The megalake holds the Guinness World Record for the largest known lake on Earth. It extended over an immense area of 2.8 million square kilometers, eclipsing even the vastness of the modern Mediterranean Sea. Within its confines, it harbored a remarkable reservoir of about 1.77 million cubic kilometers of water, a quantity exceeding the combined volume of all presently existing freshwater and saltwater lakes by more than tenfold.
