The Maastrichtian – Danian at General Roca (Patagonia, Argentina): a reappraisal of the chronostratigraphy and biostratigraphy of a type locality
(E Schweizerbartsche Verlags, 2011-02)
The Late Cretaceous - Early Paleogene succession exposed in the type area of the Roca Formation (General Roca, Rfo Negro Province), has been sampled in detail. Analyses of the calcareous nannofossil assemblages indicate ...
Morphostatistical analysis of Maastrichtian populations of Guembelitria from El Kef, Tunisia
(Cushman Foundation for Foraminiferal Research, 2010-03)
Three species of Guembelitria with regular triserial arrangement are recognized in the late Maastrichtian, based on biometric measures of specimens from El Kef (Tunisia) and morphostatistical analysis. They are mainly ...
Late Maastrichtian to Danian organic-walled dinoflagellate cysts and calcareous nannofossils from eastern Austral Basin, Patagonia, Argentina
(Elsevier Science, 2021-02-02)
Late Maastrichtian to Danian dinoflagellate cyst and calcareous nannofossil biostratigraphy was analyzed at the Sur Río Chico borehole, Austral Basin, Argentina. Two stratigraphical intervals from the 965 to 1003 m below ...
A postcranial skeleton of an elasmosaurid plesiosaur from the Maastrichtian of central Chile, with comments on the affinities of Late Cretaceous plesiosauroids from the Weddellian Biogeographic Province
(2012)
An almost complete postcranial skeleton recovered from late Maastrichtian beds of central Chile, which can be confidently referred to the clade Elasmosauridae (Sauropterygia: Plesiosauroidea), is described. The material ...
Patterns of Late Cretaceous ammonite biogeography in southern high latitudes: The family Kossmaticeratidae in Antarctica
(Academic Press Ltd - Elsevier Science Ltd, 2000-01)
A refined biostratigraphy of the Antarctic kossmaticeratids from the James Ross Basin is contrasted against other Upper Cretaceous sections around southern Gondwana to inspect for possible biogeographic patterns. In the ...
