Skolithos: One well-known occurrence of Cambrian trace fossils from this period is the famous 'Pipe Rock' of northwest Scotland. The 'pipes' that give the rock its name are closely packed straight tubes- which were presumably made by some kind of worm-like organism. The name given to this type of tube or burrow is Skolithos, which may be 30 cm (12") in length and between 2 to 4 cm (0.8 to 1.6") in diameter. Such traces are known worldwide from sands and sandstones deposited in shallow water environments, from the Cambrian period (542 to 488 m.y.a) onwards. source: http://en.wikipedia.org/wiki/Trace_fossil See the following links: http://www.envs.emory.edu/faculty/MARTIN/ichnology/Skolithos.htm http://www.ohiolink.edu/etd/send-pdf.cgi?toledo1116014816
