"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.

The remainder of the thorax was then easily split off. The pygidium came off with difficulty and in two pieces. All the pieces were then fastened together; and we thus obtained two specimens, one of which shows the underside of the Trilobite, and the Cited by: 7.

Despite occurring in deposits alongside other more typical-looking trilobites, they have a number of unusual features. Many specimens show “indistinct trilobation,” giving them a streamlined torpedo-like appearance.

Some of the drawings of fossils shown in these pages are the same drawings that the artists used to construct the Silurian reef diorama. Two trilobite specimens are in the collection from this locality, both are Ekwanoscutellum agmen of Lower Silurian (Telychian) age, but only the complete pygidium is figured here.
