At its vastest, Paratethys had a surface area of more than a million square miles (2.8 million square km) – slightly larger than the present-day Mediterranean Sea, according to a team led by experts at Utrecht University, The Netherlands. For a modern day comparison, Paratethys would stretch from the eastern Alps to what is now Kazakhstan in central Asia (left). But it succumbed to cataclysms that turned the region into a ‘toxic waste-world’, killing off lifeforms including whales (top right), dolphins and seals. The researchers, who have detailed the megalake’s history in a new paper, based their estimations on geological and fossil records within the Black Sea (bottom right), where the Paratethys originally existed.
