Abstract. Sea surface temperature (SST) reconstructions based on isoprenoid glycerol dialkyl tetraether (isoGDGT) distributions from the Eocene southwest (SW) Pacific Ocean are unequivocally warmer than can be reconciled with state-of-the-art fully coupled climate models. However, SST signal preserved in sedimentary archives affected by contributions of additional isoGDGT sources. Methods now e...

2D multi-channel seismic profiles and a 3D survey were utilised together with potential field available well data to study the late Mesozoic-Cenozoic tectono-stratigraphic evolution of northern Lofoten-Vesterålen margin, offshore Norway. The analysis resulted in an updated structural stratigraphic framework, new better refined elements. Distinct along-margin basin segmentation is evident impose...

The Late Cretaceous-Early Paleocene Shiranish and Aliji formations have been studied in three selected wells Jambur Oil Field (Ja-50, Ja-53, Ja-67) Kirkuk, Northeastern Iraq. This study included lithostratigraphy biostratigraphy. Campanian-Maastrichtian Formation consist mainly of thin marly chalky limestone beds overlain by marl beds, with some representing an outer shelf basinal environment, ...

new evidence gained by the study of foraminifera from khuzestan province in southwest iran reveals that the basal limit of the genus heterostegina is not restricted to the eocene epoch. by introducing a new species of this genus (h. rezvaninejadi), this study shows that the early appearance of this genus should be lowered down further still, at least, into the middle paleocene.

The Sheep Creek camp straddles the eastern boundary o' the Kootenay arc. This arcuate belt of deformed and meta morphosed rocks has had a complex history of Mesozoic ant1 Paleocene compressional and transpressional defo!nnatiol~ overprinted by Eocene extensional tectonics. The rocks an: believed to represent both a distal continental margin and part of a late Paleozoic to early Mesozoic back-ar...

Several specimens from the Lias Group (Lower Jurassic) of Northern Ireland have been suspected as dinosaurian in origin. Bone histology and morphology demonstrates that two these, both same locality Co. Antrim, demonstrably are dinosaurs. We interpret one proximal end left femur a basal thyreophoran ornithischian, tentatively assign it to cf. Scelidosaurus. The other is part tibia an indetermin...
