Hee is a relatively difficult-to-obtain trilobite from South America. This is Acastoides verneulli from the Devonian of Bolivia. This trilobite was part of the Edward Books Collection. At one time, Bolivian trilobites were obtainable. However, most of the local diggers got involved in the cocaine business which was much more profitable. These trilobites are found in concretions and usually in a contraflexed position. This trilobite is almost perfectly prone and nicely articulated. The bug is 3-dimensionally preserved and exhibits fine detail. The individual lenses of the compound eyes are easily seen. The individual thoracic segments are quite evident and the small, triangular pygidium is intact. This is a very nice example of this unusual Phacopid trilobite.
