The Spanish Oceanography Institute, or IEO, discovered in waters of the Canary Islands a large deposit of fossils of the largest marine predator that ever existed, the megalodon, a shark that became extinct 2 million years ago.
The deposit was found at the foot of an undersea mountain some 2,000 meters (6,500 feet) deep during an ocean research campaign, the IEO said Monday in a communique.
Those responsible for the discovery call this "an event of great scientific significance."
These fossils "show that the biggest marine predator of all time lived, hunted and reproduced in these waters during that era," a shark that grew to be 20 meters (65 feet) long and weigh 100 tons.
For the kind of teeth it possessed, scientists think it fed on large prey like whales, dolphins, seals and other marine mammals, as well as on large fish and turtles.
It was a great migrator found in every ocean, according to the IEO.
The discovery of its remains in the Canaries occurred in October 2012, when the IEO research vessel Angeles Alvariño found a deposit of fossils of other extinct shark species, whales and a mammal of the Sirenia order, which covers marine species like manatees and dugongs.
Scientists finally determined that some of the fossils found were the remains of a megalodon.
