Gift to Margo
Here is an excellent example of C. besairiei that has been cut in cross section to expose the very fine detail internal septa. Some of the internal chambers are hollow and lined with calcite showing the complex geometry of the septa wall. The ammonite is 6 inches across.
These Lower Cretaceous ammonites are quarried commercially in Madagascar. They are found in a hard basal glauconitic sandstone layer known as the Cleoniceras Zone.
