February 4, 2009--The biggest snake yet discovered, Titanoboa cerrejones, slithers alongside one of its presumed prey, a primitive crocodile, 60 million years ago in an artist's conception..

At least 42 feet (13 meters) long and weighing 2,500 pounds (1,135 kilograms), the snake was "longer than a city bus ... and heavier than a car," said University of Toronto Mississauga biologist Jason Head, who announced the find today

Found in a Colombian coal mine, a vertebra from a 45-foot (14-meter) Titanoboa cerrejones dwarfs a similar bone from a 17-foot (5.2-meter) anaconda--currently the world's biggest, if not longest, snake species.

The ancient snake's giant size suggests that mean year-round temperatures in the tropics were several degrees warmer than they are today, according to a study that analyzed the relationships among a snake's body size, its metabolism, and the outside temperature.

"We were able to use the snake, if you will, as a giant fossil thermometer," said biologist Jason Head, lead author of the new study, to be published February 5, 2009, in the journal Nature.

Kathleen, a 14-foot (4.3-meter), 90-pound (40-kilogram) anaconda, is examined at the New England Aquarium in Boston in 2007.

Giant, or green, anacondas are the largest snakes in the world today. At about 300 pounds (136 kilograms), though, a modern anaconda would have been no rival for a 2,500-pound (1,135-kilogram) Titanoboa cerrejones, the newfound prehistoric snake announced in February 2009.

Like an anaconda, Titanoboa was a constrictor, and considering its size, the snake's crushing grip "would be probably like one of those devices they use to crush old cars in a junkyard," said Hans-Dieter Sues of the National Museum of Natural History in Washington, D.C.

n an undated photo, an Indonesian family holds their pet reticulated python--probably the longest living snake species at a maximum of more than 30 feet (9 meters).

By contrast, Titanoboa cerrejonesis measured at least 42 feet (13 meters), according to a February 2009 study. The newfound, 60-million-year-old snake species' giant size was driven by the warmer temperatures of its era.

So could Titanoboa-size snakes return with global warming? "Maybe," study co-author Jonathan Bloch said. "They definitely could, or maybe ... the warming could happen so rapidly that [snakes] wouldn't have time to adapt."
