Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle

Palaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

The Large Carpenter Bees (Xylocopa, Apidae) of the Neotropical Region: Phylogenetics, Classification and Biogeography

Zoologica Scripta, Volume 54, Issue 6, Page 884-896, November 2025.
ABSTRACT The large carpenter bees of the genus Xylocopa comprise almost 400 species distributed worldwide. Their large body and ability to build nests through woodworking make them one of the most remarkable groups of bees. In the Neotropics, they comprise over 100 species occurring in tropical and subtropical environments including islands in the ...

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.

Disentangling Continental Weathering During the Late Paleozoic Ice Age

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The consumption of atmospheric CO2 through continental weathering played a critical role in shaping the evolution of the late Paleozoic Ice Age (LPIA), presumably driven by the Hercynian orogeny and the evolution of terrestrial plants. However, the relative impacts of these two major drivers to continental weathering remain poorly constrained.
