Titanoboa
about 58 million years ago in the jungle of South America there was a monster - the serpent, which reaches about 14 meters long and weighed more than a ton!
This giant reptile titanoboa could swallow a whole crocodile and, of course, can easily cope with a smaller prey. The snake was not poisonous, prey or enemy, she squeezed his body with such force that the victim had no chance vyzhit.
It is believed that titanoboa able to achieve larger than its modern relatives, primarily due to the warmer climate that existed at the time in the world. However, some scientists believe that since ancient snake was huge, it produced a lot of metabolic heat. So, the ambient temperature should be cooler at 4-6 ° C, than the current temperature of the Earth, or titanoboa simply be overheated.
After the extinction of the dinosaurs titanoboa was the largest predator on the planet for 10 million years. Today it is considered the largest snake ever existed on Earth. For comparison, the longest snake living now - reticulated python - reaches about 9 meters in length, and the most difficult - anaconda - can weigh 97 kg 5.
