A high school student accidentally picked up a treasure dating to nearly 3 million years on the coast.
Biologist Ricardo Sagarminaga Van Buiten led Alnitak's expedition and found this giant white shark more than 5 meters long near Cabrera Island.
Although mysteriously extinct, they dominated the prehistoric ocean and became the terror of other sea monsters.
In a natural version of the Hollywood action movie, a great white shark was destroyed under the jaw of the larger fellow.
The 300 million-year fossil of a giant shark shows that they are nearly as long as a bus and much larger than today's white sharks.
