Annelid Borings on Brachiopod Shells From the Upper Ordovician of Peru. A Long-Distance Co-migration of Biotic Partners

open access: yesFrontiers in Ecology and Evolution, 2021
The Recent planktonic larvae of the polychaete spionids are some of the most widespread and abundant group of coastal meroplankton worldwide. To study the possible co-migration of biotic partners and determine whether they were host-specific, the type of

Geological Revolutions in the Late 20th and Early 21st Centuries: Plate Tectonics, Extraterrestrial Impacts, and Snowball Earth

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT During the late 20th and early 21st century three conceptual revolutions reordered our understanding of the history of the Earth: The spread of plate tectonic theory from the 1960s onward which brought geology the first meaningful theory for building mountains and the migration of continents; the rebirth of catastrophism in 1980 with the ...

The genus Coryphodon in Europe: contribution of new exceptional material from Le Quesnoy (northern France, early Eocene, MP7)

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Pantodonts are an extinct group of herbivorous eutherian mammals. They comprise 8 families and 23 genera, ranging from the early Paleocene to the late Eocene, including Bemalambda, Barylambda, Titanoides, or Pantolambda. In Europe, only one genus is known, Coryphodon, represented by three species: C. eocaenus, C. anthracoideus and C.

A remarkable radiolarian assemblage from the Csővár area (Hungary) improves biostratigraphical correlation of the Rhaetian

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract In the Csővár area of north‐central Hungary a remarkably well‐preserved Rhaetian radiolarian fauna, in which conodonts were also found, has enabled the identification of 49 radiolarian species belonging to 35 genera. The fauna is dominated by the orders Spumellaria and Entactinaria over less diverse Nassellaria.

Incorporating Fossil Data Into Ecological Niche Models Enhances Predictions of the Past Distribution of Macaronesian‐Mediterranean Strawberry Trees

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We demonstrate that fossil‐informed SDMs not only improve spatial accuracy and ecological realism in past projections, but also provide an external form of validation that traditional hindcasts often lack. ABSTRACT Hindcasting is a widely used method to predict the past distribution of plant species. However, its reliability is often constrained by the

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.

Callovian–Oxfordian hecticoceratins from western India: Their biostratigraphic and palaeobiogeographic implications

open access: yesJournal of Palaeogeography, 2014
The Kutch Basin of western India is famous for its rich assemblages of the Callovian–Oxfordian ammonites. The family Oppelidae Douvillé is the second most diverse ammonite group after perisphinctids during the Middle–Upper Jurassic.

Affinity in Concentric Circles (ACC): A Geometric Representation of Dendrogram and Interpretation

open access: yesJournal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim We introduce “Affinity in Concentric Circles” (ACC), a method that converts dendrograms to a geometric form using similarity scores to compare dendrograms and identify affinity change patterns. Location China for trilobites and global for nisusiid brachiopods.

NEW INSIGHTS ON PALUDOTONA, AN INSULAR ENDEMIC LAGOMORPH (MAMMALIA) FROM THE TUSCO-SARDINIAN PALAEOBIOPROVINCE (ITALY, TUROLIAN, LATE MIOCENE)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
The first vertebrate genus described from the Baccinello-Cinigiano Basin, Paludotona, is here revised almost 6 decades after its original description, with the inclusion of new material. Paludotona is an endemic insular lagomorph that inhabited the Tusco-

open access: yesActa Palaeontologica Polonica, 2016
The eoorthid brachiopod Apheoorthina is reported for the first time from the Lower Ordovician of NW Argentina. It is represented by a species similar to A.
