UPPER SPATHIAN TO BITHYNIAN (LOWER TO MIDDLE TRIASSIC) BRACHIOPODS FROM NORTH DOBROGEA (ROMANIA)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
Brachiopods obtained from several Triassic localities in North Dobrogea, in Romania, are described. Upper Spathian and Aegean Hallstatt-type red limestones have been sampled in the Deşli Caira section, proposed as the GSSP for the base of the Anisian ...

Two new species of Waiparaconus (Octocorallia) of the enigmatic Family Waiparaconidae

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Waiparaconus, a Late Cretaceous to early Cenozoic fossil, was long interpreted as a pedunculate cirripede, but is now tentatively placed in the Pennatuloidea (Order Scleralcyonacea, Class Octocorallia). New material from the Snow Hill Island Formation (lower Maastrichtian) at Vega Island, Antarctica is described and specimens from the Gingin ...

Stratigraphic significance of Devonian brachiopods of the Urals

open access: yesЛитосфера, 2017
The article considers the history of the formation of the regional stratigraphic scale of the Devonian system of the Urals, historically developed on the basis of the study of benthic fauna (mainly brachiopods).

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.

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1188-1212, July 2026.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1213-1242, July 2026.
Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

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 ...
