Scientists Uncover Secrets of Ancient Dolphin Skull

Researchers have discovered a new prehistoric dolphin species, Romaleodelphis pollerspoecki, from 22 million years ago in present-day Austria. This species, identified from a fossil skull, shows early evidence of echolocation abilities similar to modern dolphins. The discovery provides insights into the evolution of toothed whales and their auditory capabilities. The study, published in the Journal of Vertebrate Paleontology, highlights the dolphin's advanced hearing, which may have aided in communication and predator evasion.
