For Whom the Bell Tolls

Close-up of the hindquarters of a (appr.) 250 million years old Sahara trilobite sitting under an small bell glass container in my windowledge. Fossils of trilobites ('Butterflies of the Sea') were found as large as 78 cm. This specimen is not much larger than 7 cm. These hindquartes must me less than 4 cm.
