Modern Tech Reveals Secrets of 250M-Year-Old 'Elgin Marvel' Fossil

Researchers have used high-resolution 3D imaging to study the brain cavity of Gordonia, a pig-like protomammal from the Permian Period, revealing early signs of mammalian brain evolution. Despite its reptilian brain structure, Gordonia's relatively large brain size hints at the intelligence that would later characterize mammals. The study, published in the Zoological Journal of the Linnean Society, provides insights into the evolutionary roots of modern mammalian brains.
