Deep water fossil from Devonian Shale in Ohio. False colored from three different detector angles in a scanning electron microscope. Magnification is 600x.
SEM of a conodont tooth, acid etched from 500 million year old rock. Conodonts are extinct chordates resembling small eels maybe the size of the modern earthworm. Scientists are still unsure how these teeth were placed in most of the species. This specimen was .5 mm wide and was collected in Ohio.
Color-enhanced Scanning Electron Micrograph (SEM) of the surface of a plant showing glandular cells, called trichomes. These are capitate trichomes that have stalks. Magnification: 52X when printed 10 cm wide.
Color-enhanced two detector Scanning Electron Micrograph (SEM) of a plant leaf stem in cross section.
Magnification: 100X when printed at 10 centimeters wide.
