K/T boundary layer
MODEL RELEASED. K/T boundary layer being examined by a tourist. This geological boundary is a thin layer of clay containing iridium,separating older Cretaceous (K) and younger Tertiary (T) rocks (white and red sandstone). The boundary layer is only a few centimetres thick,but is found worldwide. It is thought to have been formed from material ejected by the impact of a large asteroid around 65 million years ago. This is thought to have triggered the extinction of the dinosaurs,along with many other forms of life. Photographed in the Bottaccione Gorge,near Gubbio,Italy
