An exceptionally preserved, mummified reptile dating back 289 million years is revolutionizing our understanding of how terrestrial animals first adapted to breathing on land. This diminutive creature, identified as Captorhinus aguti, showcases the earliest documented instance of the rib-cage-driven respiratory mechanism. This evolutionary leap, essential for vertebrates to successfully colonize land environments, is still employed by modern reptiles, birds, and mammals.
