Study: Dolphins Once Behaved Like Killer Whales
A STUDY HAS FOUND THAT AN EXTINCT GIANT DOLPHIN BEHAVED LIKE KILLER WHALES DO TODAY
(CNN) – Dolphins may have had a more ferocious past than previously known.
New research has found that an ancient dolphin the lived about 30 million years ago was similar to the current-day killer whale.
They were the apex predators of the ocean, using echolocation to “see” through sound underwater.
The study, published in the journal Current Biology says the specimen was discovered partly in rock formations in South Carolina.
This ancient dolphin had a 15-foot long body size, a shorter and stronger snout.
It’s tooth wear and vertebral formation indicated it could eat both small and large-bodied pray and swim faster than other whales.
