Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

open access: yes, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Lower Glacial Oxygen in the Eastern Equatorial Pacific Concentrated in the Deep Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Oxygen in the global oceans has declined since the 1960s, including in the Eastern Equatorial Pacific (EEP). Reconstructions of EEP glacial oxygenation help advance understanding of current and projected ocean deoxygenation. Previous estimates of the glacial oxygen deficient zones (ODZs) in the upper EEP are poorly constrained. Here we include

Three hundred eighty thousand year long stable isotope and faunal records from the Red Sea : influence of global sea level change on hydrography [PDF]

open access: yes, 1996
Stable isotope and faunal records from the central Red Sea show high-amplitude oscillations for the past 380,000 years. Positive δ18O anomalies indicate periods of significant salt buildup during periods of lowered sea level when water mass exchange with

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Sediment‐stressed reefs over the past 420 Myr

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

A tubular protozoan predator: a burrow selectively filled with tubular agglutinated protozoans (Xenophyophorea, Foraminifera) in the abyssal South China Sea [PDF]

open access: yes, 2004
We report the occurrence of an unusual agglutinated protozoan-filled burrow recovered in a box core collected in 1998 from a depth of 2496 m in the South China Sea.

Comment on Reply to Comment of Finger et al. (2013) on: 'Evidence for an Early-Middle Miocene age of the Navidad Formation (central Chile): Paleontological, paleoclimatic and tectonic implications' of Gutiérrez et al. (2013, Andean Geology 40 (1): 66-78) [PDF]

open access: yes, 2014
Indexación: Web of Science; ScieloIn their answer to our Comment (Finger et al., 2013), Le Roux et al. (2013) misunderstand several of our remarks and present what we view as f lawed arguments, principally their case for a shallow-marine environment for ...

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Ecology of foraminifera during the middle Eocene climatic optimum in Kutch, India

open access: yesGeodinamica Acta, 2017
The shallow marine carbonates of Kutch temporally correspond to the globally recognised warming period called Middle Eocene Climatic Optimum (MECO) that extended from later part of planktic foraminiferal zone E11 to E12 and Shallow Benthic Zone (SBZ) 17.
