Scientists find mysterious 250 million-year-old fossils that roamed the Earth before the ‘Great Dying’ extinction; to open doors to new discoveries

New research, based on fossils discovered in Tanzania and Zambia, broadens our understanding of the Permian ecosystem before the Great Dying. These finds, including saber-toothed gorgonopsians and burrowing dicynodonts, allow comparisons between different regions of Pangea. The studies reveal a shift to localized ecosystems after the extinction, potentially enabling the rise of new groups.
