Milankovitch Cyclicity and Stable Isotope Calibration in the Paleogene (invited) [PDF]

, 2003
Significant progress has been made over the last decade in the extension of astronomically calibrated geological time scales for the Neogene (Hilgen et al., 1999, Shackleton et al., 1999).

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Review and revision of Cenozoic tropical planktonic foraminiferal biostratigraphy and calibration to the Geomagnetic Polarity and Astronomical Time Scale [PDF]

, 2010
Planktonic foraminifera are widely utilized for the biostratigraphy of Cretaceous and Cenozoic marine sediments and are a fundamental component of Cenozoic chronostratigraphy.

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Oligocene-Miocene strontium isotopes of ODP Hole 120-747A [PDF]

, 1994
This study tests and improves on previously published early and middle Miocene 87Sr/86Sr marine correlations, presents Sr isotopic age correlations for this interval using the new timescale of Cande and Kent [1992 doi:10.1029/92JB01202], and evaluates Sr

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...
