A brand new genus and species of large madtsoiid snake that lived in what’s now India round 47 million years in the past (early Middle Eocene epoch) has been recognized from a partial vertebral column unearthed within the Indian state of Gujarat.

Scientifically named Vasuki indicus, the brand new species thrived throughout a heat geological interval with common temperatures estimated at 28 levels Celsius.
The historical snake was a part of Madtsoiidae, an extinct group of primarily Gondwanan land snakes with a temporal vary spanning about 100 million years from the Late Cretaceous epoch to the Late Pleistocene.
“The Madtsoiidae family existed for around 100 million years from the Late Cretaceous to the Late Pleistocene and lived in a broad geographical range including Africa, Europe, and India,” mentioned Indian Institute of Technology Roorkee paleontologists Debajit Datta and Sunil Bajpai.
“Vasuki indicus represents a lineage of large madtsoiids that originated in the Indian subcontinent and spread via southern Europe to Africa during the Eocene, approximately 56 to 34 million years ago.”

A sequence of 27 largely well-preserved vertebrae from a fully-grown Vasuki indicus was recovered from the Panandhro Lignite Mine, which is a part of the Naredi Formation within the Gujarat state, western India.
The vertebrae measure between 3.75 and 6.3 cm (1.5-2.5 inches) in size and 6.24 and 11.14 cm (2.5-4.4 inches) in width, suggesting a broad, cylindrical physique.
Vasuki indicus reached an estimated size of between 11 and 15 m (36-49 toes), making this species the biggest recognized madtsoiid snake.
“This is comparable in size to the longest known snake to have ever lived, the extinct Titanoboa,” the researchers mentioned.
“The large size of Vasuki indicus made it a slow-moving, ambush predator akin to an anaconda.”
“Biogeographic considerations, seen in conjunction with its inter-relationship with other Indian and North African madtsoiids, suggest that Vasuki indicus represents a relic lineage that originated in India,” they added.
“Subsequent India-Asia collision at 50 million years ago led to intercontinental dispersal of this lineage from the subcontinent into North Africa through southern Eurasia.”
“Recovery of additional material and new species, including large-sized forms, may provide further insights into madtsoiid systematics and biogeography.”
The examine was printed within the journal Scientific Reports.
