These samples were obtained at a specialty store and gift shop in Destin, FL in early 2014. The teeth had their bony roots still attached.
Figure 10: InLens detector. A frontal cross section of the interior of the tooth near the tip. This tissue is very spongy and filled with open spaces. The dark areas are the voids in the material. Inside the spongy structure are small particles. It is unclear whether this is dentin or some remnant of the pulp.
The ImageJ data found 33 particles. The average area was 0.171 μm2 with a standard deviation of 0.108. The average Feret diameter of a hole was 0.599 μm with a standard deviation of 0.195.
Figure 13: The EDS results for the shark tooth. Calcium, phosphorus, carbon, and oxygen are all present as expected. There are possibly peaks for sodium and fluorine.
