Radulichnus is an ichnogenus of trace fossil which resembles the marks produced by the action of a mollusc's radula on sediment. As an ichnogenus, its classification is based solely on appearance, and does not necessarily imply anything of the affinity of the organism which produced the trace.[1] However, fossils of Kimberella have been found at or near the ends of Radulichnus traces, leading to the possibility that some traces were made by Kimberella.
