S
u name e: Titanoboa cerrejonensis . The size of the vertebrae suggests that going on around 1,140 kilograms measuring 13 meters long and about one meter high. Was classified within the group of non-venomous boa constrictors. Lived more or less 60 million years .

E l fossil was found in the Cerrejon coal mine in northern Colombia. and researchers focused on how it could have been the environment the snake when she was alive. There is a correlation between temperature and size of cold-blooded creatures. Thus, with increasing global temperature increases the maximum size of these creatures. By calculations, concluded that a snake the size of T. cerrejonensis would require an average annual temperature of 30 to 34 ยบ C to survive.

you L tropical ecosystems of South America were strikingly different 60 million years ago. The land was a jungle, even warmer than today, and reptiles that lived were much larger. As a result, among other things, there existed the largest snakes of which there is knowledge.
