in the expression of innovation and may be seen as a major factor in macroevolutionary dynamics.

The Lower Jurassic Higuchi Group, exposed in the western part of Shimane Prefecture, Japan, includes, in ascending order, the Orojidani and Higuchidani formations. The Orojidani Formation is composed of conglomerate, sandstone, and mudstone, the latter containing Oxytoma sp. and Pleuromya sp. The Higuchidani Formation consists mainly of dark gray mudstone, from which six genera and six species of bivalves were collected: Kolymonectes staeschei, Palmoxytoma cygnipes, Ryderia texturata, Pseudomytiloides matsumotoi, Oxytoma sp., and Pleuromya sp. This bivalve assemblage is characterized by Boreal elements such as K. staeschei and P. cygnipes, which are known exclusively from the Lower Jurassic of Russia and northern Canada; it contains no typical Tethyan species.
