Aulacopleura koninicki Silurian Proetid Trilobite

This is a particularly well preserved specimen of a member of the Order Proetida, Family Aulacopleuridae, known as Aulacopleura koninicki. Not that essentially all of the exoskeleton is preserved as a rich white patina that contrasts well with the dark matrix. Some examples of this trilobite have been found in Africa and Greenland, showing that it had a more global range than many others from the region of the Czech Republic.
