Sequential Isotopic Analysis of Ammonite Aptychi
Stable oxygen and carbon isotope data from ammonite carbonate (CaCO3) shell material and/or aptychi can be interpreted to reveal information about paleoenvironmental conditions because oxygen isotope ratios can vary based on temperature and oxygen isotope composition of ancient seawater and carbon …

Biostratigraphy, lithostratigraphy, ammonite taxonomy and microfacies analysis of the Middle and Upper Jurassic of northeastern Iran
… discussed with special emphasis on the abundant ammonite fauna. They constitute a more or less continuous sequence, being confined by two tectonic events, one at the base, in the uppermost part of the Shemshak Formation (Bajocian), the so-called Mid-Cimmerian Event, the other one at the top …

Ammon in the Hebrew Bible: a Textual Analysis and Archaeological Context of Selected References to the Ammonites of Transjordan
… Bible because of the numerous references to the Ammonites (bene 'ammon) included in the historical and prophetic sections of the Hebrew canon. The book of Genesis traces the ancestry of the "Sons of Ammon" to an eponymous ancestor named Ben Ammi--son/grandson of Abraham's nephew Lot (Gen …

Turonian inoceramids and biostratigraphy of the Sergipe Basin, northeastern Brazil: an integrated study of the Votorantim and Nassau quarries
… basis of bed-by-bed collecting of inoceramids, ammonites and other macrofossil groups from the Votorantim (locality Retiro 26) and Nassau (locality Mata 11) quarries in the Laranjeiras–Nossa Senhora do Socorro area. The inoceramids are described systematically with the aim of providing a …

Albian microbiostratigraphy (foraminifera and Ostracoda) of S.E. England and adjacent areas
… foraminifera, to correlate it with the existing Ammonite zonal scheme, and propose a detailed zonation based on Ostracoda which have been integrated with both the zonal schemes mentioned above. To achieve this, the stratigraphically most continuous sections were examined.

High-Precision ID-TIMS U-Pb Zircon Geochronology of Three Cenomanian Bentonites from the Western Canada Foreland Basin
… basin where relationships to globally correlated ammonite zones can be determined. The X, A-X and Bighorn River bentonites provide important calibration points for the Cenomanian Stage. Single zircon crystals from these bentonites were chemically-abraded and dated using high-precision U-Pb ID-TIMS …

Palaeontology and biostratigraphy of the Lower Cretaceous Qihulin Formation in eastern Heilongjiang, northeastern China
… collected fossil groups, i.e. the macrofossils (ammonites and bivalves) and microfossils (agglutinated foraminifers and radiolarians) have been studied. The low-diversity ammonite fauna consists of Pseudohaploceras Hyatt, 1900, and Eogaudryceras Spath, 1927, which indicate a Barremian-Aptian age. …

Stable Carbon and Nitrogen Isotopes of Shell Bound organic Matter, Implications for Modern and Ancient Food Web Dynamics
… about a long-extinct enigmatic heteromorph ammonite, Baculites. Contrary to the usual understanding that ammonites were nektonic carnivores, δ15N and δ13C analysis of shell associate OM from Baculites and co-occurring ammonite Hoploscaphites reveal that they were planktivores and actively …

The palaeoenvironments and stratigraphy of the Lincolnshire Limestone Formation (Middle Jurassic: Bajocian) of Northamptonshire and southern Lincolnshire
… Subzone, consistent with parts of the (ammonite) Laeviuscula Zone age ascribed to at least part of the strata by earlier authors. The size distributions and morphological forms displayed by the ostracod and foraminifera faunas suggest periods of vegetative cover on the sea floor, periods …

The Jephthah Traditions : a Rhetorical and Literary Study in the Deuteronomistic History
… of Jephthah's effort at peaceful settlement of Ammonite aggression through diplomacy. Thus, the Jephthah stories are symmetrically arranged. The thematic over-arch is the establishment of a single-head government in Gilead under conditions of national repentance, foreign threat, and elders' …

Discovering the last Triassic giant: Insights from the marine Late Triassic of Nevada and a new ichthyosaur locality from New York Canyon, Nevada, USA.
… examples of Shonisaurus. Strong controls on ammonite biostratigraphy and organic carbon isotope geochemistry confirm that this specimen is the youngest shastasaurid ichthyosaur reported to date and indicates that these giant ichthyosaurs did not go extinct during the Norian. Instead, they …

The Palaeo-ecology and Biostratigraphy of the foraminifera from the Oxfordian of north Dorset
… is achieved using lithological techniques, ammonite zonation, foraminiferal biohorizons and the biofacies defined by multivariate analysis. A total of 21 biohorizons are identified with certain horizons coinciding with lithological boundaries and previously defined unconformities recognised …

Middle and upper jurassic foraminifera and radiolaria of Scotland : an integrated biostratigraphical and palaeoenvironmental approach
… is implicitly tied to the Boreal type ammonite scheme and comprises a total of 9 biozones and 12 sub-biozones. The new biozones are then correlated and compared with the other Scottish sites as well as other world-wide schemes.A sequential palaeoenvironmental analysis is outlined, …

THE SEDIMENTOLOGY, PETROLOGY AND STRATIGRAPHY OF THE UPPER GREENSAND IN S.W. ENGLAND
… are shown to result in a ghost fabric. A new ammonite occurrence is reported from the Foxmould Sands Member at Branscombe. Identified as Prohystoceras (Goodhallites) delabechei it suggests a varicosum Subzone age for the lower part of the Foxmould Sands Member. 23 genera and 32 species of …

The middle Jurassic of New Zealand : a study of the lithostratigraphy and biostratigraphy of the Ururoan, Temaikan and Lower Heterian Stages (?Pliensbachian to ?Kimmeridgian)
