Ammonite Faunal Dynamics Across Bio−Events During the Mid− and Late Cretaceous Along the Russian Pacific Coast
Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast ELENA A. JAGT−YAZYKOVA Jagt−Yazykova, E.A. 2012. Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast. Acta Palaeontologica Polonica 57 (4): 737–748. The present paper focuses on the evolutionary dynamics of ammonites from sections along the Russian Pacific coast dur− ing the mid− and Late Cretaceous. Changes in ammonite diversity (i.e., disappearance [extinction or emigration], appear− ance [origination or immigration], and total number of species present) constitute the basis for the identification of the main bio−events. The regional diversity curve reflects all global mass extinctions, faunal turnovers, and radiations. In the case of the Pacific coastal regions, such bio−events (which are comparatively easily recognised and have been described in detail), rather than first or last appearance datums of index species, should be used for global correlation. This is because of the high degree of endemism and provinciality of Cretaceous macrofaunas from the Pacific region in general and of ammonites in particular.

Preliminary Notes on the Cretaceous Ammonite Faunas of East Greenland by L

F. SPATH D.Sr.., F. R.S. K0 BENHAVN C. A. REITZELS FORLAG BIANCO LUNOS BOGTRYKKKKI 1946 retaceous ammonites have long been known from East Greenland C but the list of the few, more or less isolated finds is not impressive. Thus Toula’s (1874) widely-quoted Amm. payeri, first referred to the genus Perisphinctes, was subsequently considered to be a form of Sim- birskites and was held to demonstrate the presence of marine Hauterivian deposits. This is almost certainly incorrect, as mentioned below. Again one of Ravn’s (1912) two ammonites was misidentified as a Neocomian “Garnieria”, whereas in reality it represents the inner whorls of an Aptian genus (Sanmartinoceras). A few additional species were recorded by Koch (1929, 1931), Rosenkrantz (1930, 1934), Frebold (1935) and Maync (1940), again mostly of Aptian age. The purpose of the present note is not only to amplify these records but to announce the discovery of entirely new ammonite assemblages of Cretaceous age. The new collections were made during the 1936—1938 expedition to East Greenland under the leadership of Dr. Lauge Koch, and the collectors of the material now before me were two competent Swiss geologists. One of them, Dr. Hans Stauber, worked in Traill Island and Geographical Society Island. The other, Dr. Wolf Maync, collected in the northern area, from Clavering Island up to Kuhn Island. -

Abstract: Most of the known ammonite faunas from the Albian to Middle Cenomanian formations of Korjak-Kamchatka, northeastern Russia, are revised and summarized. 7 poorly known species are described. 22 other species are illustrated and mentioned in the discussion. A new ammonite zonal scheme is proposed for the Albian to Middle Cenomanian of the region. Zusammenfassung: Die meisten Ammonitenfaunen des Albs bis Mittel-Cenomans von Korjak-Kamtschatka (NE Rußland) werden zusammengefaßt und revidiert. 7 weniger bekannte Arten werden beschrieben. 22 weitere Arten werden diskutiert und abgebildet. Als Ergebnis wird ein neues Ammoniten-Zonen-Schema für das Alb bis Mittel-Cenoman der Region vorgestellt. 1. Introduction Albian to Cenomanian sedimentary formations are exposed along the axial part of Korjak-Kamchatka, a main Mid-Cretaceous depocenter in the Pacific margin of NE Russia (Fig. 1). The rocks were deposited in the miogeosynclinal trough between the foreland of the Okhotsk-Chukchi volcano-plutonic belt and a system of island arcs, which migrated towards the foreland during the Albian and away from it since the Cenomanian (ALABUSHEV & WIEDMANN 1994b, ALABUSHEV, in press). The most complete Mid-Cretaceous successions of true marine deposits are known in the western Korjak-Kamchatka, namely: Talovka and Penzhina river basins (Fig. -

The Jurassic and Cretaceous Sequence in Spitsbergen
The Jurassic and Cretaceous Sequence in Spitsbergen The Jurassic and Cretaceous sequence of Spitsbergen, Svalbard archipelago, is described and a revised lithostratigraphical scheme, of four formations, is proposed. The main episode of tectonic activity, together with dolerite intrusion, was in late Jurassic-early Cretaceous times and is represented by a non-sequence and local unconformity between the two lower formations. The fauna1 succession is also discussed. THEJurassic and Cretaceous rocks of Spitsbergen are exposed as an elliptical outcrop around the main Tertiary syncline (Text-fig. 1 ). Along the west coast the rocks have been folded and thrust in a deforma t'Ion belt of Tertiary age but in the north and east are gently dipping and little deformed, apart from local activity along fault belts. Jurassic fossils were first collected from Spitsbergen by Lovtn in 1837 from Grsnfjorden, and subsequent expeditions, led principally by Nordenskiold and Nathorst, established the presence of Jurassic and " Neocomian " strata along the south side of Isfjorden, in Bellsund, at Agardhbukta on the east coast, and on Kong Karls Land, the group of islands which lie some 150 km east of Vestspitsbergen. The results of these early expeditions were summarized by Nathorst (1910). Subsequent palaeontological work was based mainly on material from the Festningetl section (Hoel and Orvin, 1937; Sokolovand Bodylevsky, 1931 ; Frebold and Stoll, 1937) but much information on other localities and collections was given in a series of papers by Frebold (1929 a-c, 1930, 1931) who also discussed the palaeogeography and correlation of the Arctic Jurassic and Cretaceous rocks. Useful summaries of the Jurassic-Cretaceous sequence were given by Frebold in his two reviews of Spitsbergen geology (1935, 1951) and Arkell (1956) has, in particular, discussed the Jurassic faunas.
