This lot contains 54 pieces having trilobites measuring from 4 to 9 mm. These trilobites are members of Order Agnostida (pronounced Ag-nós-t-eh-da), an order that appeared in the Lower Cambrian where they were diverse and plentiful The order declined to become rare in the Ordovician prior to their complete extinction by the end of the Ordovician period. Scientitists disagree whether agnostids were benthic or pelagic, and the systematic position of Order Agnostida remains undetermined. The agnostids were mostly blind and have a strong symmetry of head and rear size, making it hard to distinguish front from rear. The lot includes a label for each trilobite.
