Here is a attractive double of two large trilobites of the species Paradoxides gracilis from the Czech Republic. Both specimens have the librigena what is unusual for a Czech Paradoxides of this size. Unfortunately is the matrix a little bit to small so that both trilobites are not completely preserved but all in one is this piece anyway a nice and inexpensive showpiece of this classical czech trilobite.
 The plate is about 170 x 150 mm large.
