This Septarian nodule is a top-polished end slice, from Utah. One side is cut flat and covered with felt so that it will stand.

Septarian nodules consist of a clay-rich nodule that developed a rigid outer shell while the interior dehydrated and shrank, leaving polygonal cracks. The interior of the nodule later filled with calcite crystals. These nodules occur in various locations around the world and their exact method of formation is still debated.

Large cabinet specimen: About 4.7" x 4.3" x 2.4" (120mm x 110 mm x 60mm)
