Buried deep beneath the sediment of the North Atlantic Ocean lies an ancient, lost landscape with furrows cut by rivers and peaks that once belonged to mountains.
Geologists recently discovered this roughly 56-million-year-old landscape using data gathered for oil companies.
These results were publish in the journal Nature Geoscience. The data have revealed a landscape about 3,861 square miles (10,000 square km) west of the Orkney-Shetland Islands that stretched above sea level by almost as much as 0.6 miles (1 km). Researchers suspect it is part of a larger region that merged with what is now Scotland and may have extended toward Norway in a hot, prehuman world.
