A Mesozoic bird from Gondwana preserving feathers

Nature Communications, 2015
The fossil record of birds in the Mesozoic of Gondwana is mostly based on isolated and often poorly preserved specimens, none of which has preserved details on feather anatomy.

Phylogeny and divergence times of the African and Malagasy Podocarpus (Podocarpaceae) and their taxonomic and biogeographic implications

TAXON, EarlyView.
Abstract Podocarpus is the most speciose genus of the podocarp family (Podocarpaceae) widely distributed in the mountain forests of subtropical and tropical Asia, the Neotropics and Australasia, where its members have been shown to have had multiple origins.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

Insect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

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

Methods 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 ...

Relationship and Source of Whitings Used as a Painting Ground in Icons From Polish Museum Collections Based on Their Calcareous Nannofossil Content

Archaeometry, EarlyView.
ABSTRACT In icon painting, chalk whiting is key to creating a gesso ground, providing a smooth, absorbent surface for paint. Calcareous nannofossils, tiny marine skeletons found in chalk, are an ideal tool for analyzing the origin of an icon's chalk ground, often the only reliable information about where the icon came from.
