Here is a rare trilobite from an unusual site. This is an Olenus sp. from the Upper Cambrian of Sweden. This trilobite is outstretched and exhibits fine detail. The individual thoracic segments are easily seen, and the tiny pygidium is intact. The trilobite is well presented on the natural plate of shale that is just covered with other trilobite parts, including another near-complete Olenus. This is a good example of the rare Olenus from Sweden.
