High‐Resolution Anisian Marine Perturbation by Volcanism in the Eastern Paleo‐Tethys

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Following the end‐Permian mass extinction, the Middle Triassic Anisian Stage was still characterized by environmental perturbations that hindered biological flourishing, yet it remains uncertain whether these persistent Tethyan disturbances were coupled with the closure of the Paleo‐Tethys Ocean.

lntraspecific Variation Within the Conodont Polygnathus brevilamina [PDF]

open access: yes, 1966
Intraspecific variation was observed in a study of 177 well preserved specimens of the conodont Polygnathus brevilamina. Variations in the size of platform and in the degree of ornamentation of the platform are illustrated.

Emplacement of Hybrid Continental‐Oceanic Arc Terranes Without Collision: The Devonian Calliope Arc (New England Orogen, Australia)

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract The accretion of allochthonous provinces, derived from oceanic plates, has traditionally been considered an important contributor to continental growth. However, increasing evidence shows that some oceanic terranes (e.g., island arcs) are not “exotic,” as suggested by the presence of continental‐derived sedimentary provenance.

Unaltered evidence: comparing oxygen isotopes in conodonts from deep‐sea chert analysed in situ and extracted using NaOH

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract The oxygen isotope composition (δ18O) of conodont biogenic apatite is a critical proxy for reconstructing past marine temperatures and environments. This study compares δ18O values of Triassic conodonts embedded in chert with those extracted from the same samples using sodium hydroxide (NaOH), a novel alternative to traditional hydrofluoric ...
