BRACHIOPOD ASSEMBLAGES OF THE EURYDESMA FAUNA IN GLACIAL- DEGLACIAL SEQUENCES FROM ARGENTINA AND AUSTRALIA

Rivista Italiana di Paleontologia e Stratigrafia, 2019
The Eurydesma Fauna characterizes the Late Pennsylvanian-Permian glacial-postglacial sediments recorded in several Gondwanan basins during the Late Paleozoic Ice Age (LPIA).

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

Journal 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 ...

Hydrothermal dolomitisation of a deep‐water bioherm isolated in a non‐dolomitised intraplatform basin within the Norian Dolomia Principale (Southern Alps, northern Italy)

The Depositional Record, Volume 12, Issue 1, February 2026.
We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

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?

BMC 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 ...

Invertebrate Biodiversity Associated With a Unique Bryozoan Biogenic Reef Complex (Western Port, Victoria, Australia)

Austral Ecology, Volume 51, Issue 2, February 2026.
ABSTRACT A unique biogenic bryozoan reef has been recently discovered in Western Port (a temperate embayment), Victoria, Australia. This reef is significant owing to its contiguous, regular, linear rows of densely stacked bryozoan colonies with large vertical relief. We aimed to (1) document the biodiversity of the macroinvertebrate epifauna associated

Pigment‐Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials

Chemistry–Methods, Volume 6, Issue 1, January 2026.
A methodology has been developed to extract the colored organic fraction occluded within seashell biomineral waste. Applied to sea urchin skeletons, free polyhydroxylated naphthoquinone (PHNQ) pigments and PHNQ‐macromolecule complexes are isolated. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

Crystal Organisation of Muscle Attachment Sites of Bivalved Marine Organisms: A Juxtaposition Between Brachiopod and Bivalved Mollusc Shells

Crystals
The movement of valves of bivalved invertebrates is enabled through the action of muscles and the interplay between the muscles and the hinge ligament. The muscles that move the valves attach to their internal surface. To promote the structural integrity

Sections in the western slope of the south urals perspective for the choice of the famennian regional boundary stratotype point

Литосфера, 2015
The Bol’shaya Barma, Akkyr, Ryauzyak and Kuk-Karauk sections in the western slope of the South Urals are considered to be perspective sections for the identification of Famennian Regional Boundary Stratotype Point (RBSP).

Lower Silurian biostratigraphy of the Viirelaid core, western Estonia [PDF]

Estonian Journal of Earth Sciences, 2007
The distribution of five groups of fossils in the upper Llandovery (Telychian) and Wenlock of the Viirelaid core section, Estonia, is presented and discussed in terms of their biozones (conodonts and chitinozoans) and mutual positions (scolecodonts ...
