Agglutinated Foraminiferal Acmes and Their Role in the Biostratigraphy of the Campanian–Eocene Outer Carpathians

Geosciences, 2021
The biostratigraphy of the Outer Carpathians is based mainly on the ranges of agglutinated foraminifera. Species acmes provide the opportunity to enhance and support the existing biozonations.

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua

The Anatomical Record, EarlyView.
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

The Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Bilateral Supracondylar Process in a Subadult in the Late Antique Age: A Case Report

Archaeometry, EarlyView.
ABSTRACT During the excavation procedures for the railway trait Napoli‐Cancello, in the city of Afragola (Naples), several burials dating back to the Late Antique Age were found. One of them was an amphora burial (enchytrismòs) and contained the skeletal remains of a subadult individual affected by bilateral supracondylar process. Supracondylar process
