These animals include sharks in the waters that seldom rise to the surface except to find prey. Issues that spread, though this shark has never been found alive, many of the scientists argue that this shark is still alive, and including living fossils. Descendants of this shark is a shark near white.

Gigantopithecus lived in the mountains in China. Gigantopithecus lived in the late Tertiary period until the beginning of the Quaternary period. Gigantopithecus is estimated to have about 3 feet tall. Gigantopithecus eating bamboo and other plants.
Gigantopithecus was first discovered in 1935, when a German paleontologist who discovered the fossil tooth sold in Chinese drugstores. He knew that the teeth came from apes, which have not been identified. There is a theory that Gigantopithecus was still alive until now. Some people believe that this animal is a yeti or a snowman that he lived in the Himalayas.

4. Helicoprion

Helicoprion is a type of shark that lived about 300 years ago. In contrast to modern sharks, this shark has teeth circular saws are reminiscent of the round.

  6. Dunkleosteus

 Unlike sharks, which have survived for more than 400 million years old, has a short-term Dunkleosteus than 50 million years. They can reach sizes up to 30 feet long and weighing more than 4 tons.
Because the body that are naturally formed as layers of steel, these animals can be categorized as relatively slow-moving animal. These animals are considered only stayed at the bottom of the ocean.
In addition to the teeth, the front jaw of the animal is shaped like a very sharp beak. This animal is an animal that has the most powerful bite than Pliocene shark Megalodon.

8. Orthocone

 

About 460 years ago, orthocone is the largest animal on earth and is a predator that terganas existing. These animals live a very long conical shell (kira2 11 m). Without fins or tail.
Orthocone move by way of pushing water toward the opposite direction to the destination. Vertical movement is done by controlling the amount of sea water that is in the shell.
Food from these animals are some anthropoda, such as sea scorpion.
