Paleontologists in Peru on Monday unveiled the 9-million-year-old fossil of a relative of the great white shark that once inhabited the waters of the southern Pacific Ocean, where it liked to devour sardines.



The nearly-complete Cosmopolitodus Hastalis fossil was found some 235 km south of Lima in Peru's Pisco basin, a hot, desert area famed for frequent discoveries of ancient marine species.



The shark is believed to be an ancestor of the great white shark. It is now extinct, but its teeth once spanned up to 8.9 cm in length, while adults could grow to near seven meters in length - the size of a small boat.



Cesar Augusto Chacaltana, an engineer at the Peruvian geological and mining institute (INGEMMET), said at a presentation the shark's remains showed "exceptional fossilization."



Researchers presented the ancient shark's remains in several glass urns, including one containing a giant, sharp-toothed jaw.



"There are not many complete shark (fossils) in the world," paleontologist Mario Urbina added at the presentation, adding the remains of numerous sardines were found inside the stomach.
