Comments

One of the few items in my collection which was not self-collected. Given to me by another forum member. The location this was collected from is now paved over and has been closed for close to 2 decades. A rare find even at that site. 

 

Once known as Santeelampas oviformis, Kier (1980) assigned this to his early Biozone. Known from only a very small handful of sites in North and South Carolina's Castle Hayne, Warley Hill and Santee Limestone Formations.

 

One of the intriguing things about this echinoid is the lack of matrix inside of the test. You can see this in the first (featured) photo of the periproct. The light inside is what is seen through the paper-thin test.
