science π¦ Ancient reptile fossil shows early water life
Chinese scientists discovered a 244-million-year-old reptile fossil named Austronaga in Yunnan province. This specimen represents the earliest known archosauromorph highly adapted for aquatic life, challenging previous assumptions about their terrestrial existence. The study, led by Li Chun, was published in Science Advances on August 11, 2026. Detailed features like flipper-like limbs and preserved stomach contents confirm its fully aquatic predatory lifestyle. This finding significantly updates the timeline of reptile adaptation post-mass extinction. π
