An enormous prehistoric snake longer than a college bus slithered round what’s now India 47 million years in the past, in line with new analysis.
The extinct snake might have been one of many largest to have ever lived, dwarfing present-day anacondas and pythons that may develop to about 6 meters (20 toes). The colossal creature’s scientific title is Vasuki indicus, after the legendary serpent across the neck of Hindu deity Lord Shiva and the nation of its discovery.
The snake was possible a slow-moving, ambush predator that subdued its prey by constriction or squeezing them to demise, in line with the examine, which appeared Thursday within the journal Scientific Reports.
The report’s two authors, primarily based on the Indian Institute of Technology Roorkee within the state of Uttarakhand, analyzed 27 fossilized vertebrae — some nonetheless related to 1 one other — that have been uncovered in 2005 at a coal mine in western India’s Gujarat state.
Initially, the group thought the bones belonged to an historic crocodile-like creature. It wasn’t till the researchers eliminated sediment from the fossils through the examine’s preliminary stage in 2023 that they realized they “were looking at the remains of an exceptionally large snake,” the authors mentioned.
The vertebrae appeared to belong to a completely grown animal, the examine mentioned.
“There are a number of possible reasons for its large size which range from favourable environment with ample food resources to lack of natural predators,” coauthors Debajit Datta, a postdoctoral fellow, and Sunil Bajpai, a professor of paleontology, mentioned in a joint e-mail.
“Another driving force could be the prevalence of warmer climatic conditions than at present,” they mentioned.
Based on the dimensions of the preserved vertebrae, the researchers estimated that the snake would have been 10.9 meters (36 toes) to fifteen.2 meters (50 toes) in size, primarily based on two completely different calculation strategies, with a broad and cylindrical physique.

A panoramic view of Panandhro Lignite Mine, in western India’s Gujarat state, reveals the fossiliferous stage (crimson arrow) the place the large snake Vasuki indicus was discovered.
Debajit and Bajpai mentioned they consider it lived on land moderately than water, like an anaconda, nevertheless it was unlikely to have frolicked in timber on account of its measurement.
The authors mentioned that the physique size estimates “should be treated with caution” as a result of they didn’t have an entire skeleton. However, the snake would have rivaled the biggest identified snake species — the extinct Titanoboa — in measurement.
Identified from fossils in Colombia, Titanoboa would have weighed 1,140 kilograms (2,500 kilos) and measured 13 meters (42.7 toes) from nostril to tail tip.
Snake measurement and the position of local weather
Snakes are cold-blooded and want warmth from the atmosphere to outlive. Their measurement, due to this fact, is determined by how heat the local weather is.
“Their internal body temperature fluctuates with the ambient temperature of the environment,” the authors mentioned. “So, higher ambient temperatures would have increased the internal body temperature and metabolic rate of Vasuki which in turn would have allowed it to grow so large.”
The group was capable of infer, primarily based on info on the dimensions and metabolism of residing snakes and present temperatures, that Vasuki lived in a heat, tropical local weather, with a imply annual temperature of 28 levels Celsius (82 levels Fahrenheit).
Datta and Bajpai mentioned the snake lived in a coastal marsh and swamp.
“We cannot say precisely what sort of animals Vasuki ate,” they mentioned. “Associated fossils collected from the rocks that yielded Vasuki include ray fish, bony fish (catfish), turtles, crocodilians and even primitive whales. Vasuki may have preyed upon some of these.”
