Here is a beautiful trilobite. This is a "true" Ceraurus pleurexanthemus from the Ordovician of Quebec. This inflated bug is wonderfully articulated and exhibits outstanding detail. Even the small free cheeks are present which is highly unusual. The granulose texture of the cephalon is quite evident and the sweeping genal spines are dramatically displayed. The pleurons terminate in sharp points and the long pygidial spines are easily seen. This large example of Ceraurus pleurexanthemus is almost as wide as it is long. The dark, thick-shelled exoskeleton of the bug contrasts nicely with the gray matrix. The fossil is well positioned on the semi-square plate. This is an outstanding example of Ceraurus pleurexanthemus from Canada.
