Woolly Mammoth Ivory, SEM
The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived during the Pleistocene epoch. This is a section of a tusk imaged in a scanning electron microscope (SEM) and then colour enhanced. This ivory is a good substitute for Africa Ivory and is often used for jewellery. This specimen was collected from melting permafrost in Alaska. The field of view of this image is 144 um. The SEM magnification was 7, 670x. The red objects are an unidentified protozoa that lived in the cracks and tunnels inside the tusk as it was submerged in water for thousands of years. These protozoa are an indication that this is not a sample of Elephant Ivory.
