Nature Podcast ‘Stealth flippers’ helped this extinct mega-predator stalk its prey
Jul 16, 2025
Johan Lindgren, a scientist from Lund University, shares insights about the ancient mega-predator Temnodontosaurus, revealing its stealth adaptations through a unique fossil flipper. Gerrit Miesenbach from Oxford discusses a study linking mitochondrial damage during wakefulness to the need for sleep. Lizzie Gibney, a reporter, highlights how researchers are using AI to manipulate peer review processes in academia, raising ethical concerns. The podcast blends paleontology, biology, and the implications of technology in research, making for a fascinating listen.

Episode notes
Stealthy Flippers in Temnodontosaurus
- Temnodontosaurus had flippers with serrated edges likely reducing low-frequency noise.
- This adaptation suggests it hunted stealthily using its large eyes in dark waters.
Noise Reduction Confirmed by Simulation
- Hydroacoustic simulations showed the serrated flipper edges dampened low-frequency swimming noise.
- This noise reduction likely helped Temnodontosaurus approach prey quietly underwater.
Stealth Adaptation Facilitated Hunting
- Temnodontosaurus likely preyed on squid-like cephalopods sensitive to low-frequency sound.
- Its stealth adaptations helped it hunt effectively by minimizing noise to avoid alerting prey.
