Extract

The genus Cyclus contains a number of small Arthropoda which are found in the Carboniferous rocks of Europe and the United States. As a rule the fossils are small, less than an inch in diameter, and very often they are enclosed in ironstone nodules. Consequently they are generally overlooked and are rarely found in collections.
