Planolites is an ichnogenus found throughout the Ediacaran and the Phanerozoic that is made during the feeding process of worm-like animals. The traces are generally small, {{cvt|1|-|5|mm}}, unlined, and rarely branched, with fill that differs from the host rock.{{cite web |title=Planolites |url=http://ichnology.ku.edu/invertebrate_traces/tfimages/planolites.html |website=KU Ichnology |publisher=IBGS Research Group}}
