De Geer Land Bridge

From Wikipedia, the free encyclopedia

The De Geer Land Bridge was a land bridge that connected Fennoscandia to northern Greenland.[1] The land bridge provided a northern route from Europe to North America from the Late Cretaceous to the Early Paleocene,[1] although this timeframe has been disputed.[1]

The De Geer Land Bridge provided a path from Scandinavia across the Barents Sea to Svalbard, northern Greenland, and northern Canada.[1] This may have been possible due to the Barents Sea residing on the shallow continental shelf.

Relation to other land bridges

[edit]

The De Geer Land Bridge was the initial route from Europe and North America. Long after the De Geer Land Bridge disappeared, the Thule Land Bridge appeared and offered a more southern route from Europe to North America.[1]

Beringia, a land bridge from Northeast Asia to Alaska, was another route to North America that existed at the same time as the De Geer Land Bridge.[1]
