The Devonian period was a time of great tectonic activity, as two plates of land drew closer to each other. A continent was created in the early Devonian by the collision of two tectonic plates. In the near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidized iron of drought conditions.
