Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Seagrass-associated Middle Miocene brachiopods from the Central Paratethys, with description of a new species of Bronnothyris

open access: yesActa Palaeontologica Polonica
The Middle Miocene brachiopod fauna of the Mecsek Hills (Southern Hungary) is poorly known. In this paper the brachiopods of a new fossil site discovered by private collectors on the outskirts of Mecsekpölöske village is described. The studied assemblage

Sedimentology and ichnology of Neogene Coastal Swamp deposits in the Niger Delta Basin, Nigeria

open access: yesGeologos, 2016
Often analyses of depositional environments from sparse data result in poor interpretation, especially in multipartite depositional settings such as the Niger Delta.

Inferring bird migration from bone isotopes and histology: A fossil‐friendly methodological framework

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Bird seasonal migration is a remarkable biogeographic phenomenon, yet its deep‐time origin(s) and evolutionary history remain poorly understood, with the bird fossil record largely overlooked. This study explores the predictability of bird migratory behaviour from the oxygen isotope composition of their bone apatite phosphate (δ18Op), a ...

U/Th Dating of Secondary Carbonate Deposits in Underground Galleries of Fourvière Hill (Lyon, France) Reveals a Water Supply System in Operation From the Roman Period to the Middle Ages

open access: yesArchaeometry, EarlyView.
ABSTRACT The recent discovery of a water draining structure known as the Antiquaille galleries in Fourvière hill, in the center of Lyon, France (ancient Lugdunum), sheds light on the water drainage system built by the former inhabitants of this area for their water needs.

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

open access: yesBoreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

First record of a fossil spittlebug (Hemiptera: Auchenorrhyncha: Aphrophoridae) in Miocene deposits in Bulgaria

open access: yesHistoria naturalis bulgarica
The first fossil record of a spittlebug affiliated to Aphrophora Germar, 1821 (Hemiptera: Cercopoidea: Aphrophoridae) is reported from Bulgaria (Western Rhodopes, Satovcha Graben).

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

open access: yesBoreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

open access: yesBoreas, EarlyView.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.
