POLISH AND GLOBAL RECORD OF THE BIO-EVENT AT THE PRECAMBRIAN-CAMBRIAN BOUNDARY Summary The appearance of the morphologically complicated trace fossils in the lowermost part of the Lower Cambrian represents a bio-event marking a boundary between major stage in evolution of behaviour, which was controlled by a combination of environmental and biological factors.
