Silurian Erosion

440 to 410 million years ago

The Silurian Period was a time of erosion on the uplifted Ozarks dome. No Silurian rocks are present in the Ozarks area. Rivers and streams were 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 Ozarks area was still in the tropics south of the equator.
