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 ...

New records of teleosts from the Late Turonian (Late Cretaceous) of the Bohemian Cretaceous Basin (Czech Republic)

Cretaceous Research, 2008
New discoveries of articulated partial skeletons of teleosts from Upper Turonian strata in the Bohemian Cretaceous Basin (BCB) are described. The infrequent occurrence of articulated skeletons is discussed and compared with comparable taxa from the same time-equivalent successions in southern England.

Late cretaceous and paroxysmal cretaceous/tertiary extinctions

Deep Sea Research Part B. Oceanographic Literature Review, 1987
The various geological signatures at Cretaceous/ Tertiary time including iridium and other associated elements, microspherules, and shock deformation features are compatible with the suggestion that the transition is marked by a period of intense volcanism.

Migration of a Late Cretaceous fish

Nature, 2003
Late Cretaceous sediments from the Western Interior of North America yield exceptionally well preserved fossils that serve as proxies for the rapidly changing climate preceding the Cretaceous/Tertiary boundary (about 67-65 Myr ago). Here we reconstruct the ontogenetic history of a Maastrichtian-age fish, Vorhisia vulpes, by using the carbon, oxygen and

Late Cretaceous Reversal Sequence

Geology, 1975
A sequence of 14 reversals (that is, seven periods of reversed polarity) is observed in Maestrichtian sedimentary rocks from the Mendez Shale of Mexico and in cores from Deep Sea Drilling Project Sites 207A and 208, Lord Howe Rise. Data from a paleomagnetic investigation indicate that (1) a brief interval of frequent field reversals occurred at the ...

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).

Caryanthus diversity in the Late Cretaceous

Review of Palaeobotany and Palynology, 2016
Abstract Genus Caryanthus with fourteen species represents the most diversified genus in the Normapolles complex. Detailed review of material from Central Europe allowed accurate study of its geographic and stratigraphic distribution. An emended diagnosis of Caryanthus communis Knobloch et Mai, Caryanthus deltoides (Knobloch) Friis, Caryanthus
