SHARK TEETH
These shark teeth pages are dedicated to my very good friend Jim Craig who has recently passed away after a long illness. He prepared all of the superb digital images of the teeth that are illustrated with the exception of the images on the Cretalamna appendiculata page. All were taken by his Nikon Coolpix digital camera at high resolution. The very small teeth were taken through a microscope at various focal points and then layered together to achieve depth of field.
