Quantitative analysis of palaeoecological features and paleobiogeographic setting of brachiopod fauna in the Julfa Formation (Early Lopingian), northwest Iran [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2018
Introduction Lopingian succession in the vicinity of Julfa (East Azerbaijan Province, NW Iran) have been known for a long time among the most fossiliferous sections in the south of Paleotethys, especially those of the Ali Bashi Mountains (Stepanov et al ...

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

The first data on the innervation of the lophophore in the rhynchonelliform brachiopod Hemithiris psittacea: what is the ground pattern of the lophophore in lophophorates?

open access: yesBMC Evolutionary Biology, 2017
Background The nervous system in brachiopods has seldom been studied with modern methods. An understanding of lophophore innervation in adult brachiopods is useful for comparing the innervation of the same lophophore type among different brachiopods and ...

Genetic Reference Gaps Limit eDNA Metabarcoding and Biodiversity Monitoring of Tropical Mangrove Ecosystems

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
This review reveals major genetic data gaps for Philippine mangrove fauna, especially invertebrates, limiting species‐level eDNA detection. By compiling 48 years of biodiversity records and assessing reference library coverage, it highlights the need for targeted sequencing and shows how integrating eDNA with conventional surveys strengthens monitoring

Permian productidina of Britain and Malaysia [PDF]

open access: yes, 1990
The British Permian Productidina have not been revised in detail since 1858. In the present study some 2000 specimens from 29 localities in north east of England have been collected and prepared in the laboratory and used together with museum collections.

Biogenic calcite granules — are brachiopods different?

open access: yes, 2013
Brachiopods are still one of the least studied groups of organisms in terms of biomineralization despite recent studies indicating the presence of highly complex biomineral structures, particularly in taxa with calcitic shells.

Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.

Siliceous tablets in the larval shells of apatitic discinid brachiopods

open access: yes, 1998
The marine bivalved Brachiopoda are abundant throughout the geological record and have apatitic (CaPO4-rich) or calcitic (CaCO3-rich) shells. Vesicles covering the larval valves of living apatitic-shelled discinids contain tablets of silica.
