biggest snake in the world

Some scientists in Colombia have found fossils of prehistoric monster that allegedly as the world's largest snake that ever lived on earth. Snakes Titanoboa named cerrejonensis weight was estimated to have more than 1 ton and the length to almost 14 meters.

Some scientists believe this snake lived on earth approximately 58 million to 60 million years ago. Geologist, David Polly, who estimated the size and weight of fossil Titanoboa based position.

"The size of the snake was really big. However, the research team was still thinking about how much heat the earth is needed to warm that big snake."

Titanoboa fossils discovered by a team of international scientists in a coal mine in tropical areas Cerrejón, Colombia. "Snakes are very big this really invites the imagination, but the fact that there have been beyond fantasy in Hollywood though," said paleontologist Jonathan Bloch, who was also involved in the expedition.

"Snakes are trying to annex Jennifer Lopez in the movie Anaconda was not for the snake that we found," said Bloch. Based on the size of the snake, Bloch explains, scientists can calculate the annual temperature average at the equator of South America 60 million years ago, reaching about 33 degrees Celsius, about 10 degrees warmer than today.

"Tropical Ecosystems of Latin America is much different now than 60 million years ago," said Bloch. "The condition of tropical forests is almost the same as today, but the temperature was warmer and filled with cold-blooded reptiles bigger."

According to Nature.com, the snake is the type of animal poikilotherms (cold blooded) that require heat from their environment to raise your metabolism crawling. Therefore, scientists estimate that the giant snakes live in tropical ecosystems of South America with temperatures at that time were not under 30 and 34 degrees Celsius.

Most of the current population of snakes found in tropical regions of South America and Southeast Asia. Temperatures in South America and southeast Asia allows animals to grow until they reach full size.
