Cómo un fósil de millones de años ayuda a entender por qué algunos animales marinos flotan más que otros

Researchers at the University of Oslo have analyzed ancient fossils to better understand the buoyancy mechanisms of prehistoric marine animals. The study reveals that the ribs of ichthyosaurs, a type of marine reptile, were significantly more compact and heavier than previously believed.

This physiological trait likely served a mechanical purpose, helping the creatures regulate their buoyancy and initiate deep dives into the ocean. The findings shed light on the physical adaptations that allowed these ancient marine reptiles to navigate their underwater environments.
