This image provided by researchers in April 2024 shows views of some of the vertebrae of Vasuki indicus, a newly discovered extinct snake from about 47 million years ago, estimated to reach nearly 50 feet (15 meters) long. The scale bar at the center of each row showing rotated views of an individual vertebra indicates 5 centimeters (almost 2 inches). (Sunil Bajpai, Debajit Datta, Poonam Verma via AP)
