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 ...

Understanding the Form and Timing of Damage to Archaeological Sites During the Syrian Conflict by Combining Evidence From Remote Sensing With Ground Observation

Archaeological Prospection, EarlyView.
ABSTRACT Satellite remote sensing is used widely to monitor damage to archaeological sites in conflict areas, including in Syria. On‐the‐ground assessments have been fewer in number, and the degree to which remote sensing assessments reflect what is happening on the ground has not been extensively tested.
