Previously unknown species of dolphin swam the oceans 20 million years ago, including in waters that covered Switzerland, today a landlocked country at the heart of Europe, researchers said Tuesday.
Back then, Switzerland was part of an island landscape, with its low-lying parts covered in ocean teeming with fish, sharks and dolphins, and with mussels and sea urchins lining the seabed.
After examining around 300 fossils of whales and dolphins found in Switzerland and dating from this period, researchers from Zurich University's paleontological institute discovered two previously unknown species, the university said in a statement.
