The base is defined as the first appearance of the trilobite ''Ptychagnostus atavus'' around million years ago. The top is defined as the first appearance of another trilobite ''Lejopyge laevigata'' around million years ago. The GSSP is defined in the Drumian section () in the Drum Mountains, Millard County, Utah, USA. The stage was also named after the Drum Mountains.
