1. What Was the Largest Snake Ever Found?
The title of the largest snake ever found has been a subject of scientific debate. For many years, Titanoboa cerrejonensis held the crown. However, recent discoveries suggest a new contender. Let’s delve into the details of both species.
1.1. Titanoboa Cerrejonensis
Described in 2009, Titanoboa cerrejonensis was believed to be the largest snake to have ever existed. It lived approximately 60–58 million years ago in what is now Colombia. Its name, “Titanoboa,” reflects its gigantic size, and “cerrejonensis” refers to the Cerrejón Formation in Colombia, where its fossils were discovered.
1.1.1. Size and Weight
The fossil backbones, or vertebrae, of Titanoboa are enormous, measuring over 11 centimeters wide. By comparing these vertebrae with those of modern-day relatives like boas, scientists estimated that Titanoboa grew to around 13 meters (42.7 feet) long and weighed about 1,135 kilograms (2,500 pounds). This makes Titanoboa approximately three meters longer and five times heavier than any snake species living today.
1.1.2. Habitat and Environment
The size of Titanoboa has led researchers to speculate about its prehistoric environment. Some scientists suggest that it lived in areas with temperatures reaching 30–34°C (86–93°F). This estimate, however, is debated, with other calculations predicting a cooler climate. The warm environment likely supported its massive size, allowing it to thrive in the tropical ecosystem.
1.1.3. Skull Material
Some skull material believed to belong to Titanoboa has also been found. However, as of the latest reports, scientists have not yet published a detailed description of these findings. The skull could provide additional insights into its feeding habits and evolutionary relationships.
1.2. Vasuki Indicus
In 2024, scientists announced the discovery of another record-breaking fossil snake named Vasuki indicus. This snake was found in western India and lived around 47 million years ago. Its name, “Vasuki,” is derived from a mythical snake associated with the Hindu deity Shiva, and “indicus” signifies its discovery in India.
1.2.1. Size Estimates
Vasuki indicus is estimated to have been between 11–15 meters (36–49 feet) long. This means it could potentially be longer than Titanoboa. However, researchers have urged caution in officially declaring Vasuki indicus as the longest snake ever found. The primary reason for this caution is the differences in the methods used to calculate the total length of the two snakes.
1.2.2. Classification
Unlike Titanoboa, which is related to boas, Vasuki indicus may have belonged to an extinct family called Madtsoiidae. This family of snakes is known from fossils found in various parts of the world, including South America, Africa, and Australia. Understanding its classification helps scientists piece together the evolutionary history of snakes.
1.2.3. Implications of the Finding
The discovery of Vasuki indicus challenges previous assumptions about the maximum size that snakes can achieve. It also suggests that the Madtsoiidae family may have been more diverse and widespread than previously thought. Further research and analysis will be needed to confirm its exact size and place in the snake family tree.
