The world's largest snake (Titanoboa)

Some scientists in Colombia have found fossils of prehistoric monster that allegedly as the world's largest snake that ever lived on earth. Snake named Titanoboa cerrejonensis is estimated to have weighed more than 1 ton and up almost 14 feet long.

Some scientists believe this snake lived on earth some 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 huge. However, the research team was still thinking about how much heat is needed to warm the earth snake of that size. "Titanoboa fossil was discovered by an international team of scientists at a coal mine in the tropics Cerrejon, Colombia. "Snakes are very big this really inviting the imagination, but the fact that there has surpassed fantasy in Hollywood though," says paleontologist Jonathan Bloch, who was also involved in the expedition.

"The snake that tries to annex Jennifer Lopez in Anaconda movie is not as big snake that we found," said Bloch. Based on the size of the snake, Bloch explains, scientists can calculate the average annual temperature at the equator in South America 60 million last year reached about 33 degrees centigrade, about 10 degrees warmer than today."Tropical Ecosystems of Latin America is much different today than 60 million years ago," said Bloch. "The condition of tropical forests is almost the same as today, but the temperature is hotter then and filled with cold-blooded reptile is greater."

The snake is a type of animal poikilotherms (cold blooded), which require heat from their environment to generate creeping metabolism. Therefore, scientists estimate that the giant snakes live in tropical ecosystems of South America with temperatures at that time were not under 30 to 34 degrees centigrade.
Most of the current population of snakes found in tropical South America and Southeast Asia. Temperatures in South America and Southeast Asia allowed the animal to grow until reaching a large size.
