  • World permo-triassic correlations: their biostratigraphic basis in Gondwana Five. Selected papers and abstracts of papers.
  • Amino acid enantiomeric (D/L) ratios in the mollusk Mercenaria are compared with recently published biostratigraphic and/or U-series solitary coral data from 22 Quaternary localities on the central and southern Atlantic Coastal Plain. In all cases
  • , local relative aminostratigraphic sequences are consistent with relative ages inferred from U-series or biostratigraphic data, although occasionally more depositional events are recognized by aminostratigraphic than biostratigraphic methods. However
  • Biostratigraphic and geomorphic investigations in areas of Hungary subsided during the Holocene
  • Depositional environments and history of Late Quaternary sediments in Hudson Strait and Ungava Bay : further evidence from seismic and biostratigraphic data
  • Biostratigraphic ages of Tertiary basalts on the East Greenland continental margin and their relationship to plate separation in the Northeast Atlantic
  • Biostratigraphic evidence of the Allerød-Younger Dryas-Preboreal oscillation in northern Iceland
  • Foraminiferal Biostratigraphic and Paleobathymetric constraints in Geohistory analysis : the example of the Epiligurian succession of the Secchia Valley (Northen Apennines, Mid Eocene-Late Eocene)
  • An attempt at synthesizing the Holocene biostratigraphy of a type area in northern Norway by means of recommended methods for zonation and comparison of biostratigraphical data
  • Biostratigraphical evidence for Late Weichselian and Holocene sea-level changes in southern Norway in Shorelines and isostasy.
  • Litho-and biostratigraphical study of Quaternary deep marine deposits of the Western Belgian coastal plain
  • The objectives of this paper are to present the Llandovery graptolite biostratigraphy of the Cape Phillips Formation, with illustrations of the more common and biostratigraphically important taxa, and to discuss the paleobiogeographic aspects
  • A biostratigraphic classification of marine Paleogene deposits as applied in stratigraphic interpretations. Seven biozones are distinguished mainly on the basis of differences in the composition of benthonic foraminiferal assemblages. (AIS).
  • Biostratigraphic constraints and depositional environment of the Lower Cretaceous (Albian) Boulder Creek Formation, Monkman area, northeastern British Columbia
  • Shore-level changes in South Norway during the last 13,000 years, traced by biostratigraphical methods and radiometric dating
  • The micromammal fauna of the Dnieper modern channel alluvium : taphonomic and biostratigraphic implications
  • Based on phylogenetical, palaeoecological and biostratigraphical studies on the Holocene malacofauna of Hungarian medium high mountains and flatlands, four faunal periods could be recognised in the mountains, while three ones on the flat regions
  • Palynological investigations of earliest Pleistocene deposits at Frechen, some ten kilometers West of Cologne permit the dating of these sediments in terms of the Dutch biostratigraphic scale. Of special interest is a newly discovered interglacial
  • Two samples from southern Mauritania yielded pollen grains. One of them is of pedologic origin, the other contains some diatoms. Discussion of results emphasize quite a good agreement of data with the biostratigraphic contexte but neither in one
  • , accompanied by structural interpretation and biostratigraphic analyses. - (NF)
  • Opinions differ as to whether the true red clays mostly deposited on Upper Pannonian lacustrine sediments are dated as Pliocene or early Quaternary. Biostratigraphic and lithostratigraphic data show that these non-rewashed residual deposits of red
