Late Campanian–Maastrichtian sequence stratigraphy from Kurdistan foreland basin, NE/Iraq

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The Kurdistan foreland basin (NE Iraq) was formed as a result of the ophiolite–radiolarites obduction of the Iranian plate on the Arabian Plate. Extensive fieldwork for the determination of nine facies associations has been integrated with the planktonic

Maastrichtian ammonites from Balochistan, Pakistan

open access: yesJournal of Paleontology, 1999
Maastrichtian ammonites are described from two areas in Pakistan. The upper part of the lower unit of the Korara Shale in the southern Pab Range, Kirthar Province, southern Balochistan, is dated as Late Maastrichtian, based on the presence ofMenuites fresvillensis(Seunes, 1890), which is accompanied by abundantIndoceras baluchistanenseNoetling, 1897 ...

The 150th anniversary of the Maastrichtian Stage - a celebratory conference: Introduction [PDF]

open access: yesNetherlands Journal of Geosciences - Geologie en Mijnbouw, 2003
It was André Hubert Dumont (1809–1857) (Fig. 1) who, while mapping at the St Pietersberg south of Maastricht in the summer of 1849, noted that the higher portion of the yellowish-white friable limestones exposed there represented something unique. So unique that he coined a name for it (Dumont, 1849), his ‘système maestrichtien’, with a fossil hash ...

Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.
