What are Devonian rocks?
The rocks formed during Devonian time are known as the Devonian System. These rocks occur on all continents both at the surface and as substrata. Extensive areas of North America, South America, Europe, and Asia are underlain by Devonian rocks. Subsequent folding has made such rocks common in many ancient fold belts.

What is a Devonian fossil?
The fossils of these remarkable animals come from the red rocks of Devon. Some lobefins are still around today, such as the famous “living fossil” fish, the coelacanth. A fossil creature from the Devonian discovered more recently has been hailed as a vital link between fish and the first vertebrates to walk on land.
How was the Devonian Fossil Gorge formed?
The Devonian Fossil Gorge is the star attraction. It was created by the Flood of 1993 and expanded by the Flood of 2008 when water topped the emergency spillway. The overflow washed away tons of soil, huge trees, and part of our road.

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.
