Here is a nice specimen of Cheirurus (Crotalocephalina) gibbus from the Devonian of Morocco. This specimen was recently acquired from the Richard Busch Collection. Busch was the Preparator/Asst. Curator at the North Museum in Lancaster, PA from 1965-1992. This large trilobite is extremely 3-dimensional and very nicely preserved. The bug is outstretched and exhibits very good detail. The small eyes are quite distinct, and the short genal spines are easily seen. The triangular pleurons terminate into points, and the pygidial spines are clearly defined. The trilobite has cool, natural coloration and contrasts nicely with the lighter-colored matrix. The bug is well showcased on the block of dense limestone. This is a very nice-for-the-price example of this odd-looking trilobite from Morocco.
