Mold Coated Cast with Gold Coated Replica

Caption

This is a high fidelity rubber mold of hadrosaurid dinosaur teeth, with a gold coated replica for measurement of roughness of the tooth surfaces. The surfaces have scratches that were created as the dinosaur fed on vegetation 67 million years ago, and measuring the roughness can reveal what kind of food they ate. The original teeth are too large to transport to the instrument that measures roughness. The image below shows the roughness of a small area, with colors representing the heights of ridges, troughs and peaks on the surface.
