This ancient Indian serpent rivalled Titanoboa in size
India's Vasuki indicus, identified in 2024 from fossils discovered in Gujarat, is among the longest snakes ever known, rivaling the legendary Titanoboa. The prehistoric giant offers fresh insights into ancient snake evolution and highlights India as a key centre of prehistoric biodiversity.

Today, nearly 3,000 species of snakes are found across the world. Some are highly venomous, while others are completely harmless. Some are tiny enough to fit in the palm of your hand, while others grow to astonishing lengths.
When it comes to the world's biggest snakes, a few names immediately come to mind. Green anacondas can grow 15 to 20 feet long, reticulated pythons can exceed 20 feet, and even the mighty king cobra can reach 13 feet. Impressive as these giants are, they are dwarfed by one prehistoric serpent that has long held the title of the world's largest snake: Titanoboa.
For years, Titanoboa cerrejonensis, estimated to have reached 48 to 50 feet (14.6–15.2 metres) in length, has been regarded as the undisputed giant of the snake world.
However, in 2024, India made a remarkable contribution to palaeontology with the identification of Vasuki indicus, an ancient snake species that ranks among the longest ever known.
Estimated to have reached an astonishing 15 metres (49 feet) in length, and this prehistoric giant lived around 47 million years ago during the Middle Eocene Epoch.
DISCOVERED IN 2004, MYSTERY SOLVED TWO DECADES LATER
Although Vasuki indicus made global headlines in 2024, its story actually began two decades earlier.
The fossil remains were first unearthed in 2004 from the Panandhro Lignite Mine in Gujarat, offering scientists an important glimpse into India's prehistoric ecosystems. However, the fossils remained unidentified for nearly 20 years before researchers formally described them as a new genus in 2024.
Named after Vasuki, the mythical serpent from Hindu mythology, Vasuki indicus belonged to the now-extinct Madtsoiidae family, a lineage of large, non-venomous constrictor snakes. Its discovery places it among the longest snake species ever identified, making it one of Titanoboa's closest rivals in terms of size.
What made Vasuki indicus so enormous?
According to a study published in Scientific Reports, the snake's skeletal structure suggests it was a slow-moving ambush predator, much like modern pythons and anacondas. Given its enormous size, researchers believe it would have had very few natural predators.
The fossilised vertebrae provide remarkable clues about its body size. Each vertebra measures between 37.5 and 62.7 millimetres (1.48–2.47 inches) in length and 62.4 and 111.4 millimetres (2.46–4.39 inches) in width, indicating a thick, cylindrical body.
Based on these measurements, researchers estimate that Vasuki indicus measured between 10.9 and 15.2 metres (35.8–49.9 feet) in total length.
That places Vasuki indicus in the same size range as Titanoboa, the largest snake ever discovered, although scientists note that there is still some uncertainty surrounding these estimates.
Given its massive build, the snake was likely slow-moving and relied on ambush tactics similar to those of modern anacondas, according to ScienceDaily.com.
A SURVIVOR FROM AN ANCIENT SNAKE FAMILY
Researchers classify Vasuki indicus within the Madtsoiidae family, an extinct lineage of snakes that survived for nearly 100 million years, from the Late Cretaceous to the Late Pleistocene. Members of this family lived across a vast geographic range that included Africa, Europe, South America and India.
The study further suggests that Vasuki indicus may belong to a lineage of giant madtsoiid snakes that first evolved in India.
Titanoboa vs Vasuki indicus: How do the prehistoric giants compare?
| Feature | Titanoboa cerrejonensis | Vasuki indicus |
|---|---|---|
| Discovered in | Cerrejƒón coal mines, Colombia | Panandhro Lignite Mine, Gujarat, India |
| Lived during | Paleocene Epoch (58–60 million years ago) | Middle Eocene Epoch (47 million years ago) |
| Estimated length | 12.8–15.2 metres (42–50 feet) | 10.9–15.2 metres (35.8–49.9 feet) |
| Estimated weight | 1.1–1.25 tonnes | Around 1 tonne |
| Family | Boidae (relatives of boas and anacondas) | Madtsoiidae (extinct snake family) |
| Habitat | Tropical rainforests; largely semi-aquatic | Coastal swamps; likely terrestrial |
| Hunting style | Apex predator; believed to have fed mainly on fish | Slow-moving ambush predator; likely preyed on crocodilians and other large vertebrates |
MORE THAN JUST ANOTHER GIANT SNAKE
The discovery of Vasuki indicus is significant not simply because it was enormous, but because it expands scientists' understanding of prehistoric life on the Indian subcontinent.
It suggests that India was home to some of the largest snakes ever to exist and may even have been an evolutionary centre for giant madtsoiid snakes.
While Titanoboa continues to hold the record as the largest known snake based on current evidence, Vasuki indicus has firmly established itself among the greatest serpents in Earth's history.
Hidden beneath the rocks of Gujarat for millions of years, this prehistoric giant is now helping researchers piece together a fascinating chapter of India's ancient past; one vertebra at a time.
