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 ...

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 ...

Modelling palaeophotosynthesis: late Cretaceous to present

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1994
This paper presents an attempt to reconstruct potential changes in the photosynthetic rates of terrestrial C3 leaves over the past 120 Ma. The approach has been to couple palaeoatmospheric reconstructions of O2, CO2and temperature from geochemical modelling, and an independent estimate of ancient CO2changes from fossil porphyrins, with a mechanistic ...
