A new genus of Triassic discinid brachiopod and re-evaluating the taxonomy of the group—evolutionary insights into autecological innovation of post-Palaeozoic discinids [PDF]

open access: yesActa Palaeontologica Polonica
The discinid brachiopod from the Lower Triassic Osawa Formation in the Southern Kitakami Terrane, Japan, exhibited a unique morphological combination of a narrow pedicle track (listrium) and a V-shaped large depressed area, thereby suggesting an ...

Modelling Palaeodistributions in Marine Environments: A Review

open access: yesJournal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim This scoping review (ScR) synthesises the current literature on the application of Species Distribution Models (SDM) to past marine environments. We assess how these models have been used to reconstruct past environmental suitability, track biogeographical shifts and investigate long‐term ecological dynamics, while identifying key ...

Orientation of Telotrematous Brachiopoda [PDF]

open access: yesNature, 1953
A STUDY of the development of the rhynchonellid, Tegulorhynchia nigricans, Sowerby, shows the larva to be furnished with two pairs of large tufts of long setae set on the hind margin of the mantle rudiment. The members of one pair lie dorso-laterally, those of the other pair laterally.

The Permian–Triassic transition in Türkiye: New insights and 3D outcrop models for accessible, reproducible and sustainable fieldwork

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
We studied the Permian–Triassic successions of south‐western Türkiye at five locations, synthesised sedimentological and palaeontological data, putting it into a consistent stratigraphic framework and incorporating 3D digital outcrop models. Abstract The Permian–Triassic transition is characterised by major environmental changes and the largest known ...

First record of the Ordovician fauna in Mila-Kuh, eastern Alborz, northern Iran [PDF]

open access: yesEstonian Journal of Earth Sciences, 2015
Restudy of the Cambrian–Ordovician boundary beds, traditionally assigned to the Mila Formation Member 5 in Mila-Kuh, northern Iran, for the first time provides convincing evidence of the Early Ordovician (Tremadocian) age of the uppermost part of the ...

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

open access: yesAustral 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

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.
