SEM of a Conodont Tooth

Buy Add to Lightbox Download
SEM of a conodont tooth.  Acid etched from 500 million year old rock. Scientists are still unsure how these teeth were placed in most of the species.  Conodonts are extinct chordates resembling small eels maybe the size of the modern earthworm.  Classified in the class Conodonta. For many years, they were known only from tooth-like microfossils now called conodont elements, found in isolation. Knowledge about soft tissues remains relatively sparse. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity.  This specimen was .5 mm wide and was collected in Ohio.
