Flinders University researchers have taken a revealing look inside the head of one of the first animals to crawl from the water to live on land more than 380 million years ago. Using high-tech neutron imaging, they scanned the skull and braincase of the only known specimen of Koharalepis jarviki, a large fossil fish found in freshwater rivers in the vast Lashly Mountains region of Antarctica which lived during the Devonian Period or "Age of Fishes."
