The topologic architecture of metazoan trace fossils may be subdivided into 3 clusters, 8 basic topologic configurations, 3 combined topologic configurations and 21 topoichnologic kinds, which are considered to be related to ethologic classifications of trace fossils in origin.

Analysis of their morphologies and features leads to the conclusi on that these structures might have been in connection with metazoan activity, bu t the possibility of their abiotic origin can not be ruled out.
