Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe 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 ...
