The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

Tectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Trilobite Eyes and Their Evolution

Arthropoda
Trilobites, as typical euarthropods, possess compound eyes. In 1901, Lindström was the first to describe them in detail; on the one hand, we reconsider his descriptions of the different modes of trilobite eyes; on the other hand, we expand this by ...

Palaeoecology of Middle Devonian epizoans and their Paraspirifer hosts

Palaeontology, Volume 69, Issue 2, 2026.
Abstract The Silica Shale brachiopod, Paraspirifer bownockeri, of Ohio and Michigan, USA, preserves a unique window into Middle Devonian communities, as individuals hosted numerous epibionts. Herein, we use qualitative and quantitative methods to test hypotheses regarding the palaeoecology of these brachiopod hosts and their epibionts.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

Insect Science, Volume 33, Issue 1, Page 441-452, February 2026.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

Palaeoscolecids from the early Cambrian Guanshan biota, Yunnan Province, China

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract Palaeoscolecidomorphs (Palaeoscolecida and Cricocosmiidae) are widespread early Palaeozoic worms crucial to understanding the early evolution of Ecdysozoa. They are well known from the early–middle Cambrian of the Yangtze Platform of South China, but research has disproportionately focused on the well‐known Cambrian Stage 3 Chengjiang biota of

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 ...
