    "Trilobites are the most lifelike of fossils―many well-preserved specimens belie their great antiquity and seem almost ready to arch their bodies, peer about with their compound eyes, and crawl forward as if to complete a journey that was interrupted hundreds of millions of years ago."―from the ForewordCited by: Trilobites were abundant and diverse in the seas that covered Ohio during the Silurian Period but many of the specimens have been destroyed or altered by the process of limestone changing to dolomite. However, excellent examples of Silurian trilobites are occasionally found. Common species are Bumastus, Calymene, and Dalmanites.

    The Silurian Fukata Formation of the Yokokurayama Group, Kochi Prefecture, Shikoku has been biostratigraphically dated using conodonts, cephalopods and trilobites that collectively indicate the upper Wenlock or lower Ludlow (Kobayashi & Hamada, ; Kuwano, , ); however, see Männik et al. for uncertainties with the conodont by: 3. It is notable that some specimens only have a rectangular-shaped glabella P.S., Hou, J., and Fusco, G.
