Devonian Erosion

410 to 360 million years ago

The Devonian Period was a time of continued erosion on the uplifted Ozarks dome. No Devonian rocks are present in the central Ozarks area. Devonian sediments are present around the edges of the Ozarks dome. Rivers and streams continued eroding away the top part of the thick sequence of sediments made during the Ordovician time.

In the northeast, mountain building continued in New England as central Europe and Scandinavia collided with Greenland and northeastern North America.

The Ozark area was still in the tropics south of the equator.
