Comparing the Development and Viability of Horseshoe Crab Eggs Laid in Beach and Salt Marsh Habitats

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Recent research has found that horseshoe crabs spawn regularly in salt marshes. However, it remained unclear if eggs laid in salt marsh sediments are viable. In this study, we show that eggs laid in salt marsh habitats develop similarly to those laid in beach habitats, suggesting that salt marshes are viable spawning habitats for horseshoe crabs ...

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

Digestive and appendicular soft-parts, with behavioural implications, in a large Ordovician trilobite from the Fezouata Lagerstätte, Morocco [PDF]

, 2017
Trilobites were one of the most successful groups of marine arthropods during the Palaeozoic era, yet their soft-part anatomy is only known from a few exceptionally-preserved specimens found in a handful of localities from the Cambrian to the Devonian ...

Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

The Depositional Record, Volume 11, Issue 5, Page 1563-1595, November 2025.
This study integrates sedimentological and ichnological data to reveal the depositional processes and environmental conditions of deep‐water muddy gravity flows in the Mobarak Formation. It highlights distinct ichnocoenoses and bioturbation patterns, offering insights into basin‐floor versus slope mudstones and their implications for hydrocarbon ...

Geometry and Kinematics of the Hormuz Salt at Jebel Al Dhanna, United Arab Emirates: Implications for Salt Tectonics and Subsurface Storage

Tectonics, Volume 44, Issue 11, November 2025.
Abstract The United Arab Emirates government is assessing the potential of Hormuz Salt domes for subsurface storage, aligning with the transition toward clean energy systems and carbon reduction goals. However, the geometry, kinematics, and halokinetic evolution of these salt structures remain poorly constrained.

Orbitally‐Driven Nutrient Pulses Linked to Early Cambrian Periodic Oxygenation and Animal Radiation

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract During the Cambrian Explosion, episodic radiations of major animal phyla occurred in concert with repeated coupled carbon‐sulfur isotope excursions. These isotope patterns are thought to reflect oscillations in atmospheric and shallow‐marine O2, which promoted animal diversification events. However, the driver for oxygenation pulses is unclear.

Late Middle Cambrian trilobites from Trial Ridge, southwestern Tasmania [PDF]

, 2001
The first Middle Cambrian trilobites to be described from southwestern Tasmania come from two localities within siltstone in the Trial Ridge area on the HUNTLEY 1:50 000 sheet. Sixteen trilobite taxa are described.
