An Upper Cretaceous arthropod assemblage from Villaggio del Pescatore (Campanian, Italy) and its implications for peri‐Tethyan palaeobiogeography and palaeoecology

open access: yesPapers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The Villaggio del Pescatore (VdP) fossil Lagerstätte represents the most significant Upper Cretaceous (lower–middle Campanian) palaeontological locality in Italy and the Mediterranean region. We present the first systematic revision of the VdP fossil assemblage with a focus on its previously undescribed arthropod fauna, providing new insights ...

ppgm: an R package for integrating neontological, palaeontological, and climate data in a phylogenetic comparative framework

open access: yesPalaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Understanding how changes in climate affect habitat availability for species through time is critical for macroevolutionary, ecological, and conservation research. When combined with palaeoclimate reconstructions, the fossil record provides insights into how species' geographic distributions have responded to past climate shifts, including ...

Diferenciación genética de Merluccius gayi gayi y Merluccius gayi peruanus (Pisces, Merlucciidae) y antecedentes paleogeográficos de su área de distribución Genetic differentiation of Merluccius gayi gayi and Merluccius gayi peruanus (Pisces, Merlucciidae) and paleogeographic antecedent of their distribution area

open access: yesRevista Chilena de Historia Natural, 2000
Se han planteado variadas hipótesis sobre relaciones taxonómicas entre las especies de Merluccius, proponiéndose la existencia de dos subespecies Merluccuis gayi gayi y Merluccius gayi peruanus en el Pacífico Sureste; aunque hasta el momento no existen ...

Proteomic analysis resulting in species‐level identification of recently diverged North American arvicoline rodents

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1240-1251, October 2025.
ABSTRACT North American arvicoline rodents have long been considered to have high biogeographic, biochronologic, and paleoecological value. They provide relative dating of faunal assemblages when absolute dating is not possible and contribute to paleobiome characterization.

Multicostate zeillerids (Brachiopoda, Terebratulida) from the Lower Jurassic of the Eastern Subbetic (SE Spain) and their use in correlation and paleobiogeography [PDF]

open access: yes, 2012
The Lower Jurassic multicostate zeillerids of the Subbetic Domain are described here for the first time. A new species (Fimbriothyris? dubari) is erected, and the affinities of the remaining three species are discussed.

The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major
