Facile (Z)‐Selective Synthesis of β,γ‐Unsaturated Ketones by a Silicon‐based Olefination Strategy
Angewandte Chemie International Edition, EarlyView.A silicon‐based olefination strategy has been developed to access challenging (Z)‐configured β,γ‐unsaturated ketones from readily accessible branched vinyl silanes and acid chlorides. This method enables the straightforward synthesis of a broad variety of deconjugated ketones with high (Z)‐selectivity under mild conditions and provides a new ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
The Anatomical Record, EarlyView.Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Morphology and function of pinniped necks: The long and short of it
The Anatomical Record, EarlyView.Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

The Anatomical Record, EarlyView.Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

The Anatomical Record, EarlyView.Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated
