The palaeoecology of two Scottish encrinites: Jurassic crinoid assemblages from the Trotternish Peninsula, Isle of Skye, Scotland [PDF]

, 2009
Despite a long history of investigation, articulate crinoids from the Jurassic of Scotland have not received great attention compared to their counterparts in Southern England or continental Europe; this is thought to be largely due to poor preservation.

Detrital Zircon Data Support Stronger, Inland‐Tracking Hurricanes During the Miocene Climatic Optimum, Maryland USA

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Climate models run under warmer‐than‐modern conditions indicate that hurricanes pass closer to the US East Coast and show that a higher proportion of tropical cyclones achieve “major hurricane” strength with winds >209 km/hr. Empirical observations indicate that the dominant southward longshore current direction off the US East Coast is ...

Pangean (Late Carboniferous–Middle Jurassic) paleoenvironment and lithofacies

Palaeogeography, Palaeoclimatology, Palaeoecology, 2000
Abstract Six time interval maps were constructed that depict the plate tectonic configuration, paleogeography and lithofacies for Pangea from the Late Carboniferous through the Middle Jurassic. Generally, the individual maps illustrate the conditions present during the maximum marine transgressions of higher frequency cyclicity within the Absaroka ...

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Field trip guide to Oligocene Limestones and Caves in the Waitomo District [PDF]

, 2013
The field guide runs from Hamilton to Waitomo to Te Anga and return in limestone-dominated country developed in transgressive sedimentary deposits of the Oligocene Te Kuiti Group – a world class example of a temperate shelf carbonate depositional system.

High-resolution truncated plurigaussian simulations for the characterization of heterogeneous formations [PDF]

, 2009
Integrating geological concepts, such as relative positions and proportions of the different lithofacies, is of highest importance in order to render realistic geological patterns.

Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

Sedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.
