Late Cretaceous–Paleocene Depsits

2020
Preceding studies divided the Late Cretaceous deposits in the Cyrenaica Basin into two parts: the first part was deposited on the coast (Al Hilal and Al Athrun formations) and the second part in the inland (Qasr Al Abid, Al Baniyah, Al Majahir and Wadi Dukhan formations).

Baja California: Late Cretaceous Dinosaurs

Science, 1967
Late Cretaceous dinosaurs have been discovered along the Pacific margin of Baja California. The presence of Hypacrosaurus sp. is suggestive of correlation with the Upper Edmonton Formation, Alberta. Dissimilarities between the Baja California fauna and those from contemporary units along the eastern trend of the ...

Late Cretaceous chrysomonad cysts

Palaeogeography, Palaeoclimatology, Palaeoecology, 1972
Abstract An abundant and diverse chrysomonad-cyst flora is present in the Marca Shale Member of the Moreno Formation of California. Associated with the siliceous cysts are diatoms, silicoflagellates, radiolarians, and, rarely, Foraminifera. Five preliminary biostratigraphic zones, based on variations in the kinds and quantities of cysts present, are ...

Late Cretaceous Antarctic fish diversity

Geological Society, London, Special Publications, 2006
Abstract New material from the Santa Marta Formation (late Coniacian-?early Maastrichtian) of James Ross Island contributes significantly to the current knowledge of Late Cretaceous Antarctic fish diversity. The taxon list for the Santa Marta Formation is extended, and new records of neoselachians and teleosts are reported.

Aptychi microstructure in Late Cretaceous Ancyloceratina (Ammonoidea)

Lethaia, 2009
The microstructure of aptychi (bivalved calcareous coverings on lower jaws) of three genera of Late Cretaceous Ancyloceratina, Baculites, Polyptychoceras and Jeletzkytes is described for the first time on the basis of well-preserved and in situ material from the Western Interior of the USA and Hokkaido, Japan.

Late Cretaceous lithoevents in the Bohemian Cretaceous Basin, Czechoslovakia

Cretaceous Research, 1991
Abstract Facies evolution and vertical changes within the Late Cretaceous sequence of the Bohemian Cretaceous Basin reveal fluctuations of intra- and extrabasinal circumstances. Evidence of periodic oscillations is recognized and two categories of aperiodic event indications are distinguished according to their significance and lateral persistence ...

Cosmopolitanism among Gondwanan Late Cretaceous mammals

Nature, 1997
Consistent with geophysical evidence for the breaking up of Pangaea, it has been hypothesized that Cretaceous vertebrates on progressively isolated landmasses exhibit generally increasing levels of provincialism1,2,3, with distinctly heightened endemism occurring at the beginning of the Late Cretaceous4.

Late Cretaceous mammals (Marsupialia) from Bolivia

Geobios, 1983
Abstract A second Late Cretaceous (Maestrichtian Age)mammal fauna for South America was recovered from the El Molino Formation in southcentral Bolivia. Three species are referred to the marsupial super-family Didelphoidea. The most abundant species has marked bunodont dental specializations which are convergent with some early placental Condylarthra;

The Late Jurassic–Early Cretaceous Rifting

2019
During the Late Jurassic and Early Cretaceous, Iberia experienced extensional and transtensional stresses leading to a complex rifting time interval. Africa–America–Europe relative motions determined the definition of the Iberian plate boundaries and the generation of rifted sedimentary basins and sub-basins along its continental margins and in the ...
