Milankovitch Cyclicity and Stable Isotope Calibration in the Paleogene (invited)
, 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).

Evolution in arid environments: the role of betalains, succulence, and medullary bundles
New Phytologist, EarlyView.Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

The utility of deep-water agglutinated Foraminiferal acmes for correlating Eocene to Oligocene abyssal sediments in the North Atlantic and Western Tethys [PDF]
, 2005 Quantitative analysis of Deep-water Agglutinated Foraminifera (DWAF) assemblages from key ODP sites in the North Atlantic reveal the presence of stratigraphically-significant abundance maxima, that may be useful for correlating sedimentary sequences ...

Sedimentology, EarlyView.ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...

Comments on the Caribbean Oligocene [PDF]
Geological Magazine, 1954 An objection is raised to the identification of beds in the Caribbean area as Miocene on the basis of the presence of Miogypsina, as proposed by Eames. Basal Camana beds in southern Peru contain Miogypsina and are Oligocene on the basis of correlation with beds in Ecuador.

Zoologica Scripta, EarlyView.ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...
