Septarian Nodule Slab
Polished septarian nodule slabs from Kane County, Utah. Cut thin enough to let some light pass through, these formations will truly stand out.
This fossil mud comes from the Cretaceous Period, around 50-70 million years old. These specimens have been cut and polished in order to show the formations of yellow calcite and aragonite inside grey limestone.
