This material is approximately 417 million years old. These rocks are locally called the Old Red Sandstone Formation (Stonehenge Coshestons).
The youngest sandstone sedimentary rocks at Stonehenge are the Oligocene and Miocene Period silicates. The Oligocene and Miocene Period sandstone sedimentary rocks comprise the fourth (4th) foreign construction material used by the Stonehenge builders.
