Annelid Fossils

Because the annelids have soft bodies, fossilization is exceedingly rare. The best-preserved and oldest specimens come from Cambrian Lagerstätten such as the Burgess Shale of Canada, and the Middle Cambrian strata of the House Range in Utah. The Annelids are also well represented among the Pennsylvanian-age Mazon Creek fauna of Illinois.
