Abundant and varied trilobite trace fossils are recognized and described in the Cambrian sequence of the Holy Cross Mountains. Cruziana and Rusophycus are stratigraphically significant and some of the described traces may be used as local index fossils. The first recognition of the Cruziana barbata ichnozone in Poland is made and it occurs in the uppermost Middle Cambrian. A new position for the Middle/Upper Cambrian boundary is established. Three new ichnospecies are described: Cruziana magna, C. regularis and Rusophycus crebus.
