Correlation of Albian European and Tethyan Ammonite Zonations and the Boundaries of the Albian Stage and Substages: Some Comments
Correlation of Albian European and Tethyan ammonite zonations and the boundaries of the Albian Stage and substages: some comments Hugh G. Owen Owen, H.G. Correlation of Albian European and Tethyan ammonite zonations and the boundaries of the Albian Stage and substages: some comments. — Scripta Geol., Spec. Issue 3: 129-149, 5 figs., Lei• den, December 1999. H.G. Owen, Department of Palaeontology, The Natural History Museum, Cromwell Road, London SW7 5BD, England (UK). Key words: Early Cretaceous, Albian Stage, ammonite zonation, European and Tethyan faunal provinces Although the so-called 'standard' ammonite zonation of the Albian contains index species which occur in the Tethyan province, the scheme largely reflects the faunal succession in the European fau• nal province with its endemic sonneratiinid and hoplitinid faunal elements. Workers in the Tethyan province, stretching from South America in the west to Australia in the east, including southern Africa, Madagascar and India, face problems in the correlation of their successions with this so-called 'standard' scheme. There are other problems in that the succession of hoplitinid ammonites used in the biostratigraphy of European Albian sediments allows a far more detailed zonation to be made than in the case of some of the longer time-ranging Tethyan forms. This paper comments on propos• als made recently for the delimiting of the base of the Albian Stage, and the Middle and Upper Sub- stages, based on ammonite faunas. New information which affects the Albian ammonite zonation in the European faunal province and its correlation with the Tethyan province is discussed. The current hierarchical framework of zones and subzones used in the European faunal province may prove to be unsatisfactory in interprovincial correlation and particularly if the lower boundary of the Albian Stage was placed within the current Leymeriella tardefurcata ammonite Zone, instead of at its base. -

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.

A New Species of Lyelliceras (Ammonoidea, Lyelliceratidae) from the Albian (Lower Cretaceous) of France*
Netherlands Journal of Geosciences — Geologie en Mijnbouw | 90 – 2/3 | 95 - 98 | 2011 A new species of Lyelliceras (Ammonoidea, Lyelliceratidae) from the Albian (Lower Cretaceous) of France* W.J. Kennedy Oxford University Museum of Natural History, Parks Road, Oxford OX1 3PW, United Kingdom. Email: [email protected]. Manuscript received: October 2010, accepted: February 2011 Abstract A new lyelliceratid, Lyelliceras escragnollensis sp. nov., is described from the condensed Albian of Escragnolles (Var) and La Balme de Rencurel (Isère), as well as from the upper Lower or lower Upper Albian of Maurepaire (Aube), in France. The new species is precisely dated on the basis of a previous record from the lower Middle Albian Lyelliceras lyelli Subzone of the Hoplites dentatus Zone at Courcelles (Aube). It is regarded as a short-lived descendant of Lyelliceras pseudolyelli, and is characterised as a compressed species of the genus in which the inner ventrolateral tubercles are weak and apparently absent on the early phragmocone whorls, the outer ventrolateral clavi feeble, offset to opposite across the venter, the siphonal clavi being more numerous than the outer ventrolateral.

Excavations in 1989-1990 for the construction of a boat lift near the villages of Strépy and Thieu, east of Mons (province of Hainaut, southern Belgium), exposed a 40-metre section of the Bracquegnies Formation (Haine Green Sandstone Group; the ‘Meule de Bracquegnies’ of previous authors). Several hundred well-preserved, silicified cephalopods were collected from between 15 and 35 metres above the base of the sequence temporarily exposed there.

The Working Group proposes only one modification to its current zonation of the Mediterranean Region, the addition of a cristatum Subzone in the lower part of the inflatum Zone (upper Albian). But in the light of newly published research it highlights levels/areas where further work is required, especially to resolve conflicting zonal schemes. It also proposes a 'Tethyan Province' zonation for the middle Albian. Alternative correlations for the Boreal/Tethyan Valanginian to Barremian stages are tabulated, one based on ammonite evidence alone, the other with additional biostratigraphical data coupled with sequence stratigraphy and magnetostratigraphy.

Bull. Tokyo Gakugei Univ. Div. Nat. Sci., 69: 197-222 (2017) ISSN 1880-4330 Abstract Faunal analysis of the Cretaceous of Japan is indispensable to fully understand Early Cretaceous ammonite biostratigraphy and paleobiogeography in the northern regions of the circum-Pacific rim. The Lower Cretaceous in the Kochi Basin bears ammonite specimens. Eighteen Barremian to Aptian ammonite species including one new species (Pseudohaploceras tosaense) from the Kochi Basin, Japan, are described on the basis of 74 specimens. The ammonite specimens comprise three associations, lower, upper and uppermost. The lower association, from the Nagashiba Formation, comprises two species of two genera. The upper association, from the lower part of the Wada Formation, comprises 11 species of 9 genera. Then, the uppermost association, from the upper part of the Wada Formation, comprises eight species of eight genera. At the generic level, these ammonites occur commonly in the Barremian – Aptian (Lower Cretaceous) of Western and Eastern Europe, west – central and Southeast Asia, and the Pacific coast of North and South America. -
