"Triarthrus" is an upper-Ordovician trilobite found in New York State, eastern and northern Canada and Scandinavia. It is the last of the Olenid trilobites, which flourished in the Cambrian period. "Triarthrus" have been found in the Rome, New York area with soft body parts preserved in iron pyrite. This preservation has given scientists a rare opportunity to examine the gills, walking legs, antennae and digestive systems of trilobites, which are rarely preserved. "Triarthrus" is therefore commonly used in science texts to illustrate trilobite physiology.
