A team of paleontologists discovered a forgotten continent which is believed to be the land that helped mammals from Asia cross over to Europe approximately 34 million years ago.
The team of French, American and Turkish paleontologists and geologists led by the French National Center for Scientific Research (CNRS) researchers reassessed geological data relating to the Eocene region, which now belongs to the present-day Balkans, Europe and Anatolia, Turkey.
Their research suggested that the continent, which once sat among Europe, Asia and Africa, became the staging post for Asian mammals to migrate into Europe. The researchers have named the region Balkanatolia, according to the findings published in the March 2022 volume of Earth-Science Reviews.
“We know that, around 34 million years ago, Western Europe was colonized by Asian species, leading to a major renewal of vertebrate fauna and extinction of its endemic mammals, a sudden event called the ‘Grande Coupure,’” the CRNS said in a statement. “Surprisingly, fossils found in the Balkans point to the presence of Asian mammals in southern Europe long before the Grande Coupure, suggesting earlier colonization.”
The continent, which existed 50 million years ago, hosted “an endemic fauna that was very different from those of Europe and Asia,” according to the study.
The glacial geographical changes, which occurred some 34 million years ago, then connected Europe and Asia, giving rise to the “Grande Coupure” and subsequent colonization of the Asian mammals in Europe.
