Imagine standing in a dusty mine shaft, the afternoon sun filtering through a narrow opening, and suddenly realizing you’re about to glimpse a creature that once slithered through forests 47 million years ago. That’s exactly what happened to a team of paleontologists in Gujarat, India, when they uncovered a fossil that redefines our understanding of prehistoric giants. The discovery of Vasuki Indicus is sending ripples through the scientific community—and may well rewrite the record books for the largest snake ever known.

A remarkable find in Kutch’s ancient mines
I recall visiting a small museum near Ahmedabad where local guides proudly displayed ammonite shells and small dinosaur fragments, but I never expected to learn that the same region hides a monster from the Eocene epoch. In 2005, engineers working in a gypsum mine near Kutch stumbled upon a series of unusually large vertebrae embedded in rock. Intrigued, researchers from the Indian Institute of Technology (IIT) reexamined the site and carefully extracted 27 fossilized vertebrae—each as heavy as my old bicycle wheel and nearly perfectly preserved.
Dr. Rajesh Kumar, one of the lead scientists on the subsequent study (published on April 18, 2024, in Scientific Reports), described the specimen as “perfectly preserved,” emphasizing how rare it is to find such intact remains after tens of millions of years. For anyone who’s ever dug around for fossils in dusty fields, the notion of stumbling upon a prehistoric snake measuring over 10 meters is nothing short of a dream come true. Their meticulous work not only confirmed the specimen’s authenticity but also raised the exciting possibility that this find might eclipse Titanoboa—the colossal Colombian boa once thought to be the largest snake on record.
Vasuki Indicus: the largest snake of all time?
Named after Vasuki, the legendary serpent from Hindu mythology that coils around Shiva’s neck, Vasuki Indicus would have reigned supreme over its watery domain around 47 million years ago. By comparing the dimensions of its vertebrae to modern and extinct snakes, researchers estimate its length at anywhere from 10.9 meters to an astonishing 15.2 meters—easily surpassing the Titanoboa, which reached up to 14.3 meters. That means Vasuki Indicus might hold the title as the largest snake ever.
Several factors point to its immense stature. First, each vertebra is about twice as large as those from typical 5-meter-long snakes. Second, the curvature and shape of the bones suggest a robust, thick-bodied animal, not unlike the hefty boas and pythons we see today, but on a truly gargantuan scale. While Titanoboa thrived in the warm, swampy jungles of ancient Colombia some 60 million years ago, Vasuki Indicus made its home in what is now western India—a region that, during the Eocene, was teeming with lush wetlands and abundant prey.

Why was it so enormous?
In my own work as a wildlife volunteer, I’ve seen how modern anacondas grow fat and slow when they’re surrounded by plentiful food and few predators. Vasuki Indicus likely benefited from a similar ecological niche. The Eocene climate across the Indian subcontinent was warmer and more humid than today, creating favorable conditions for large reptiles. With ample prey—fish, small mammals, and perhaps even early primates—this snake could afford to bulk up without worrying about being chased by larger carnivores.
Dr. Kumar suggests three main reasons behind its colossal size: first, a resource-rich environment where food was plentiful; second, a lack of natural predators that would otherwise keep its growth in check; and third, the warmer global temperatures of the Eocene, which allowed cold-blooded animals to maintain higher metabolic rates. When I visited the IIT paleontology lab last year, the researchers showed me comparisons between Vasuki’s vertebrae and those of modern reticulated pythons—if you lined them up, it was as if someone had scaled today’s largest snakes by 1.5 times.
The discovery of Vasuki Indicus highlights India’s rich paleontological heritage, a fact underscored by the variety of prehistoric fossils unearthed in Kutch over the decades. Each new find offers a glimpse into a world where giants roamed freely, reminding us how much remains to be explored beneath our feet. As Dr. Kumar put it, “Every fossil tells a story of life long gone; Vasuki’s tale is one of nature’s most unbelievable chapters.”
