Pliosaur (Vengeance from the Deep #1)

Archeologist John Paxton has always been eluded by the great find. But his luck is about to change on a mysterious island near South Africa, where he seeks a rare prehistoric fish. Deep inside the caves, John finds more than he bargained for. He encounters the tribal elder, Kota―practically the devil himself with a plan straight from hell. Within the caverns beneath the island, the tribe worships and nurtures a prehistoric marine reptile that could engulf T-Rex. The size of a sperm whale, and equipped with ten-foot jaws bristling with eighteen-inch teeth, this pliosaur is the last remaining member of the greatest predator species that ever lived. Only then does John realize Kota’s true agenda―to unleash the leviathan on the modern world to fulfill the tribe’s bloodlust for revenge. Now it’s all up to John to warn humanity of the fifty-ton killing machine headed its way―before the Ivory Coast washes blood red. But first, he has to get off the island . . . alive.
