Aulacopleura koninicki Czech Republic Trilobite

A large and beautiful part/counterpart specimen of this classic Bohemian species, here wonderfully preserved and covered with a white oxide patina. A most collectable trilobite. Please reference Riccardo Levi-Setti's book, Trilobites for more examples of these remarkable Czech species. These magnificent trilobites are getting less available as the government restricts collecting and older sites become exhausted, or off-limits. The right eye is missing in the part plate, otherwise this one has wonderful preservation.
